777 APU & flight control questions
Hi all,
A couple of 777 questions for those with the knowledge.
1. When selecting an APU to Pack takeoff in the fms, why is only one pack powered? If it can supply both at the gate, what’s the logic for only one during takeoff, and would a crew manually configure the system for the APU to supply both packs on a hot day?
2. When doing the flight control check, it why do you not select the flight control synoptic page? How do you know the surfaces are moving as required?
