Top panel annunciators

There are five illuminable annunciators across the top of the MCDU front panel of which one is spare and not utilized. The spare annunciator is unlabeled but it contains an amber light.
(a) FM1 and FM2

The FM failure annunciators at the top of the MCDU indicate when a FM failure occurs.
The FM1 failure light on MCDU1 and/or MCDU2 comes on (amber) if FM1 is the selected FM, the MCDU BRT knob is at ON and the FM1 subsystem identifier word (label 172) is not received for three seconds by the MCDU.
Likewise, the FM2 failure light on MCDU1 and /or MCDU2 comes on (amber) if FM2 is the selected FM, the MCDU BRT knob is at ON and the FM2 subsystem identifier word is not received for three seconds by the MCDU.
The corresponding FM failure annunciator on MCDU3 comes on only if MCDU3 operates as a backup to MCDU1 or MCDU2. It comes on only in the context of the failed MCDU selected FM.
Additionally, a MCDU never has both its FM failure annunciators on. The FM failure annunciators are off when an identifier word is received from the appropriate FM.
(b) RDY

This annunciator comes on (green) when the MCDU passes its long-term power up or power off reset test after its BRT knob is turned to OFF.
(c) IND

This annunciator comes on (amber) when the selected FM detects an independent operation (loss of dual mode) while both FMs are healthy. If either FM is failed, the annunciator is not on, regardless of the state of the intersystem bus.

A. Do a check for a maintenance message on the Post Flight Report (PFR):

(1) If the AFS test gives one or several maintenance messages:

- do the trouble shooting procedure related to the maintenance message(s).

(2) If there is no message, no maintenance action is necessary.

这样会有依赖性的，发现问题，看手册研究，这样下次遇到就能正确的处理

FMGC或者MCDU问题，一般是MCDU的问题，只要数据能交联，不影响可以保留放行

恩那就是可以~关键怎么认证是否交联
