Hi MB2002,
how can you have an airplane with two different FMAs?
By design, it is necessary for each pilot to monitor his respective autopilot during CATIII etc. approaches. So the onside FMA indicates what mode that independent AP is computing. (Like 1 FD 2 compared with 1 FD 1) If one side said "FLARE" before the "One hundred" call from PNF - then you'd know there was something wrong with this picture, compare FMAs then GA.
why the APU GEN is not capable of achieving the electrical split when it comes in line instead of a failed engine GEN?
I don't understand that one because I still can't see why the electrics aren't considered split.
(In the early days on L1011, the APU did not qualify as an adequate electrical source, so with an engine elec geny out, we were downgraded. Sometime later, the APU geny was considered to be satisfactory and approved - then we could do CAT IIIB NO DH even with an engine geny out but with the APU on line.) PFM
