R A. Deactivation of the Slat and Flap Control Computer (SFCC) N0. 2 Flap R Channel R (1) When you do this procedure, it may be necessary to open circuit
R breaker 12CV. R (2) Do this procedure: -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the MCDU:
-get access to the Flight Controls (F/CTL) SYSTEM REPORT/TEST page (Ref. TASK 31-32-00-860-001).
R - push in the key adjacent to < R SFCC 1.
-push in the key adjacent to SYSTEM STATUS FLP >.
R - push the key adjacent to < RETURN until the SYSTEM REPORT/TEST F/CTL page is shown.
R - push in the key adjacent to < R SFCC 2.
-push in the key adjacent to SYSTEM STATUS FLP >.
On the MCDU:
-
the F/CTL SYSTEM REPORT TEST PAGE isshown.
-
the SFCC 1 menu is shown.
-< NO FAULTS > is shown except FLP 1NO SFCC 2 DATA.
-
the SFCC 2 menu is shown.
-
the SYSTEM STATUS FLP page is shown.
-------------------------------------------------------------------------------
ACTION RESULT -------------------------------------------------------------------------------
-
if FLP SYS LOCKED is shown,
because of an electrical fault,
reset the wing tip brakes of
the flap system with the SFCC 2
(Ref. TASK 27-50-00-869-006).
-
if the procedure to reset the - the 28V power supply from SFCC 2 to wing tip brakes (of the flap the wing tip brakes is disconnected. system) with the SFCC 2 cannot be completed satisfactorily, open the circuit breaker 12CV.
-push in the key adjacent to <
RETURN until the F/CTL SYSTEM
REPORT TEST page is shown.

C. Aircraft Maintenance Configuration.
(1) Make sure that the Green, Yellow and Blue hydraulic systems are pressurized (Ref. TASK 29-10-00-863-001) (Ref. TASK 29-10-00-863-002) (Ref. TASK 29-10-00-863-003).
Subtask 27-51-00-040-055
R D. Deactivation of the SFCC No. 2 Flap Channel (Continued)
R (1) Do a check of the SFCC No. 1 flap wing tip brake as follows: -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1.
Set the Slat and Flap control lever to the position 3.
2.
On the MCDU:
-push the line key < SFCC 1.
R 3. Push the NEXT PAGE button. R
4. Push the line key TEST/RESET FLP >.
R 5. Push the line key < WTB/POB TEST. R
6. Push the line key < CONTINUE.
R 7. Push the line key < START TEST. R
NOTE : If the line key < START
____ TEST is not shown, do the instructions the MCDU shows.
R R The slats and flaps move to theposition 3.
On the MCDU:
-
the MCDU shows the SFCC 1 menu.
-
the MCDU shows the next page of the SFCC 1 menu.
-
the MCDU shows the SFCC 1 FLAPTEST/RESET menu.
-
the MCDU shows the SFCC 1 FLAP WTB/POB TEST instructions.
-
the MCDU shows the next page of the SFCC 1 FLAP WTB/POB TEST instructions.
-
the MCDU shows that the FLAP WTB/POB TEST is IN PROGRESS.
-
the MCDU shows in less than 2 minutes: SFCC 1 PERFORMED NO FAULTS RESULT NOT STORED
-if the MCDU shows: PERFORMED UNSUCCESSFULLY - TEST INVALID,
