AIDS INTERCONNECTION (DMU, DAR) - DESCRIPTION AND OPERATION

** ON A/C NOT FOR ALL
1. General
A. Purpose of the Aircraft Integrated Data System
With the integration of modern, state-of-the-art technology like the fly-by-wire or the Full Authorized Digital Engine Control (FADEC) the complexity of the aircraft systems leads to the development of the Central Fault Maintenance System (CFDS) and the Aircraft Integrated Data System (AIDS).
While the CFDS is intend to assist the line maintenance in isolating faults, detected by the BITE functions of the individual aircraft system, the main objectives for the AIDS are more of a preventative nature.
Long term trend monitoring of the engines and the APU avoid expensive unscheduled maintenance actions outside the main base of the aircraft operator. Continuous monitoring of the engines and the APU is also intended to substitute fixed interval inspections by on demand maintenance.
In addition the AIDS is used for various tasks like hard landing detection, crew proficiency monitoring and any type of special investigations and trouble shooting on system level.

The main function of the AIDS is to convert various critical flight parameters into a recordable form.
The recorded parameters are then stored on one of the subsequent storage mediums:
  • A Digital Flight Data Recorder (DFDR / FDIMU configuration (FDIU part))
  • A Quick Access Recorder (QAR / FDIMU configuration (FDIU part))
  • An optional Digital AIDS Recorder (DAR / FDIMU configuration (DMU part)).
The stored data is also used to monitor the condition of the connected A/C systems.
Further functions of the system are:
  • Initiation of print reports
  • Easy access to the aircraft parameters through the MCDU
  • The possibility of free programmable recording of aircraft parameters on the DAR.
B. Realization of the Aircraft Integrated Data System
The AIDS is organized around the DMU which interfaces with other aircraft systems (see AIDS - System Block Diagram). Approximately 13000 parameters from the 50 ARINC 429 data lines are fed into the DMU.
Based on these parameters, the DMU performs several tasks, the result of which are either found on the SAR, on PDL floppy disks, on the MCDU screen or if they are downloaded through ACARS directly at the GSE computer in the airline ground station.
The Smart Access Recorder (SAR) shall be retrieve via the PDL.
(1) AIDS Part function:
The AIDS-part of the FDIMS monitors the data supplied by various aircraft systems. This data enables the operator to customize his maintenance-planning. Long-term trend-monitoring of the engines and the APU prevent expensive unscheduled maintenance actions outside of the main base from the aircraft operator. In addition the AIDS is used for various tasks like hard landing-detection, team-proficiency- monitoring and trouble-shooting on system-level.

(2) DFDRS Part function:
(Ref. AMM D/O 31-33-00-00).

3. System Description
A. General
F System Block Diagram ** ON A/C NOT FOR ALL
The AIDS mainly consists of the Data Management Unit (DMU) and an optional Digital AIDS Recorder (DAR). The DMU is the central part of the AIDS and is reconfigurable via the Ground Support Equipment (GSE).
The DMU is a high-performance avionic computer specialized for the acquisition of ARINC 429 DITS data and associated processing. The multi tasking architecture allows processing of the various tasks in real time.
An integral part of the DMU is the optional Smart Access Recorder (SAR). This function is based on a nonvolatile Solid State Mass Memory (SSMM) module which is used to store flight data. Sophisticated data compression algorithms ensure efficient usage of the limited capacity of the SSMM.

A further integral part of the FDIMU is the PCMCIA interface. This interface is able to accept rotate and solid state ATA disks to store SAR data, DAR data or generated AIDS standard reports.

B. System Architecture
(1) Hardware
  • a Data Management Unit (DMU)
  • an Digital AIDS Recorder (DAR) (option)
  • an in the DMU integrated Smart Access Recorder (SAR)

(2) Software
  • Boot Software
  • DMU Operational Software
  • DMU Database Software

(3) Generic function of the DMU
One of the generic functions of the DMU is the generation of reports as a result of specific events defined by trigger conditions.

The following AIDS standard reports are defined:
Most of these reports allow a change in the trigger limits or in the length of the report. In addition user specific trigger conditions can be created for each report by the use of the GSE based reconfiguration software. In addition to the above listed standard reports additional complete new reports can be programmed by the airline user.

The DMU is able to record AIDS data either by the use of the DAR or the integrated SAR. The storage medium of the DAR is a magnetic tape cartridge or an optical disk while the SAR stores the data in an Solid State Mass Memory. To read out the SAR data, use a floppy disk via the PDL.

The DMU provides various communication interface for operator dialogue and ground communications. The usage of these communication channels is mostly programmable. For example, reports can be either printed out, transmitted to the ground via ACARS or retrieved by the use of a floppy disk via the MDDU. That means each airline user can setup the DMU to support most efficiently the airline specific data link structure.

  • FDIMU (DMU-part) database software.

(7) Generic Function of the FDIMU (DMU-part)
One of the generic functions of the FDIMU (DMU-part) is the generation of reports as a result of specific events defined by trigger conditions.
Most of these reports allow a change in the trigger limits or in the length of the report. In addition user-specific trigger-conditions can be created for each report by the use of the GSE based reconfiguration software.
The airline user can programme more new reports.

The FDIMU can record AIDS data either by the use of the DAR, the SAR or the integrated PCMCIA interface.
The storage medium of the DAR is a magnetic tape cartridge or an optical disk while the SAR stores the data in a solid state mass-memory. To store data through the PCMCIA interface, an PCMCIA card in MS DOS format is necessary.
To read out the SAR data, use a floppy disk for the PDL or an PCMCIA card for the PCMCIA interface.

The FDIMU (DMU-part) gives different communication interfaces for operator dialogue and ground communications. The usage of these communication channels is mostly programmable.
For example, you can:
  • Print out a report
  • Transmit a report to the ground through ACARS
  • Retrieve a report by the use of a floppy disk through the PDL. That means each airline user can set up the FDIMU to support satisfactorily the airline specific-data-link structure.

  • Manual request of reports and SAR/DAR recording
  • Display of list of stored reports and SAR files
  • Online display of selected aircraft parameters
  • Various control and reprogramming menus
  • Entry for access to the PCMCIA card information

(b) PRINTER
  • Manually initiated (by MCDU) print out of reports
  • Automatic print out of reports
  • Print out of MCDU screens
  • Print out of software load messages

(c) PDL
  • Manually initiated (by MCDU) retrieval of reports and SAR files
  • Automatic retrieval of reports and SAR files

  • Automatic recording of AIDS data

(f) SAR
You can retrieve through the PDL the data from the SAR data storage buffer.
A remote print button (3TV) is on the pedestal in the cockpit to start manually some specific reports. Also SAR recording is triggered through the print button. The report/SAR channel assignment of the remote print button is GSE programmable.

(g) PCMCIA
The integrated PCMCIA interface contains an optional DAR recording function. With this function you can store SAR generated files and AIDS standard reports. Also it is possible to emulate a data loader function. When you use these functions, you must put an PCMCIA card in the PCMCIA interface.

J. General Functions of the DMU
(1) Identification of Location
The design of the DMU allows its use in A/C with different input parameters and different tasks for data evaluation, if the appropriate programs are implemented. To make sure this capability, the unit is able to identify A/C type information on the FDIU ARINC 429 DITS data bus. Depending on the occurrence of specific conditions or events, the DMU has trigger predefined actions. As a result of specific trigger conditions AIDS reports may be generated or data may be recorded on the DAR (optional) or stored in the DMU internal Smart Access Recorder (SAR). Print reports can be either printed out on the cockpit printer or transmitted via ACARS (optional).
SAR data are also retrieved via the Portable Data Loader (PDL).
Functions which are specific to A/C type (CFMI or IAE engines) are indicated in the respective logic definition.
The A/C type coding, parameter 17.1.304.00, is shown below:
Engine Type ! Bit No.
! 16 15 14 13 12 11
-------------------------------!----------------------------
For CFM 56-5 ! 0 1 0 0 1 1
For IAE V2500 ! 0 1 0 1 0 0
No code programming ! 0 0 0 0 0 0

If the code for no programming is received, the DMU works according to the A/C type code from the last flight. If there is no coding from the last flight, the DMU works with the CFMI type code.
(2) The A/C type coding, parameter 17.1.304.00, is shown below:
A history buffer is provided for the history data required by the AIDS reports and the DAR and SAR. It is the responsibility of the sampling task, to control this buffer and manage the history buffering. The management of the history buffer is determined by the parameter sampling table. It is possible to program additional parameters for history buffering via Ground Support Equipment (GSE).
(3) DMU Internal Parameter
Internally the DMU processed parameter are referred to as "Internal Parameters". All internal parameters are identified by a parameter number consisting of the EQ/SYS/LABEL/SDI. For the DMU applications up to 400 internal parameters can be created. In addition the parameter can be assigned with an alpha call-up code for identification through GSE programming.
Internal parameters are provided for:
  • DMU internal counter and timer
  • Filtered Parameters
  • Flags for certain flight conditions
  • Report status words
  • SAR channel words
  • additional global computed variables defined by the user
(4) Parameter Label Call-Up
Each parameter (ARINC 429 data word) transmitted on one of the connected data buses is selectable, you use: EQ, source system, label, SDI and number of data bits for display on the MCDU. The number of data bits can be omitted. The displayed parameters are updated once per second. The menus are shown in 'ADIS PARAM LABEL CALL-UP'. Up to 2 parameters can be displayed on one page. 8 pages can be selected via slew up/slew down button, which leads to a maximum number of 16 parameters to be monitored simultaneously.
If there are additional parameters in the future, it is possible to call them up in the same way without having to change the software.
Example for Parameter Call-up: EQ/SYS/LAB/SDI = 1A/2/156/01
(5) Parameter Alpha Call-Up (ACU)
For all the parameters for which an alpha code is mentioned in the parameter list. The selection is performed by their alpha codes.
If parameters from two systems are available, both parameters are displayed on the MCDU upon a single alpha call-up code entry. The display values will refreshed once per second. All numeric type alpha call-up parameters will displayed on the MCDU in engineering units. The display format is a floating point representation of max. 6 characters including the decimal point and the '-' sign, if applicable. In case of positive numbers without decimal point all 6 characters shall be available for digits. Display of leading zero shall be suppressed. The applicable units shall be displayed below the alpha call-up code on the MCDU screen.
Alpha call-up parameters, which consist of a combination of several discrete bits or packed discretes will displayed in HEX.
Discrete alpha call-up parameters shall be displayed using English status indications of max. 6 characters together with the actual bit status. The unit indication on the MCDU screen shall be 'DISCRETE'.
(6) Additional Parameter Programming
If a new label (parameter) is used in the DMU (for other than a parameter label call-up) it must be programmed via the GSE.

(7) Test Input Parameters
The DMU DITS ports no. 49 and 50 are dedicated test inputs. This ports are wired to the rear- and DMU test connectors. The test connector allows access to all ARINC 429 buses in the aircraft. The DMU DITS 'Test Inputs' are referenced with the GSE programmable equipment code.
(8) Additional Bus
If an additional ARINC 429 Bus is connected to one of the DMU ports, the characteristics of the new Bus (transmission speed, equipment code, system number) is programmable via the GSE for the appropriate port number. The new parameter is used for the purpose of no limitation label call-up, trigger logics, data recording and reports.
(9) Engineering Unit Conversion (EUC)
The DMU provide an 'Engineering Unit Conversion Table' to convert a selected group of input parameters (same as supplied with alpha call-ups) into the applicable engineering units. The EUC table is associated to the alpha call-up table.
The GSE reconfiguration software allow to add or modify the conversion constants. Modifications are made by specifying a single scale constant, number of data bits and sign.
(10) Special Rules for Kg and Deg C
All parameters for which an alpha acronym is defined in the parameter list is available for alpha call-up. With a single call-up system 1 and 2 parameters are displayed in engineering units.
The DMU is observe bit 18 and bit 27 of DMC label 305. If bit 18 = 1, then the parameter values are shown in print out and alpha call-up in the following units:
fuel flow (eng 1 and 2): lbs/hours instead of Kg/hours

L. General AIDS Function
The AIDS functionality is divided into the following major functions:
  • AIDS Reports
  • Smart AIDS Recorder (SAR) Function
  • Digital AIDS Recorder (DAR) Function
  • Input/Output User Function
  • GSE Readout Function
  • GSE Reconfiguration.
M. AIDS Reports
The AIDS Reports are AIDS monitor functions which have fixed trigger mechanism, fixed data collection and fixed output formatting. These reports perform the basic aircraft monitoring functions which are required. These monitoring functions collect parameters for trend analysis of the engines, the aircraft and the APU.
Aircraft data are also collected and automatically output during times of aircraft operational anomalies (e.g. engine over-temperature).
If a report is triggered manual by the remote print button, then the report is immediately generated (independent of any other trigger logic).
The manual or automatically generated reports (stored in the SSMM) can be transferred to the printer, the MDDU, the ACARS and the DAR/SAR.
Certain parameters for customer requirements are reprogrammable through the MCDU or by GSE.
Following AI AIDS Reports are available:
The AIDS Reports are AIDS monitor functions which have fixed trigger mechanism, fixed data collection and fixed output formatting. These reports perform the basic aircraft monitoring functions which are required. These monitoring functions collect parameters for trend analysis of the engines, the aircraft and the APU.
Aircraft data are also collected and automatically output during times of aircraft operational anomalies (e.g. engine over-temperature).
If a report is triggered manually by the remote print button, then the report is immediately generated (independent of any other trigger logic).
The manual or automatically generated reports (stored in the SSMM) can be transferred to the printer, the MDDU, the ACARS and the DAR/SAR.
Certain parameters for customer requirements are reprogrammable through the MCDU or by GSE.
Following AI AIDS Reports are available:
(1) History Buffer
There is a 20 s history buffer (pre event buffer) for 400 parameters with an average sampling rate of 4 per second. This buffer is intended to supply data for incorporation into the AIDS reports.

(2) Temporary Buffer for Manual Reports
For reports generated manually through the MCDU for printing or ACARS download a report buffer for one report is provided.

(3) Report Storage
A non-volatile memory for storage of at least 10 reports per different AIDS report type is provided.

  • report name (18 alphanumeric string),
  • print report format programmable text (2 header lines),
  • overall report inhibit (enable/disable),
  • engine specific trigger inhibits,
  • maximum number of automatically generated reports per flight,
  • maximum number of SSMM stored reports,
  • 16 GSE programmable security levels for depart evaluation on the GSE
(5) Report Trigger Definition

(a) Manual Report Request
The DMU provides via the MCDU a report selection menu to enable manual selection of reports for immediate generation and output to one of the following destinations:
Output Device ! Output Rule
_______________!_________________________
- Printer ! 2.1: Print Immediately
- ACARS ! 3.1: Downlink Immediately
- PDL ! (no rule defined)

(b) Manual Report Trigger via Remote Print Button
A remote print button function is cause a generation of specified print reports as a function of flight phase. The respective report trigger logic and the information about incrementing or not incrementing the appropriate report counter is programmable via GSE.

(c) Programmable Report Trigger
Each trigger logic consist of:
  • A programmable trigger logic code
  • A programmable trigger logic tree
Trigger logic trees are consist of parameter conditions. The following availablecombine parameter conditions are possible:
'AND', 'NAND', 'OR', 'NOR', 'XOR' and 'NOT'

The number of parameter conditions per logic tree is variable, as long as 200 lines of 76 charcters.
Parameter conditions are accomodate Numerical Parameters, Discrete Parameters and Hex Parameters. In case of Numerical Parameters the result of the parameters condition are determined by a numerical composition, which results in either of the results 'TRUE' and 'FALSE'.

(6) Report Output
AIDS reports are retrieved by several different output devices (Printer, ACARS Down Link, MDDU).

(7) Output Rule
For each AIDS report it is possible to program the applicable output rule via GSE. It is also possible via GSE to define an individual output rule for each type of trigger condition of a report, which is identified by the 4 digit trigger code.

(a) Output Rule No. 1.1
The report is stored in the non-volatile report buffer until there is a request for retrieval (e.g. print out, dump on PDL disk, ACARS downlink). After retrieval independent of selected output device the report is marked for deletion.
(b) Output Rule No. 2.1
The report is stored in the non-volatile report buffer. As soon as the printer is ready to accept data, the report is printed out and marked for deletion.
(c) Output Rule No. 2.2
The report is stored in the non-volatile report buffer and printed out as the end of flight. After printout, the report is marked for deletion.
(d) Output Rules No. 3.X
The report is stored in the non-volatile report buffer. As soon as the ACARS MU accept the data report is marked for deletion.

(8) Report Format Definitions
(a) Value Presentation
The presentation of the values in the reports is according to the operational range as listed in the parameter list.
E.g. GW = 80000 Kg is printed as 80000.
Negative values begin with an 'N'. For positive values the 'N' is replaced by an '0' or a digit.
E.g EGT = -55.0 deg. C is printed out as N550,
EGT = +42.5 deg. C is printed out as 0425.

If there are more digits shown in the report layout than the number of digits shown in the parameter list then leading zeroes are included.
E.g. LCIT = 80 deg. C is printed as 0080,
LCIT = -70 deg. C is printed as N070.

A report parameter which is invalid or not updated is replaced with '_' or 'X' characters.

(9) Definition of Engine Hours (EHRS)
EHRS = time between "Main Landing Gear (LH and RH) Compressed/Decompressed".
The EHRS is set to zero when an engine serial number change is recognized.

(10) Definition of Engine Cycle (ECYC)
ECYC = each climb = 1 ECYC
ECYC is incremented by one each time PH 5 is reached.
The ECYC is set to zero when an engine serial number change is recognized.

A non-volatile memory for storage of at least 10 reports per different AIDS report type is provided.

(15) Overall Report Definition
The following definitions are basically applicable to each AI AIDS Report:
  • Report number (two digit)
  • Report name (18 alphanumeric string)
  • Print report format programable text (2 header lines)
  • Overall report inhibit (enable/disable)
  • Engine specific trigger inhibits
  • Maximum number of automatically generated reports per flight
  • Maximum number of SSMM stored reports
  • 16 GSE programmable security levels for depart evaluation on the GSE.
(16) Report Trigger Definition
For each AI Standard AIDS Report, general and specific trigger definition (Trigger Codes) are performed (e.g. exceedance, stability, peak) and are GSE reprogrammable. Within fixed trigger logics only certain constants and limits are reprogrammable (refer to report definition).

(a) Manual Report Request
The FDIMU gives, through the MCDU, a report selection menu to enable manual selection of reports for immediate generation and output to one of the following destinations:
Output Device ! Output Rule
_______________!_________________________
- Printer ! Print Immediately
- ACARS ! Downlink Immediately
- PDL ! (no rule defined)

(b) Manual Report Trigger via Remote Print Button
A remote print button function causes a generation of specified print reports as a function of flight phase. The respective report trigger logic and the information about incrementing or not incrementing the appropriate report counter is programmable via GSE.

(c) Programmable Report Trigger
Each trigger logic consists of:
  • A programmable trigger logic code
  • A programmable trigger logic tree
Trigger logic trees consist of parameter conditions. The following available combination of parameter conditions are possible:
'AND', 'NAND', 'OR', 'NOR', 'XOR' and 'NOT'

The number of parameter conditions per logic tree is variable, as long as the limitation of 256 parameter conditions is not exceeded.
Parameter conditions have numerical parameters, discrete parameters and hex parameters. In case of Numerical Parameters the result of the parameters condition are determined by a numerical composition, which results in either of the results 'TRUE' or 'FALSE'.

(17) Report Output
AIDS reports are retrieved by several different output devices (Printer, ACARS Down Link, MDDU).

(18) Output Rule
For each AIDS report it is possible to program the applicable output rule via GSE. It is also possible via GSE to define an individual output rule for each type of trigger condition of a report, which is identified by the 4 digit trigger code.

(a) Output Rule No. 1.1
The report is stored in the non-volatile report buffer until there is a request for retrieval (e.g. print out, dump on PDL disk, ACARS downlink). After retrieval independent of selected output device the report is marked for deletion.
(b) Output Rule No. 2.1
The report is stored in the non-volatile report buffer. As soon as the printer is ready to accept data, the report is printed out and marked for deletion.
(c) Output Rule No. 2.2
The report is stored in the non-volatile report buffer and printed out at the end of the flight. After printout, the report is marked for deletion.
(d) Output Rules No. 3.X
The report is stored in the non-volatile report buffer. As soon as the ACARS MU accepts the data report is marked for deletion.

(19) Report Format Definitions
(a) Value Presentation
The presentation of the values in the reports is according to the operational range as listed in the parameter list.
E.g. GW = 80000 Kg is printed as 80000.
Negative values begin with an 'N'. For positive values the 'N' is replaced by an '0' or a digit.
E.g EGT = -55.0 deg. C is printed out as N550,
EGT = +42.5 deg. C is printed out as 0425.

If there are more digits shown in the report layout than the number of digits shown in the parameter list then leading zeroes are included.
E.g. LCIT = 80 deg. C is printed as 0080,
LCIT = -70 deg. C is printed as N070.

A report parameter which is invalid or not updated is replaced with '_' or 'X' characters.

(20) Definition of Engine Hours (EHRS)
EHRS = time between "Main Landing Gear (LH and RH) Compressed/Decompressed".
The EHRS is set to zero when an engine serial number change is recognized.

(21) Definition of Engine Cycle (ECYC)
ECYC = each climb = 1 ECYC
ECYC is incremented by one each time PH 5 is reached.
The ECYC is set to zero when an engine serial number change is recognized.

(22) Definition of Engine Running Time (ERT)
ERT = parameter 7C.1.050.01 engine 1
parameter 7C.2.050.10 engine 2

N. Standard Header for Print Reports
A standard header to be printed on each report is installed.
The header data is taken at the time when the respective report is generated. The following symbols are used for the value fields:
'A' = any character in the range from A..Z,
'1' = digits possible (0, 1),
'9' = any digit in the range from 0..9,
'X' = any character or digit in the range from A..Z
and 0 .. 9,
'.' = checksum.

O. DMU Programming
Two different types of software packages are given. The DMU operational software and the DMU database software. These two software types have to be load into the DMU to give the complete functions. Only the DMU database software are subject of customer reprogramming. In addition a subset of the configuration data provided by the DMU database are reconfigurable on board the aircraft, via the MCDU.

(1) Operational Software Programming
Reprogramming of the operational software is only necessary, if a new modified software version is required or due to recognized software faults or future sytem modifications. Configuring the DMU for the specific requirements and applications of a customer shall require only reprogramming of the database by the use of the GSE reconfiguration function. Modification of the microprocessor code of the DMU operationalsoftware is reserved to the DMU vendor.

(2) Database Programming
The DMU database is reprogrammable by the use of the GSE reconfiguration software. An initial DMU database software is provided by the DMU vendor. This initial database is provide the configuration data required for the AI defined standard reports.
A lockout mechanism is provided for the GSE reconfiguration software, which prevents the AI reserved functions and constants from being modified by the customer.
A subset of the configuration data of the AI standard DMU database is reprogrammable by the customer via the GSE. Furthermore the customer have the possibility to define additional trigger conditions, reports and global variables. Also the parameters recorded on the DAR or SAR are determined by the GSE programming.

(3) On-Board Reprogramming
A subset of the reconfiguration data supplied by the DMU database is reprogrammable on-board the aircraft via the MCDU.
All the GSE programmable constants are on-board temporary reprogrammable. A distinction is made between those constants, which are only allowed to be modified with AI authorization, and those constants, which are allowed to be modified by the customer.

(4) Software Loading
To achieve the complete functionality of the DMU, the operational software and the DMU database software has to be loaded into the DMU.
the DMU operational software and database software is delivered on 6 seperate 3.5 inch (operational: 3, datbase: 3) 1.44 Mbyte floppy disks and are separately loadable. That means, loading of the database is not require necessarily reloading of the operational software. This is to speed up the process of software loading, if the operational software is not affected. Reloading of the operational software is always require also reloading of the database software.
If the operational software and the DMU database software are loaded sperately, a compatibility code is used to ensure, that the database software matches the currently loaded operational software version.
Loading of software into the DMU is performed automatically without any operator interactions via the MCDU.
That means immediately after insertion of a software load disk in the MDDU, the software load process is started.
Loading of either operational software or database software is only enabled, if the 'MDDU Available' discrete is set to 'Low'.

(a) System Software Application Check
Before the DMU starts overwriting the currently loaded operational software or database software, it is verified that the new update matches the DMU hardware configuration and A/C type identification.
Additional to the database software, the DMU verified, before overwriting the database software, whether the new database update addresses the concerned DMU if the update is dedicated to a specified aircraft by the optional aircraft selection information.
The following controls are performed by the previous System Software and by the Boot Software before to erase the flash prom and to upload the new System Software:

  • check that the discrete LOAD ENABLE or discrete PDL ENABLE is set.
    The set of one of those discretes implies that the A/C is on ground.
  • check that the identification of the Boot Software on the PROM is in accordance with the one contained in file ACQUIT.MEM.
  • check that the hardware configuration (Part Number, Number of CPU card and reference of CPU card) is in accordance with the one contained in the file ACQUIT.MEM.
  • check that the engine types is in accordance with the one contained in the file ACQUIT.MEM.
If the first control failed there is no answer to the ADL (or PDL).
If the first control is completed the DMU is read the file ACQUIT.MEM and perform the last 3 controls.

If they are completed the DMU is:
  • boot to the Boot Software
  • erase the flash PROM (System Software and Setup Database memory)
  • upload the new System Software
The first time a new System Software runs all memorized data is cleared in:
  • Report mass memory,
  • SAR mass memory (record and statistic),
  • Temporary change,
  • Engine serial number, computed hours and cycles,
  • APU offset hours and cycles,
  • Divergence and delta N1 summary,
  • Bite history.
ACARS and printer queues are cleared.

(b) Database SW Applicability Check
The following controls are performed by the System Software before to erase the flash prom and to upload the new Setup Database:
  • check that the discrete LOAD ENABLE or discrete PDL ENABLE is set.
    The set of one of those discretes implies that the A/C is on ground.
  • check that the identification of the System Software in the PROM is in accordance with the one contained in file ACQUIT.MEM.
  • check that the A/C identification (A/C tail) is in accordance with the list contained in the file ACQUIT.MEM.
If the first control failed there is no answer to the ADL (or PDL).

If the first control is completed the DMU is read the file ACQUIT.MEM and perform the last two controls. If they are completed the DMU is:
  • memorize all the list of A/C identification,
  • clear the Setup Database in flash PROM,
  • upload the Setup Database files,
  • verify the validity of the loading,
  • start system software process.
The first time the System Software runs with the a new Setup Database the following data are cleared:
  • Report mass memory,
  • SAR statistic memory,
  • Temporary change.
P. FDIMU (DMU-part) Programming
Two different types of software packages are given. The FDIMU (DMU-part) operational software and the FDIMU (DMU-part) database software. These two software types must be loaded into the FDIMU to give the complete functions of the FDIMU (DMU-part). Only the FDIMU (DMU-part) database software is a part of customer reprogramming.

The FDIMU (DMU-part) operational and database software are delivered on separate 3.5 inch 1.44 Mbyte floppy disks and are separately loadable. That means, loading of the database is not required necessarily reloading of the operational software. This is to speed up the process of software loading, if the operational software is not affected. Reloading of the operational software is always required also reloading of the database software.

  • Verifies the validity of the loading
  • Starts the system software process.
The first time the system software runs with the a new setup database the following data are cleared:
  • Report mass memory
  • SAR statistic memory
  • Temporary change.
(5) Programming via PCMCIA Interface
The PCMCIA media can be used as a Portable Data Loader (PDL). The emulation of PDL functions contains of loading operational and database software.

(a) Operational Software Loading
For the operational software loading, a system file 'SOFTWARE.CNF' must be presented on the root directory of the PCMCIA media. No loading is performed if the file 'SOFTWARE.CNF' is not present on the media. This file contains the name of one or several directories where software to be loaded can be found. Each of these directories contain the same files as on the PDL disks.
No loading is performed, when at power-up an inserted PCMCIA media is detected.

(b) Customer Database Loading
For the customer database loading, a system file 'DATABASE.CNF' must be presented on the root directory of the PCMCIA media. No loading is performed if the file 'DATABASE.CNF' is not present on the media. For successful operation use the same condition as for operational software loading.
Q. AIDS Data Recording
The DMU is able to record AIDS data on an external DAR (Digital AIDS Recorder) and/or a SAR (Smart AIDS Recorder) integrated in the DMU. The storage medium of the DAR is a magnetic tape cartridge or an optical disk, the SAR uses solid state mass memory (SSMM) for data storage.
Continuous as well as intermittent (only DAR) or event controlled data recording is possible. Therefore a set of start and stop triggers are individually user programmable for each recording channel.

Continuous as well as intermittent (only DAR) or event controlled data recording is possible. Therefore a set of start and stop triggers are individually user programmable for each recording channel.
It is also possible to emulate the SAR or DAR function via the PCMCIA interface. Therefore a PCMCIA media must be installed. In case of installed PCMCIA media the programmed DAR frame are automatically recorded on this media. If both media, PCMCIA and DAR, are installed, the same frame are sent to both media. Manual START/STOP function via the MCDU is available as one media is ready for recording. A disk space ratio reserved for DAR frame recording is programmable by the GSE.
It is possible to provide other disk space ratios for other kind of data like SAR/Report data. The disk space management is programmable on the GSE. The default adjustment is, whole space of the media for the DAR recording.
R. Smart AIDS Recorder
The SAR is a part of the DMU. External ARINC-429 or internal parameters from the FDIMU can be stored in compressed form. The memory is a 2.0 MByte Solid State Mass Memory (SSMM).

Three different modes are possible:

Data Recording
  • Storage of up to four user predefined datasets (each up to64 samples per second) between a start eben and a stop event.-
Extendend Troubleshooting
  • Storage of up to four user predefined datasets (each up to 64 samples per second) with pre event data when start event is met
  • 25 events are possible
  • The data is collected for each event for up to 10 minutes composed of up to
  • 5 minutes of history data plus up to 5 minutes of real time data.
Event Recording
  • Storage, when an event is detected, of a user predefined data set (15 selectable parameters) specific for each event
  • Up to 50 different events are possible.

Event Recording
  • Storage, when an event is detected, of a user predefined data set (15 selectable parameters) specific for each event
  • Up to 50 different events are possible.
(1) SAR History Buffer
For each recording channel a history buffer is provided to facilitate pre-event recording. With the appropriate selection of the sampling rate and number of parameters, the history buffer provides pre-event recording. It is possible to enable/disable individually and independently each event through GSE or via ACARS uplink.
(2) SAR Start/Stop Control
(a) Manual Start/Stop Control
It is possible to start or stop the SAR recording channel manually via the MCDU. A menu for manual request of SAR recording is provided.
In the case that an automatically triggered recording is active, it is possible to start the SAR recording manually. The recording is stopped until both, the manual stop command and all affected automatical stop trigger condition have become true. If an automatically trigger becomes true during manually triggered recording, the recording also continue, until both, the manual stop command and all affected automatical stop trigger conditions have become true. A manually initiated recording is only be stopped by:
  • manual stop command
  • DMU power interrupt > 200 m/sec.
  • Max. recording time limit of SAR channel is exceeded

(b) Automatical Start/Stop Trigger
The start and stop trigger condition for the SAR is programmable on the GSE and supplied to the DMU by the setup data base.
An automatically triggered recording is stopped by:
  • The associated stop trigger condition
  • DMU power interrupt > 200 m/sec.
  • Max. recording time limit of SAR channel is exceeded
(3) SAR Start/Stop Control
(a) Manual Start/Stop Control
It is possible to start or stop the recording of the SAR recording channel by manual request via the MCDU. A menu on the MCDU provides selective Run/Stop control for each SAR recording function. Manual start/stop control of the SAR is independent from the GSE programmed automatically trigger conditions.
It possible to start the SAR recording manually even if automatically triggered recording is active. In this case the recording does not stop until the manual stop command and all affected automatically stop trigger conditions become true.
NOTE: If there is an automatically triggered condition during a manually triggered recording the FDIMU saves this information until there is an associated stop trigger. This lets the FDIMU to continue recording after the manual stop command in the case, that the automatically start trigger condition is no longer true, but the associated stop trigger condition does not become true.
A manually initiated recording only stops:
  • Through a manual stop command
  • If the power interrupt of the FDIMU is greater than 60 seconds
  • When the max. recording time limit of the SAR channel is exceeded.
(b) Automatic Start/Stop Trigger
The start and stop trigger condition for the SAR is programmable on the GSE and is supplied to the FDIMU by the setup data base.
An automatically triggered recording stops:
  • Through the associated stop trigger condition
  • If the FDIMU power interrupt is greater than 60 seconds
  • When the max. recording time limit of the SAR channel is exceeded.
(4) Datatransfer between SAR and PDL
To copy SAR data from the DMU to a floppy disk use the PDL. The SAR is retrieved via PDL automatically. File selection and automatic dump disc generation is done via GSE.
The recording is aborted in case of following conditions:
  • Recording time exceeds GSE defined limit
  • Downloaded data exceeds disc memory space (1.4 Mbyte)
(5) SAR Data Retrieval via PDL
It is possible to copy recorded SAR data via the MDDU (if installed) or a PDL from the FDIMU to a floppy disc. The SAR is retrieved via PDL automatically.
S. GSE Functions
The Ground Support Equipment (GSE) for the DMU is based on an IBM-PC compatible computer with the operational software MS-DOS release 3.3, or later. The GSE computer is able to read 3.5 inch double-side high-density magnetic-disks providing a format of at least 1.44 MBytes.
The DMU vendor supplies appropriate DMU ground support software for the GSE, which provides the following functions:
  • Generating and editing the DMU database
  • Retrieval of compressed SAR data
  • Retrieval of stored AIDS Reports
  • Configuration Management Control and load history status.

(1) GSE Readout
The GSE readout function is a ground-based software application that provides the display and printout of AIDS collected information (AIDS reports and SAR files) using a DMU external IBM compatible personal computer. AIDS data dump disks are provided to extract AIDS reports and/or compressed SAR files for decompression and for display/printout.
(2) GSE Reconfiguration
The GSE reconfiguration function is a ground-based software application that provides for the reprogramming of certain aspects of the AIDS functions using a DMU external IBM compatible personal computer.
T. MDDU/PDL Functions
The DMU has an interface to the MDDU (if installed), which is compatible to the Airborne-Computer High-Speed Data-Loader according to ARINC Report 615. The MDDU can be provided either by an Airborne Data Loader (ADL) or a Portable Data Loader (PDL).
In case of the ADL options, the MDDU is permanently installed in the aircraft cockpit. If a PDL is used for the MDDU, only a connector is installed in the cockpit.
The PDL is connected to this connector only on demand. A discrete signal (PDL enable) indicates, that the MDDU/PDL is available for the DMU. Each time a plug from a PDL is connected to the DMU, the "PDL enable" - Pin is connected to ground. This indicates the DMU, that a communication for up- and download from and to the PDL is possible.
It is possible to connect a PDL directly to the test connector on the front of the DMU by the use of an adapter cable.
The MDDU/PDL provides the following tasks, if the MDDU SEL discrete (or PDL enable) is connected to ground:
  • Download of SAR data, which are stored in the SAR memory
  • Download of AIDS reports, which are stored in the FDIMU internal solid state memory
  • Upload of the DMU system software
  • Upload of the setup data base from and to the PDL.

(1) Report Content Reducing to Data Lines
All reports transmitted to ACARS are stripped off from information which is not necessary for ACARS. The data lines including line identifiers without checksum are transferred. Each transmitted value is separated by a comma. After each line a slash is transmitted as a line separator.
(2) Special Rules for the Transmission of Report to ACARS
For the transmission of reports to ACARS there are special rules as follows:
  • there is no character separating the line identifier and the first data value in each report data line,
  • only one comma character ',' separate each data value in a report data line,
  • only one comma character ',' separate each word in a report text line,
  • only one slash character '/' follow each line in the report.
(a) The first row gives the airline specific messages.
For example
'A02/A32002,1,6/CCA9C-AA,JAN03,045439,OMDB,OBBI,0501/'
represents:

1 The first line (three characters) represents the Imbedded Message Identifier (IMI).
This field allows the identification of the report.
For example 'A02' represents the report 02.

2 The second line (ten characters) gives the Aircraft Identification (Tail Number).
For example 'A32002,1,6' represents:
  • the first four characters identify the A/C type (A320 in this case)
  • characters 5 and 6 identify the report number (02 in this case)
  • 7th character is a comma ','
  • 8th character is the number of current Multiblock (1 in this case)
  • 9th character is a comma ','
  • 10th character is the number of total Multiblocks (6 in this case).

3 The next line (next characters) represents the first data value of the report.

For example
'CCA9C-AA,JAN03,045439,OMDB,OBBI,0501'
represents:
  • the first eight characters 'CCA9C-AA' represents the report line identifier (CC) and Aircraft Identification (A/C ID) ('A9C-AA' in this case)
  • 9th character is a comma ','
  • characters 10 thru 14 'JAN03' represents the date (DATE) (Month and Day)
  • 16th character is a comma ','
  • characters 16 thru 21 '045439' represents Universal Time Coordinated (UTC) (Hours, Minutes and Seconds)
  • 22nd character is a comma ','
  • characters 23 thru 26 'OMDB' represents Departure Airport (FROM)
  • 27th character is a comma ','
  • characters 28 thru 31 'OBBI' represents Arrival Airport (TO)
  • 32nd character is a comma ','
  • characters 33 thru 36 '0501' represents the Flight Number (FLT) (501 in this case).

(b) From the second line to the end of the message comes the report content.
The first two characters of each report line correspond to the report line identifier (for example C1, C2, CE, ... ).
Directly after each line identifier, you can find the value of the first parameter of the line, then all the parameters separated from each other by a comma ','.
Each line of the raw data can be decoded by crosschecking its content with AM31-37 report layout.

C. MCDU Functions and Rules

F MCDU ** ON A/C NOT FOR ALL
Some of the AIDS functions are controlled by the MCDU.
The MCDU display has 14 lines, each line has 24 characters. Line 1 is used as a title line or to show data to which the operator does not have access. Line 14 is used as a scratchpad line for entering data into the system.
Lines 2 through 13 are data lines arranged into six pairs (lines 2-3, 4-5, 6-7, 8-9, 10-11, 12-13). Each pair of lines has a label line and a data line. The data lines are adjacent to the Line Select Keys (LSK), and the label line is above the data line.
The line pairs are referenced by LSKs as shown below and in the menu figures:
LSK CRT Lines
1L and 1R 2 and 3
2L and 2R 4 and 5
3L and 3R 6 and 7
4L and 4R 8 and 9
5L and 5R 10 and 11
6L and 6R 12 and 13


The LSKs allow entry of data into a field and access to a data or a function identified by that field.

(1) MCDU Keys
The keyboard has the following alphanumeric keys:
Activating an alphanumeric key (0 through 9, A through Z, ., +, -, ° and / ) enters that character into the scratchpad of the MCDU.

If you push the MCDU MENU the display shows the MCDU menu. The other mode keys are not used for AIDS.
Function keys
'NEXT PAGE' = shows the next page
'ARROW up' = scrolls the displayed page up
'ARROW down' = scrolls the displayed page down
'CLR' = clears the scratchpad and data
fields.
' ° OVFY' = enters a ° into the scratchpad (not used
for AIDS).
There are three annunciators on the MCDU front panel:
'MCDU MENU' : This annunciator illuminates white when a system
linked to the MCDU requests the display.
'FAIL' : Not used for AIDS
'FMGC' : Not used for AIDS

(2) General Display Rules
No-valid and Missing Data
For all display fields, only valid data will be displayed. If a new update of a parameter was not received since the last sampling, then the parameter is marked as "Not Transmitted" ("XXX"). If a parameter is received with SSM indicating "not Normal Operation", then the parameter is marked with dashes ("---").
If the length of the parameter is too large (overflow) the display field shows Es. The possible length of parameters is between one and six characters (for example: "E", "EE", ...).
When a new page is accessed, or data are entered, it may require the computer to perform calculations before all the data to be displayed are available. In these cases, the screen is cleared. Then the portion of the display that is available and can be displayed is presented to the operator immediately. However, the data fields that are not available would be left as dashes and filled in as the data become available.

Small and Large Front Panels
The MCDU has two sizes of front panel. Generally all data on the data line are displayed on a large front panel. But data on the label line are displayed on a small front panel.
However, the following are exceptions:
  • Data with default values (or computer calculated values)
    which could be changed by the operator are displayed on a
    small front panel.
  • If two data entries are dependent upon each other, the
    independent data (those defaulted to or latest input by
    the operator) are displayed on a large front panel and
    the dependent data are on a small front panel.
  • For additional exceptions for AIDS which ensure more
    clarification in several menus.

(3) MCDU Special Symbols
There are special symbols on MCDU displays that indicate certain functions to the operator. Certain symbols show the operator what is available or if there is more information than is already displayed.
The following symbols are used in the displays:
< or > If this symbol appears next to an LS key, it indicates
that the activating line select key will only cause
the MCDU to display a different page (it is the
call-up of a page). Its name is displayed beside the symbol.
* If this symbol shows beside an LS key, it indicates that
the key causes the activation of a function (it is
the call-up of a function). The page displayed may also
change as a result. If the DMU or FDIMU needs some time to react,
during this time the star shall disappear to indicate
that the signal was registrated. As long as the star is
not shown, the related function can not be activated.
If an arrow shows beside an LSK, it shows
that the operator can press the key to set
data, without activating a function.
CO DO This indicates that the user can enter data here
(optional). Occasionally this data may be computed
and entered by the computer as a result of another
operator action.
This indicates that the data are necessary for the user
to input in order for the computer to perform the specific
function.
----- This indicates that the data will be displayed by the
computer when it has enough information to do so. The
user does not normally enter this information.
However, under certain circumstances he may be able
to alter the data.
Two vertical arrows (up or down) in columns 23 and 24
of the scratchpad show that vertical slewing is avaiable.
A horizontal arrow in column 24 of the title line show that
horizontal slewing is available from this page.
Activating the NEXT PAGE key will slew the page
horizontally.

(4) MCDU Color Coding
The color code is as follows:
----------------------------------------------------------------
! DATA ! MCDU COLOUR !
!-----------------------------------------!--------------------!
! Titles, comments, symbols of slewing ! White !
! dashes, minor messages, call-up of ! !
! page, scratchpad data entry ! !
!-----------------------------------------!--------------------!
! Operator modifiable data, selectable ! Cyan !
! data, brackets call-up of function ! !
!-----------------------------------------!--------------------!
! Operator nonmodifiable data-active ! Green !
! data ! !
!-----------------------------------------!--------------------!
! - Mandatory data (boxes) mandatory ! !
! operator action required ! Amber !
! - Important messages ! !
!-----------------------------------------!--------------------!
! Constraints max altitude ! Magenta !
!-----------------------------------------!--------------------!
! Temporary situation ! Yellow !
!--------------------------------------------------------------!

(5) MCDU Vertical Slewing
Certain pages in the computer contain more data than will fit on a single page (a page longer than the six pairs of lines available on the display).
In these cases, data are arranged on a 'drum'. In these instances vertical slewing can be used to scroll the display up or down. Each press of a vertical slew key scrolls the MCDU display by one line pair, or by one block. A line pair is a line adjacent to an LS key and its label line. Holding the vertical slew key down scrolls the MCDU display at a rate of 2 line pairs per second. The arrows will be displayed in columns 23 and 24 of the scratchpad when vertical slewing is available.

(6) General Display of a Page
  • Only the selectable functions or page call-ups are displayed.
  • On a page, some prompts are displayed following a logic dependent on external parameters. In such cases the promt is added or deleted.
  • Prompts that are used on several pages have to be displayed at the same place on the different pages.
    e.g.: RETURN at 6L
    PRINT at 6R

(7) Acknowledgement of User Action
Each time the MCDU user activates an LS key or a mode key, he receives an acknowledgement of his action.
The new page also displays an acknowledgement of the operator (insertion of a value in a line, message, etc ...).
Examples:
  • if the user wants to enter a value into a field, he will have the following messages:
    'OUT OF RANGE' if the value is not within the range as expected by the system.
    'FORMAT ERROR' if the value does not have the correct format.
  • the message 'NOT ALLOWED' is displayed if an incorrect LS key is activated.
In case of the call-up of a function, the acknowledgement is made by deletion of the star '*'. This is next to the function name when the call-up is taken into account by the system.
If the system is not available a message is displayed (e.g 'Printer Busy').

(8) MCDU Data Entry
Data are entered into the computer through the keyboard.
First the data are entered from left to right into the scratchpad by activating the alphanumeric keys on the keyboard (similar to that of a type-writer). Only 22 characters may be entered into the scratchpad. If more than 22 are entered, they will be ignored. The 23rd key press will not be accepted by the computer and the computer will give no response.
After entry of the data into the scratchpad, the date are moved from the scratchpad into the correct data field. By activating the adjacent LS key, the scratchpad is cleared.

The computer checks the data for format and acceptability (out of range, entry not allowed into the field, etc ...).
If the data are incorrect, the system will leave the previous data in the data field and then display the associated message indicating the error in the scratchpad. To enter the correct data, the operator must do either of the following:
  • Clear the message from the scratchpad by activating the CLR key. The data that was incorrect will appear in the scratchpad. The operator can then correct the data or clear it out.
  • Enter new data into the scratchpad. This automatically clears the message being displayed and replaces the previous (incorrect) scratchpad data with the new data.
If the entry was rejected because an incorrect LS key was activated, the entry will be accepted if the correct LS key is activated.
To clear the scratchpad of entered or incorrect data, the CLR key can be used. One press of the CLR key erases the last character entered in the scratchpad. A second press of the CLR key erases the second last character. At the third press of the CLR key, all data in the scratchpad are deleted. The same process applies if the CLR key is held pressed.
Immediately the last character is cleared, one second later, the second character is cleared, after 2 seconds the entire scratchpad will be cleared of any data.
Certain data entries into a field also cause the displayed page to be changed automatically. In these cases, any scratchpad data are deleted. Otherwise, scratchpad data is retained when the displayed page is changed. During a page change, scratchpad entries are ignored.

(9) Clearing Data Fields
Data fields on the MCDU can be cleared using the CLR key.
Activating the CLR key when the scratchpad is empty results in CLR being displayed. This appears in columns 6 to 8 of the scratchpad. Then, activating the LS key adjacent to the data field results in clearing that data and the scratchpad line is cleared.
If the data have a default or computer calculated value, the data revert to this value. If the default value is cleared, the clearing has no effect and there is no message displayed.
To remove a CLR prompt from the scratchpad, the CLR key can be activated again once. Or any alphanumeric key can be activated erasing the CLR in the scratchpad and entering the alphanumeric. The computer must distinguish between the CLR key and C-L-R being entered into the scratchpad via alphanumeric keys. C-L-R does not enable the clearing function.

(10) MCDU Data Field Display
Generally, a data is displayed on two lines:
  • the label line above the data line,
  • the data line next to the LSK.
On the data line there are five kinds of display:
  • Cyan data if the data is already in the computer and the operator can modify it.
  • Green data if the data is already in the computer but it cannot be modified by an operator entry.
  • Cyan brackets (- -) if no value is defined and the operator can enter the data.
  • Amber boxes ( ) if no value is defined. Then the data entry is mandatory for the correct functioning of the system. Or for the achievement of the function described on the page or on the label line.
  • White dashes ( --- ) if the field is filled by the computer but not yet available. Due to lack of information or a computation has not yet been or a computation has no yet been achieved.
The entry format of data is described by the number of boxes or the place occupied by the brackets, or the spaces between brackets. On one data line, several data may be displayed and entered : the different fields are separated by a slash ('/').
Each field may be entered separately; it is identified by the number of slashes in front of the entered data:
e.g.: EQ/SYS/LAB/SDI
to modify the label, the operator has to enter into the scratchpad : '//label'.

(11) Clearing Messages
Any message that is displayed can be cleared by activating the CLR key. Messages are automatically cleared under the following conditions:
  • When data are entered into the scratchpad
  • When LS or MODE key is activated
  • When the reason is no longer valid.

(12) Use of more than one MCDU at the same Time
The DMU or FDIMU (if installed) communicates with one MCDU only at the same time. If MCDU communication is requested from any of these MCDU's while communication is already active on another MCDU, the DMU or FDIMU (if installed) responds with the message: "AIDS (TIMEOUT)".
F Several MCDU's ** ON A/C NOT FOR ALL
D. MCDU Operation
The MCDU is operated via several keys (line select, mode, function).
The acknowledgement of the user action is indicated on the screen.

(1) Entering the AIDS mode
F AIDS Main Menu ** ON A/C NOT FOR ALL
To initiate communication with AIDS via the MCDU, the operator activates the 'MCDU MENU' key. The MCDU will respond with the display of the 'MCDU MENU' page. This page indicates the selectable systems.
If the operator activates the Line key adjacent to 'AIDS', the communication is broken with the currently active system and the AIDS initial menu appears.

(2) MCDU Return Function
F MCDU - Return Function ** ON A/C NOT FOR ALL
The DMU will issue a MCDU 'RETURN' when the '<' and the sign 'RETURN' are shown in line 13 and the key 6L is activated. This means that the display will change to the previous 'higher' menu level.
The menus themselves are described in the following paragraphs.

(3) MCDU Display Print
F MCDU - Display Print ** ON A/C NOT FOR ALL
The DMU issues an MCDU display print when the sign 'PRINT' and the star are shown in line 13. It also needs 6R to be activated. The display content is printed in the same format as it is shown on the display when 6R on the MCDU is activated. If the necessity of the scroll function is indicated, which means that more information is available than shown on the display, the complete information is printed. Each of these print outs is transmitted with a header containing A/C identification, date, UTC, City pair and Flight number.
In the example, a display print initiation of the 'AIDS MAN REQ REP'-menu is shown.

(1) Parameter Call Up Menu
The parameter call-up functions are a part of the DMU operational software. The operation of the alpha call-up function will depend on the availability of an alpha call-up table and associated EUC table.
(a) Parameter Label Call-up
F Parameter Label Call-Up ** ON A/C NOT FOR ALL
Each parameter transmitted on one of the up to 64 ARINC 429 connected data buses are selectable for display on the MCDU screen. The selection are made using EQ, source system, label and SDI. Additionally the number of data bits to be used for decimal representation are selectable. The parts of the parameter number are isolated with a slash '/'.
The number of the data bits can be omitted. The default value is 18. The displayed parameters are updated once per second. Up to 2 parameters are displayed on one page. 8 pages can be selected via slew up/slew down button, which leads to a maximum number of 16 parameters to be monitored simultaneously.
Example : Parameter Call-Up with EQ and System Number
EQ/SYS/LAB/SDI = 1A/2/156/01

1 The procedure to select the Parameter Label Call-Up Menu is as follows:
  • Set 'AIDS' on the MCDU Menu.
  • Set 'PARAM' on the AIDS Main Menu.
  • Set 'PARAM LABEL CALL-UP' on the AIDS Param Call-Up Menu.
  • Enter the parameter (e.g. 1C/1/344/01/12) on the scratchpad
  • Set the 1L key

2 Menu Definitions:
_____________________________________________________________________________
! EQ ! ARINC 429 equipment identification: !
! ! two-digit hexadecimal character e.g. 1B (for SFCC) !
!-----------!---------------------------------------------------------------!
! SYS ! System Number: !
! ! one character (only 1 to 4) !
!-----------!---------------------------------------------------------------!
! LAB ! ARINC 429 Label: !
! ! three-digit octal character (valid entries 000 - 377) !
!-----------!---------------------------------------------------------------!
! SDI ! Source Destination Identifier: !
! ! valid entries 00, 01, 10, 11 and XX (XX represents a case in !
! ! which the DMU samples the parameter without looking at the !
! ! SDI field) !
!-----------!---------------------------------------------------------------!
! DATABITS ! Identifies which ARINC 429 bits to extract from the label !
! ! call-up parameter and show as decimal value (valid entries !
! ! 1 to 20) !
!-----------!---------------------------------------------------------------!
! VALIDITY ! Validity of the requested parameter: !
! ! '>' parameter has not been transmitted/updated. !
! ! 'Blank' parameter has been updated. !
!-----------!---------------------------------------------------------------!
! SSM ! Sign Status Matrix: !
! ! is taken from bits 31 to 29 of the parameter and shows in !
! ! binary form. !
!-----------!---------------------------------------------------------------!
! DECIMAL ! Decimal value of the parameter calculated using the 'DATABITS'!
! VALUE ! entry to specify the number of bits to use as data. The !
! ! decimal value is calculated assuming the extracted data bits !
! ! as a whole represent a 2's complement value. For example !
! ! 'DATABITS' of 12 results in the decimal display of ARINC 429 !
! ! bits 28 to 17 . A 'DATABITS' entry of 20 results in a decimal !
! ! display of ARINC 429 bits 28 to 09. If bit 29=0, then the !
! ! decimal equivalent of the two complement of the 'DATABIT' !
! ! value will be preceded with a negative sign. !
!-----------!---------------------------------------------------------------!
! BINARY ! Binary Data (bits 28 to 11) of the parameter are shown on the !
! DATA ! on the line below the label 'DATABITS 28-11'. !

(2) Parameter Call Up Menu
The parameter call-up functions are a part of the FDIMU (DMU-part) operational software. The operation of the alpha call-up function depends on the availability of an alpha call-up table and an associated EUC table.
(a) Parameter Label Call-up
F Parameter Label Call-Up ** ON A/C NOT FOR ALL
Each parameter transmitted on one of the up to 64 ARINC 429 connected data buses are selectable for display on the MCDU screen. The selection are made using EQ, source system, label and SDI. Additionally the number of data bits to be used for decimal representation are selectable. The parts of the parameter number are isolated with a slash '/'.
The number of the data bits can be omitted. The default value is 18. The displayed parameters are updated once per second. Up to 2 parameters are displayed on one page. 8 pages can be selected via slew up/slew down button, which leads to a maximum number of 16 parameters to be monitored simultaneously.
Example : Parameter Call-Up with EQ and System Number
EQ/SYS/LAB/SDI = 1A/2/156/01

1 The procedure to select the Parameter Label Call-Up Menu is as follows:
  • Set 'AIDS' on the MCDU Menu.
  • Set 'PARAM' on the AIDS Main Menu.
  • Set 'PARAM LABEL CALL-UP' on the AIDS Param Call-Up Menu.
  • Enter the parameter (e.g. 1C/1/344/01/12) on the scratchpad
  • Set the 1L key

2 Menu Definitions:
_____________________________________________________________________________
! EQ ! ARINC 429 equipment identification: !
! ! two-digit hexadecimal character e.g. 1B (for SFCC) !
!-----------!---------------------------------------------------------------!
! SYS ! System Number: !
! ! one character (only 1 to 4) !
!-----------!---------------------------------------------------------------!
! LAB ! ARINC 429 Label: !
! ! three-digit octal character (valid entries 000 - 377) !
!-----------!---------------------------------------------------------------!
! SDI ! Source Destination Identifier: !
! ! valid entries 00, 01, 10, 11 and XX (XX represents a case in !
! ! which the DMU samples the parameter without looking at the !
! ! SDI field) !
!-----------!---------------------------------------------------------------!
! DATABITS ! Identifies which ARINC 429 bits to extract from the label !
! ! call-up parameter and show as decimal value (valid entries !
! ! 1 to 20) !
!-----------!---------------------------------------------------------------!
! VALIDITY ! Validity of the requested parameter: !
! ! '>' parameter has not been transmitted/updated. !
! ! 'Blank' parameter has been updated. !
!-----------!---------------------------------------------------------------!
! SSM ! Sign Status Matrix: !
! ! is taken from bits 31 to 29 of the parameter and shows in !
! ! binary form. !
!-----------!---------------------------------------------------------------!
! DECIMAL ! Decimal value of the parameter calculated using the 'DATABITS'!
! VALUE ! entry to specify the number of bits to use as data. The !
! ! decimal value is calculated assuming the extracted data bits !
! ! as a whole represent a 2's complement value. For example !
! ! 'DATABITS' of 12 results in the decimal display of ARINC 429 !
! ! bits 28 to 17 . A 'DATABITS' entry of 20 results in a decimal !
! ! display of ARINC 429 bits 28 to 09. If bit 29=0, then the !
! ! decimal equivalent of the two complement of the 'DATABIT' !
! ! value will be preceded with a negative sign. !
!-----------!---------------------------------------------------------------!
! BINARY ! Binary Data (bits 28 to 11) of the parameter are shown on the !
! DATA ! on the line below the label 'DATABITS 28-11'. !

(b) Parameter Alpha Call-up
F Parameter Alpha Call-Up ** ON A/C NOT FOR ALL
For all the parameters, which are listed in the alpha call-up table. The selection is possible by their alpha codes. If parameters from two systems are available, both parameters are displayed on the MCDU upon a single alpha call-up code entry. The displayed parameter values are refreshed once per second.
All numeric type alpha call-up parameters are displayed on the MCDU in engineering units. The display format is a floating point representation of max. 6 characters including the decimal point and the '-' sign if applicable. In case of positive numbers without decimal point all 6 characters are available for digits. Display of loading zeros are suppressed. The applicable units are shown below the alpha call-up code on the MCDU screen.

8. Test BITE
F DMU Power-up Test ** ON A/C NOT FOR ALL
The DMU contains an Built-in Test Equipment (BITE) according to ARINC 604. The BITE is able to detect failures occuring in the DMU. The board, the functional block or the integrated circuit in which the failure appears is described by the failure message.
F DMU Power-up Test ** ON A/C NOT FOR ALL
The FDIMU contains Built-In Test Equipments (BITE) in according to ARINC 604 regulations. One is for the DFDRS part and a second is for the AIDS part. The BITE's are able to detect at least 95% of the possible failures in the FDIMU. The detected failures are divided in system internal faults (FDIMU, DAR) and external faults (connected systems). If a failure is detected the BITE stores the failure messages in the FDIMU BITE memory and sends these continuously to the CFDS through the ARINC 429 output bus. The failures can be called up through the CFDS on the MCDU display.
A. General Rules for the BITE
All facilities of the already existing hardware and software that can reasonably be used to detect faults of systems or system componnets are made available for the fault isolation and detection function.
In order to recognize transmission faults the ARINC 429 inputs of the DMU are monitored continuously for update, sign status matrix and if necassary parity.
The BITE of the DMU is able to distinguish between system internal faults (DAR and DMU) and external faults (connected systems).
The equipment supplier is propose a fault isolation and detection concept that finally accepted by the purchaser.

(1) For CFM-egines, (2) for IAE-engines

C. Power-On Reset of the DMU
After each Power-On-Reset (POR) due to a power interrupt greater than 200 msec the DMU perform a POR Built-In-Test (BITE).
The POR BITE is done after each POR independent of 'On Ground' or 'In Flight' condition.
The POR BITE is performed before the DMU application software is started and is complete after 2 seconds.

(1) Function of the POR
Following functions of the POR are automatically executed:
  • Power Supply / Battery Test
  • Microprocessor Function / Test of Microprocessor Control Circuitry
    (e.g. Timer, Watchdog, Interrupt Control)
  • System Bus / Interprocessor Communication Test
  • External Interface Test
    ( Wrap-Around Tests)
  • E(E)PROM Memory Test
  • Local SRAM Memory Test

(2) Procedure of Power-On Reset
It is possible to initiate the POR BITE via the MCDU as follows:
  • Push the Line Select Key (LSK) adjacent to '<CFDS' on the MCDU Main Menu
  • Push the LSK adjacent to 'SYSTEM REPORT/TEST' on the CFDS Main Menu
  • Push the LSK adjacent to '<INST' on the System Report/Test Menu
  • Push the LSK adjacent to '<DMU' on the Recorder Menu
  • Push the LSK adjacent to 'TEST>' on the AIDS menu
  • Push the LSK adjacent to '<DMU POWER-UP TEST'.
  • The CFDS Test Result Menu shows ''TEST IN PROGRESS xxS'
    (xx represents the approx. waiting time in seconds)

(3) Results of Power-On Reset
  • Positive:
    If the test is positive the message 'TEST OK' appears.

  • Negative:
    If faults are detected, the CFDS Test Result Menu appears. This menu shows the results of the manually initiated test DMU POWER-UP TEST, LRUs, FIN Number, the related ATA reference and the failure class (1,2 or 3). The ATA reference and failure class is displayed always on a MCDU line adjacent to a line keys.
    Two fault messages are displayed on a single MCDU page. If more faults exist mutiple pages must be used for the CFDS Test Result Menu.
D. Power-On Reset of the FDIMU
After each Power-On-Reset (POR) due to a power interrupt greater than 200 msec the FDIMU does a POR Built-In-Test (BITE).
The POR BITE is done after each POR independent of 'On Ground' or 'In Flight' condition.
The POR BITE is done before the FDIMU (DMU-part) starts the application software and is completed after two seconds.

(1) Function of the POR
The POR BITE does these tests:
  • Power Supply / Battery Test
  • Microprocessor Function / Test of Microprocessor Control Circuitry
    (e.g. Timer, Watchdog, Interrupt Control)
  • System Bus / Interprocessor Communication Test
  • External Interface Test
    (Wrap-Around Tests)
  • E(E)PROM Memory Test
  • Local SRAM Memory Test

(2) Procedure of Power-On Reset
It is possible to initiate the POR BITE via the MCDU as follows:
  • Push the line select key adjacent to '<CFDS' on the MCDU Main Menu
  • Push the line select key adjacent to '<SYSTEM REPORT/TEST' on the CFDS Main Menu
  • Push the line select key adjacent to '<INST' on the System Report/Test Menu
  • Push the line select key adjacent to '<DMU' on the Recorder Menu
  • Push the line select key adjacent to 'TEST>' on the AIDS menu
  • Push the line select key adjacent to '<DMU POWER-UP TEST'
  • The CFDS Test Result Menu shows ''TEST IN PROGRESS xxS'.
    (xx represents the approx. waiting time in second)

(3) Results of Power-On Reset
  • Positive:
    If the test is positive the message 'TEST OK' appears

  • Negative:
    If faults are detected, the CFDS Test Result Menu appears. This menu provides the results of the manually initiated test DMU POWER-UP TEST, LRUs, FIN Number, the associated ATA reference and the failure class (1,2 or 3). The ATA reference and failure class must be displayed always on a MCDU line adjacent to a line keys.
    At maximum only two fault messages are displayed on a single MCDU page. If more faults exist multiple pages must be used for the CFDS Test Result Menu.
E. CFDS Menu Function
You can set the MCDU to show the failures that occurred during the last flight. The data comes from the CFDS (Ref. AMM D/O 31-32-00-00). You can also start system tests from the MCDU. To show the AIDS control data on the MCDU or to start a system test:
  • Push the line select key adjacent to 'CFDS' on MCDU Menu,
  • Push the line select key adjacent to 'SYSTEM REPORT/TEST' CFDS Main Menu,
  • Push the line select key adjacent to 'INST' on System Report/Test Menu,
  • Push the line select key adjacent to '<DMU' on the Recorder Menu
From the AIDS Menu, you can set:
  • <LAST LEG REPORT,
  • <PREVIOUS LEGS REPORTS,
  • <LRU IDENT,
  • <GND SCANNING
  • <TROUBLE SHOOT DATA
  • <CLASS 3 FAULTS,
  • <TEST,
  • <GROUND REPORT,
  • <SOFTWARE LOAD STATUS.
(1) <LAST LEG REPORT
F Last Leg Report ** ON A/C NOT FOR ALL
If you push the '<LAST LEG REPORT' LSK, the screen shows each class 1 and 2 failure detected during the last flight leg with:
  • The time when the failure occurred
  • The ATA number of the component
  • The FIN of the component
  • The class of the failure.
The screen shows a maximum of two failures at a time. If there are more failures, push the next page key on the MCDU keyboard. If there are no failures, the display shows the 'NO FAULT DETECTED' message.
If you push the LSK adjacent to the failure class the screen shows the trouble shooting data for that failure.
(2) <PREVIOUS LEGS REPORT
F Previous Legs Reports ** ON A/C NOT FOR ALL
If you push the '<PREVIOUS LEGS REPORT' LSK, the display shows each failure that has not been corrected from previous reports with:
  • The aircraft tailnumber
  • The flight leg
  • The date of the applicable flight leg
  • The time the failure occured
  • The ATA reference of the failure,
  • The class of the failure,
  • The FIN of the component.
