The information in the 747 maintenance training manual states: "Go around mode is engaged when there are these conditions - 1, autothrottle armed. 2, airplane in the air. 3, glideslope captured or flaps not zero. 4, thrust limit mode not T/O.
Resurrecting an old message thread...
I have been unable to find (in the 747-400 engineering manuals) any data paths from the Flap Control Units to the Flight Control Units which contain leading edge flap position information....
only inboard trailing edge flap position. Ref wiring schematic 27-51-04 Sh 2
How can the aircraft go into GA mode at Flaps 1 if LE Flap information is not available to the FMC? Similarly I only see inboard TE Flap data going to the FMC for thrust mode limit (G/A). The FMC generates the modes on EICAS.
Tech gurus?
Thanks
