__________________
A. Do the Operational Test of the LAND CAT III Capability (Ref. AMM TASK 22-97-00-710-001).
4. Fault Isolation
_______________
A. If the test is good:
(1) Check the FG BITE (Trouble Shooting Data) of the previous flight:
- retrieve a snapshot with event 7 from MON channel,
- check the 2nd digit of the Word 2 (-X--).
(a) if this digit is even (0,2,4,6,8,A,C,E):
- replace the BTC-1 (11XU1), (Ref. AMM TASK 24-22-55-000-001) and (Ref. AMM TASK 24-22-55-400-002)
- if the fault persits, replace the BTC-2 (11XU2), (Ref. AMM TASK 24-22-55-000-001) and (Ref. AMM TASK 24-22-55-400-002)
- if the fault still persists, replace the CNTOR-DC NORM BUS 2 SWITCHING (1PC2), (Ref. AMM TASK 24-35-55-000-001) and (Ref. AMM TASK 24-35-55-400-001).

(b) If this digit is odd:
- no further action is required.
B. If the test is not good:
- If there is a message, do the trouble shooting procedure related to the maintenance message.

B. If the message is still present in the scratchpad:
- perform a C/B reset (10CA1 and 10CA2) of both FMGCs.
(1) If the message disappears, no maintenance action is necessary.
(2) If the fault continues:
(a) Do a check of:
- the NDB cycle is the same for the two FMGCs.
- the P/N is the same for the two FMGCs.
- the wiring of the pin programming of the two FMGCs (Ref. AWM 22-85-30), (Ref. AWM 22-85-31), (Ref. AWM 22-85-36) and (Ref. AWM 22-85-37) 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320 Trouble Shooting Manual 排故手冊 AUTO FLIGHT 自動飛行2(103)
