4. TABLE 4

A. WTB RESET Page

(1) When the SFCCμs have detected a critical system failure, applicacation of the WTB is set to arrest the system/transmission in a fail- safe condition. Locked E/W is simultaneously triggered to inform the flight crew. The setting of the WTB is latched inside the SFCC (by means of latching relays keeping energized the WTB solenoid even if SFCC is not energized). The WTB reset function allows to reset the relays.

(2) When on the submenu pages SFCC-(1) (2) TEST/RESET the Line Key "1R" "WTB-RESET" is pressed, the named SFCC transmits the following page to the CFDS.

NOTE: X can be PWR UP TEST or SFCC-TEST.

The available test result information of lane A/B is shown in a coded hexadecimal form.
Each lane indicates 48 bytes which are used to get information about each specific subtest.

NOTE: BITE TEST result decoding requires Airbus or SFCC manufacturer assistance unless you will find a decoding in a TSM-Task in TSM 27-51-00 PB 201.
You will also find the decoding of the coded information in the related CMM.

(15) If the SFCC-TEST is done and the SFCC periphery is not complete, an SFCC-TEST result page is transmitted to the CFDS to indicate the status. SLAT or FLAP is added to the title.

7. TABLE 7

A. SFCC Interactive MCDU Menu Management

(1) The structure of the SFCC interactive MCDU menu is shown as follows.

SFCC Menu Access

SFCC Access Menu

B. Several features/functions are essential to do the flap troubleshooting and to obtain data on fault identified by the system or status on the system.

(1) CFDS PAGES - SYSTEM STATUS
All maintenance messages (class 1, 2 and 3) related to all faults detected in real time by the system will be shown during the SYSTEM STATUS. In order to indicate a transient fault to the operator, the maintenance messages, automatically shown in SYSTEM STATUS, are only erased when exiting from the function.
CLASS 1
Faults which have an operational cockpit event. The status given by these faults are covered by the MMEL. Faults are present in the PFR.
CLASS 2
Faults which do not have consequence on the system operating conditions. Information of CLASS 2 faults is done through the ECAM MAINTENANCE STATUS. It is considered by repairing them before the next scheduled maintenance task, that the dispatch is significantly increased. CLASS 2 faults are shown in the PFR.
CLASS 3
Faults which have no consequence on the system operating conditions and the crew is not aware of them. Faults are not shown in the PFR but are available in the CLASS 3 FAULTS menu.

(2) CFDS PAGES - LAST LEG REPORT
This section presents all messages sent to the CFDIU. The SFCC does not make any correlation as opposed to CFDIU which determines the identifiers. This is a simplified backup of the printed PFR.

(3) CFDS PAGES - PREVIOUS LEGS REPORT
The previous legs report function is the history of the LAST LEG REPORT of the system limited to 64 flights.

(4) On ground fault
The MCDU displays the faults stored in the "on ground failure memory" (generally limited to the 3 last faults recorded). But if no failures are stored, the MCDU shows the "NO FAULTS" message. This function shows on ground the class 1,2 and 3 maintenance messages related to new faults detected on ground and which are therefore not recorded in the PFR. The faults detected during flight and still present on ground are in the PFR/CLASS3 FAULTS and not in the ON GROUND FAULTS (except class 3 faults). This function presents the history of these faults since the aircraft landed up to the next take-off.

(5) CFDS PAGES - CLASS 3 FAULTS
All class 3 maintenance messages corresponding to the selected system are grouped under this section.

(6) Flap SYSTEM DATA - PPU
The flap data is refreshed every 5 seconds with updated data.

Flap System Data PPU

NOTE: "272.3" represents the decimal value of the synchro angles. "C1A" represents the hexadecimal value of the same data.

C. System Tests

(1) WTB/POB Test
This test allows to check the engagement and performance of the WTB and POB.

Please refer to AMM Task 27-51-00-710-001-A, Operational Test of the Wing Tip Brake and Pressure Off Brake.

(2) WTB RESET (please also refer to table 5)

Please refer to AMM Task 27-50-00-869-006-A, Reset of the Wing Tip Brake of the Flap System on the Ground.

(3) SFCC Test (please also refer to table 7)

Please refer to AMM Task 27-51-00-740-002-A, BITE Test of the Slat and Flap Control Computers (Flap System).

D. Other features might help to further investigate a fault, but will only be used on a case by case review and will require assistance of AIRBUS or SFCC manufacturer for interpretation.

(1) System Data > X-Link Input (please also refer to table 2)

(2) System Data > Discrete Input (please also refer to table 6)

(3) System Data > ARINC 429 Input Status (please also refer to table 6)

(4) SFFC Test Failure Report (please also refer to table 7)

E. Troubleshooting Data

(1) The "TROUBLE SHOOTING DATA" item provides additional data about the failures (all classes) recorded during the last and previous legs. The prompt adjacent to a message gives access to the corresponding snapshot.
