MEL A320 Question
 

If let’s say, FMGC2 is inop, is it necessary to differ all the secondary failures, such as autopilot and flight director?
thank you!

You are correct that any 'refer to' note in the Mi needs to be tracked down and complied with.

For your example case it kind of makes sense, some of the others are not so obvious. However that is the correct procedure to handle the book.

Good question to explore from the desk, before the day actually comes and you need to act, BTW. :ok:

Hi FlightDetent would you happen to have any sort of documentation about this? We are having this discussion at my outfit right now and it would be really helpful to have any info that could help us to clear this up. Thank you

At my outfit, the MEL for the primary failure tells us which other MEL items to apply for secondary “failures”.

This is what the MEL says . The blue lines are hyperlinks to the relevant entries of the other failed kit.

Discussions among the line pilots must be cleared with the Fleet office and Technical pilot.

If the office is not ready to issue resolute guidance (such as differing points of view compared to the NAA's) they better seek guidance from their Airbus liaison and CAMO team.

The MEL has a How to Use chapter which tells you precisely on how it is to be handled.
