5. Primary Engine Parameters Description

A. N1 INDICATION
The N1 indication is displayed in analog and digital form. A needle below which the N1 digital value appears gives the analog indication.
The N1 actual analog display (needle) and the digital display are in green color in normal operation. 100 % correspond to 5000 RPM.
The color of the analog display changes from green to amber if N1 actual exceeds the N1 LIM value and from amber to red if N1 actual exceeds the N1 red line. However the digital display stays green and only turns red together with the analog display. In addition to draw better attention from pilots the needle pulses when N1 is in amber or red range.

The N1 indication is displayed in analog and digital form. A needle below which the N1 digital value appears gives the analog indication.
The N1 actual analog display (needle) and the digital display are in green color in normal operation. 100 % correspond to 5000 RPM.
The color of the analog and digital displays changes from green to amber if N1 actual exceeds the N1 MAX + 1% during more than 5 seconds. It changes from amber to red if N1 actual exceeds the N1 red line +0.1%.

The N1 indication is displayed in analog and digital form:

The N1 indication is displayed in percent in analog form from 20 % to 110 % rpm.
The N1 indication is displayed in digital form with 4 digits with a step of 0.1 % rpm from 0 % to 120.0 %.
A needle below which the N1 digital value appears gives the analog indication.
The N1 actual analog display (needle) and the digital display are in green color in normal operation. 100 % correspond to 5000 RPM.
The color of the analog and digital displays changes from green to amber if N1 actual exceeds the N1 MAX + 1% during more than 5 seconds. It changes from amber to red if N1 actual exceeds the N1 red line +0.1%.

B. N1 RED LINE
The N1 red line is represented by an arc shaped red ribbon situated at the end of the scale.
If the N1 actual value exceeds the N1 red line (even for a short period of time), a small red line appears across the N1 scale and then stays at the maximum value which has been reached. This indicates a N1 exceedance condition.
Should this condition occur, the small red line disappears only after a new take-off or after a maintenance action through the MCDU. The maximum value which has been reached is stored in the BITE memory and can be read on either MCDU in the maintenance mode through the DMC menu .

C. N1 lIMIT
The N1 limit displayed value is the N1 limit value delivered by ECU of the engine for which the N1THR is the greatest or the N1 LIM of ECU linked to the fastest engine if N1.1 - N1.2 > 0,2% or the N1 LIM of ECU remaining valid after one ECU has failed or the N1 LIM of ECU belonging to the engine which is still running after an engine failure. On the ground when both engines are stopped, the displayed N1 limit value is that one delivered by the ECU of the engine the throttle control lever of which is in the most advanced position.
The N1 limit displayed value is the N1 limit value delivered by EEC of the engine for which the N1THR is the greatest or the N1 LIM of EEC linked to the fastest engine if N1.1 - N1.2 > 0,2% or the N1 LIM of EEC remaining valid after one EEC has failed or the N1 LIM of EEC belonging to the engine which is still running after an engine failure. On the ground when both engines are stopped, the displayed N1 limit value is that one delivered by the EEC of the engine the throttle control lever of which is in the most advanced position.

D. N1 LIM MODE
The N1 LIM MODE is the mode in which the above N1 LIMIT value is computed. Obviously , the displayed N1 limit mode is that one delivered by the ECU which is selected to display the N1 limit value .

These modes are selected according to the throttle control lever position (the position which is the most advanced is taken into account).
Detents (mechanical notches) are associated to the mode selection.
In flexible take off mode, the value of the flexible TAT take off temperature, which is entered by the crew through the MCDUs, is displayed in cyan color next to the N1 LIM value.
The indication shows for instance:
In flexible take off mode, the value of the flexible TAT take off temperature, which is entered by the crew through the MCDUs, is displayed in cyan color next to the N1 LIM value.
The digits are replaced by cyan dashes if the Static Air Temperature minus 10°C is strictly superior to the Flex Temperature.
The indication shows for instance:
In flexible take off mode, the value of the flexible TAT take off temperature, which is entered by the crew through the MCDUs, is displayed in cyan color next to the N1 LIM value.It is displayed under following conditions:
- N1 limit mode display selection is valid.
- Flex mode activated.

E. N1 MAX
The N1 MAX value is displayed in analog form by means of a thick amber mark across the N1 scale.
N1 MAX is the N1 LIMIT value corresponding to the full forward position of the throttle control lever.

F. N1 REFERENCE (N1 throttle)
The N1 reference symbol (small white circle) represents the N1 predictive value for each engine, in manual mode (the N1 value that would be reached or will be reached in manual control after stabilization, depending on the throttle control lever position).
The N1 reference symbol (small cyan circle) represents the N1 predictive value for each engine, in manual mode (the N1 value that would be reached or will be reached in manual control after stabilization, depending on the throttle control lever position).

G. N1 COMMAND
The N1 CMD is displayed in analog form by means of a cyan arc of a circle joining the N1 actual needle to the N1 CMD value. Therefore, when the N1 speed is stabilized, this symbol is reduced to a mark which is covered by the N1 actual needle.
The N1 CMD is displayed only with the A/THR engaged.
The N1 CMD is displayed in analog form by means of four green arcs of circle joining the N1 actual needle to the N1 command needle.
The N1 CMD is displayed only with the A/THR engaged, and the N1 CMD value valid, and engine running.

H. N1 Trend
In addition a green triangle next to the N1 CMD value enhances the N1 direction and stays displayed even when the two values are very close; it disappears when the N1 value has reached the N1 CMD value.
It is displayed only if engine is running.

I. N1 degraded data
In case of failure of the normal N1 measurement system from the FWC, the EEC computes a theoretical value taking into account the other engine parameters. In this case the last digit of N1 is dashed with two horizontal amber lines.

J. N2 INDICATION
The N2 indications are displayed in the digital form only. 100% N2 correspond to 14460 RPM . Should N2 actual exceeds the N2 red line value , a red cross appears next to the digital indication to warn the pilot that an N2 exceeding has occurred. This red cross disappears only after a new take off or after a maintenance action through the MCDU . Like the N1, the N2 exceeding values are stored in the BITE memory and available on the MCDU through a maintenance menu.

M. COOLING indication or READY FOR START indication

Engine Parameter Display ** ON A/C NOT FOR ALL

COOLING message is displayed near Fuel Flow indication:

In green pulsing when the engine cooling is active.
In steady green when COOLING needed is active and the engine cooling is inactive.

Engine cooling counter is displayed below the COOLING message in green when COOLING needed is active and cooling counter value is valid.
Otherwise nothing is displayed.

Engine Parameter Display ** ON A/C NOT FOR ALL

The upper ECAM shows one of the two messages near the N2 indications:

READY FOR START
COOLING.

The READY FOR START message comes into view in the conditions that follow:

N2 of the other engine is more than 50 per cent.
The starter air valve of the other engine is set to the closed position.
The Ready-for-Start function is armed for the two engines.
The master lever of the engine is set to OFF.
The aircraft is on the ground.
The READY FOR START message has the priority on the COOLING message and the COOLING counter. When the READY FOR START message comes into view, the COOLING message and the COOLING counter go out of view.

The READY FOR START message goes out of view in the conditions that follow:

The master lever of the engine is set to ON, or
The engine is in operation during more than 90 seconds, or
The other engine prevents the start, or
The AVAIL message of the other engine goes out of view.

The COOLING message comes into view in green when:

The conditions necessary to cool the engine are present, or
The engine cooling is in operation.

The engine COOLING counter comes into view in green when:
The conditions necessary to cool the engine are present, and
The cooling counter value is correct.
In other conditions, there is no indication.

The engine COOLING counter is shown below the COOLING message.

N. REVERSE INDICATIONS

Reverse and failure indication ** ON A/C NOT FOR ALL

An amber REV indication comes into view at the middle of the N1 dial when at least one reverser blocker door is unstowed or unlocked. If this occurs in flight, the REV indication first flashes for 9 s and then remains steady.
This indication changes to green color when the fan reverser blocker doors are fully deployed and when the reverse thrust can be applied.

Reverse and failure indication ** ON A/C NOT FOR ALL

Normal conditions (the aircraft is on the ground and Reverse mode is selected):
An amber "REV" indication in a grey box comes into view above the N1 digital indication, if:

At least one reverse cowl is unstowed, and
No thrust reverser failure is detected.

This indication becomes green when all the reverser cowls are deployed.

Abnormal conditions:
When the aircraft is on the ground, an amber "REV" indication in a grey box comes into view, if:

Reverse mode is not selected and the two reversers are deployed, or
At least one reverser cowl is not stowed and no thrust reverser failure is detected.

If this occurs in flight, the "REV" indication in the grey box first flashes for 9 seconds and then remains steady, if:

At least one reverser cowl is not stowed and no thrust reverser failure is detected, or
The two reversers are deployed.

An amber "XX" indication is shown above the N1 digital indication, if:

The stowed and locked signals, or
The fully deployed signals, or
The not stowed signals of the thrust reverser doors are not valid.

In other conditions, nothing is shown.

O. AVAIL indication
The AVAIL indication is located at the same place as the REV indication. This indicates that the engine relight is successful. In flight a green message AVAIL keeps pulsing until the throttle lever angle is greater than 8° (confirmed 5s), or until 60s have elapsed. On ground a green message stands until the throttle lever angle is greater 8° (confirmed 5s), or until 10s have elapsed.
The AVAIL indication can be displayed only if the option is activated by pin- programming.

Engine relight ** ON A/C NOT FOR ALL

P. FAILURE INFORMATION

Reverse and failure indication ** ON A/C NOT FOR ALL

In case of failure of any parameter, the associated indication is replaced by amber crosses. When this parameter is either N1 or EGT, the scale support is also presented in amber color.

Q. MONITORING OF THE RELEVANT DISPLAY OF THE ENGINE PARAMETERS
The N1, N2, EGT and FF (Fuel Flow) indications of the two engines are monitored internally and externally.
The Display Management Computer (DMC) compares the N1 signal received from Electronic Control Unit 1 (ECU) with the feedback signal that shows the position of the N1 needle.
To make sure that the engine 2 monitoring process is different, the DMC compares the N1 signal from ECU2 with the feedback signal that shows the N1 digital value.
The DMC also compares the EGT parameter indications, but with the position of the engine-2 EGT needle and the engine-1 EGT digital-feedback-value.
For the N2 and FF parameters, the DMC compares the direct signal from the ECU with the shown digital value (alpha-N signature process).
If it finds a discrepancy, a CHECK EWD amber message comes into view on the upper center display of the PFD.
The Flight Warning Computer (FWC)s also monitor the feedback signals externally (related to the shown values) and the signals that the FWCs receive directly from the ECUs.
If there is a discrepancy, for one or more parameters, the FWCs cause:

A single chime
A master caution light
A message on the upper ECAM DU : ENG1(2) N1(N2/EGT/FF) DISCREPANCY.

There is a safety mechanism in the Electronic Instrument System (EIS) to monitor the engine parameter N1, N2, EGT and FF (Fuel Flow) indications of the two engines.
The EIS compares the shown digital/analog value with the signal received from the EECs. If it finds a discrepancy, a CHECK EWD amber message is shown on the upper center display of the PFD (it flashes nine seconds and then stays stable).
The Flight Warning Computer (FWC)s also monitor the feedback signals externally (related to the shown values) and the signals that the FWCs receive directly from from the EEC's.

The displayed main engine parameters (N1, EGT, FF) are monitored by the EIS.
For N1 and EGT, each DU compares the signals received from the ECU with the feedback signals which reflect the displayed position of the needle and the digital value.
For the Fuel Flow parameter, the DU compares the direct signal from the ECU with the displayed digital value.
The feedback messages is displayed above the FOB indication:
CHECK CAPT PFD (amber)
CHECK F/O PFD
CHECK CAPT ND
CHECK F/O ND
CHECK SD
In case of detected discrepancy, to indicate a DU failure to the crew.
A warning message is also generated by the FWC.

R. System Feedback Message
The safety mechanism implemented in the EIS, also monitor the critical parameters displayed on every image. When a discrepancy between the signal sent by the sensors and the data actually displayed, an amber message is displayed on the EWD depending on the image which is monitored. It flashes 9s then remains steady (the display of these messages is also feed-backed):
On the first line:

CHECK CAPT PFD
CHECK F/O PFD On the second line:
CHECK CAPT ND
CHECK F/O ND
CHECK SD
Reverse and failure indication ** ON A/C NOT FOR ALL

Also when the software standard of an item of equipment, part of the EIS does not match the other items a system message is displayed at the same place:
DISPLAY SYSTEM VERSION INCONSISTENCY (amber)
And, when the DU is no more monitored the following message is displayed:
DU NOT MONITORED (amber). All these messages flash for 9s then are steady.

NOTE: (1): The processing of the engine 1 and 2 input parameters is independent.
(2): The values of the N1, N2, EGT red lines and transitory overlimit values are stored in 2 independent tables, one for each engine type. The same applies for the advisory thresholds as regards to the oil pressure, temperature, quantity.
The N1, N2, EGT red lines and transitory overlimit values are sent to the FWCs through the DMC general high speed output bus.

(1) Switching test
In maintenance mode a magenta EWD1 (2 or 3) message appears above the warning mode. It shows the digital link between the DMC and the DU is valid.

The alpha floor function is activated in case of excessive angle-of-attack and consists in setting engine thrust to TO/GA configuration. It is generated by the FAC and a signal is transmitted to the DMC for display of the A FLOOR message in amber in the upper part of the engine parameter area (FCU label 270 bit 23).

B. Idle

Flap and Slat Position Indication ** ON A/C NOT FOR ALL

A. Operation
In clean configuration, a grey wing shaped symbol is presented. When a position different from the clean configuration is selected, a scale appears composed of white dots and of a FLAP indication. This scale features the different possible positions of the slats and the flaps. The actual position is indicated by green indexes moving in either direction according to the movement of the surfaces : extension or retraction.
The selected position is indicated by cyan indexes pointing to the next target position of the slats and flaps. At the same time the FLAP indication becomes cyan and a cyan number gives the selected position in accordance with the reference numbers which are written on the flaps/slats control panel.
When the target position is reached, the cyan indexes disappear and the FLAP message comes back to the white color whereas the number becomes green.
This number changes to the FULL message when the slats and flaps are fully extended.

B. Abnormal Operation
In case of slats or flaps jamming, the dedicated index changes in color from green to amber. In addition an S or an F indication appears depending on the concerned surface.
When the stopping of the surfaces is due to the fact that the wing tip brakes have been applied (for example detection of an asymmetrical condition) the S-LOCKED or F-LOCKED message is displayed.

Flap and slat abnormal operation ** ON A/C NOT FOR ALL

If the slats or flaps position information coming from the FWCs or the SDACs is unavailable, an amber XX flag appears positioned below the S or F indication depending on the concerned surface. The corresponding scale (slat part or flap part) goes out of view.

Display unit lower section assignment ** ON A/C NOT FOR ALL

A. Operation
The lower part of the display provides the pilot with either warning/ caution or memo messages. Special memos or check-list as landing memo or take-off memo are provided on this display.
At last, special messages such as STS, ADV or overflow arrow can be also displayed.
The following description explains in general the partitioning and the use of the different zones. The description and the various texts which are delivered by the FWC for display on the upper ECAM DU is given in the chapter 315100 .

B. Partitioning
The lower part is divided in 2 zones separated by a grey stripe. The left zone contains 7 lines of 24 characters whereas the right one contains 7 lines of 12 characters.

The lower part is divided in 2 zones separated by a grey stripe. The left zone contains 8 lines of 27 characters whereas the right one contains 8 lines of 14 characters.

C. Warning Messages
These messages are displayed first on the left zone and have priority on the left memo messages. If the number of lines of the whole text of the warning/caution messages exceeds 7, the titles of the not shown failures are written on the right zone and they have priority over the right memo messages displayed . The secondary failures are displayed on the right zone and they have priority over right memo messages .

D. Overflow Indication
When the text of warning/caution messages exceeds the capacity of the display, a green overflow arrow appears below the grey stripe. This arrow concerns only warning messages and does not deal with memo messages.
This arrow remains displayed on the screen as long as there are texts still waiting for display.

E. Memo Messages
They are shared in two lists, on the left and right parts. They are displayed when no warnings/caution messages are presented. As previously mentioned, the memo messages can be either A/C system functions which are selected (LDG LT,...) or special check-lists like take-off memo or landing memo.

F. STS And ADV Messages
Added to the overflow indication, two draw attention symbols may appear on the display:

STS
It appears below the grey ribbon at the same location as the overflow arrow provided that this one is away. This message indicates to the pilot that the status page is no more empty.
ADV
It appears only in single display configuration to signal to the pilot that a parameter drifts in an A/C system. As the corresponding system page cannot be displayed on the lower ECAM display unit, the pilot has to fetch the information on the ECAM control panel : the associated pushbutton switch flashes to indicate which system is concerned.

Added to the overflow indication, two draw attention symbols may appear on the display:

STS
It appears below the grey ribbon at the same location as the overflow arrow provided that this one is away. This message indicates to the pilot that the status page is no more empty.
ADV
It appears in normal and single display configuration to signal to the pilot that a parameter drifts in an A/C system. As the corresponding system page cannot be displayed on the lower ECAM display unit, the pilot has to fetch the information on the ECAM control panel : the associated pushbutton switch flashes to indicate which system is concerned.

14. Acquisition and Wiring

A. ECU or EEC (FADEC System)
Each engine control unit issues 4 output buses which always convey the same data 2 by 2. Each ECU is fully redundant; in case of failure of channel A, channel B takes over.
Each DMC receives and processes one 'A' bus and one 'B' bus from each engine ECU.
The DMCs take the needed parameters preferably on the bus corresponding to the channel in control (label 275, bits 26 or 27).
If a parameter is invalid on one bus, the DMC takes it on the other bus. If this parameter is available neither on the bus 'A' nor the bus 'B' the corresponding indication is either flagged (XX) or cleared, depending on the nature of the parameter.

NOTE: There is no ECUWVALID signal. Each parameter is considered separately.

If a parameter is invalid on one bus, the DMC takes it on the other bus. If this parameter is available neither on the bus 'A' nor the bus 'B' the corresponding indication is either flagged (XX) or cleared, depending on the nature of the parameter.

NOTE: EEC bus validity criteria:
There is no signal giving the validity of the entire bus. Each parameter is considered separately. If a parameter is invalid on one bus, the other bus is used. If this parameter is available neither on bus A nor on bus B, the corresponding indication is either flagged or removed.

B. FQI
The FQI issues 4 buses, FQI-1A, 1B, 2A, 2B.
DMC1 acquires 1A and 2A
DMC3 acquires 1A and 2B
DMC2 acquires 1B and 2B.
Each DMC uses preferably the FQI-1 (A or B) bus parameters.
If the FQIS CHANNEL SUPERIORITY signal (label 276 bit 13 of both FQI channels) requests the switching to the FQI-2 bus, the DMCs switches to this FQI-2 bus.
However, the DMC keeps using a given FQI-X bus only if this bus is valid.
A given FQI-X bus is valid only if all parameters used by the DMC are valid.
If the 2 FQI-1 and 2 buses are invalid, the DMC switches permanently from one to the other until finding a valid one. Meanwhile the fuel quantity parameters are flagged (XX) on the ECAM E/W image.
