A320 Loss of F/Ds
Hi,
I just wanted to ask you guys a question that my instructor asked me.
What are failures that causes the loss of F/Ds?
I canīt get the logic of F/D, do I need to check every abn procedure from the fcom?
thanks

Flight directors receive information from their respective FMGCs so a Dual FMGC failure results in the loss of both FD1 and FD2.
AUTO FLT FCU 1 + FCU 2 FAULT results in the loss of both FD1 and FD2.
In the Emergency Electrical Configuration, AP, ATHR and FD are lost.

The question per se is totally meaningless. Have you tried asking him what is the benefit of knowing all the circumstances that will lead to the loss of FDs rather than knowing what is the impact of losing FDs in the various flight phases ?

Speed Protection.If you are flying without AP and don't follow FD then if the speed exceeds VFE or decrease below VLS the FDs are removed and ATHR changes to speed mode, the managed speed target becomes selected and ATHR maintains the speed.
But loss of FDs in abnormal conditions you will have to go through Abnormal procedures.

We all get old and eventually start developing memory gaps. Next time he asks you, you ask him what he had for breakfast.

Exactly. If it happens, it happens. What's more important is how you deal with it.

Perhaps the questioner wanted the OP to understand the generator fmgc logic and the fact that the apu gen cannot recover the landing capability.

Magenta over Blue; One Flight Director 2.
There's a totaled 320 sitting on the field in PHL that lies testament to the fact nursery rhymes can save the day....

No nursery rhyme was required for that accident.THRUST NOT SET message check the Thrust lever position if not set in Flex set it. If in Flex hit TOGA and continue or close thrust levers to idle, go back and find out.
