e) she had an FCPC1 reset when a-d conditions were still valid.
Takata,
I beg to differ. I think this is at least controversial.
And I remeber you saying something about failed engines. Maybe that's why Will Fraser is coming up with that AD now.

I understand your point. I thought realignment could be
done in flight if you had the other two IRs ok.
Of course if you don't have any NAV information to realign from you will have to land and do it on the ground anyway.
But remember that if a pitch down ever occurred - something equally controversial - the crew would be put in extreme
stress - not understanding what really was going on.
Let's also recall that between 2:11 and 2:12 (2:13 ?) zulu that night something happened that caused a brief interruption in the ACARS message transmission.
