For check Airman,
You forgot the world's worst oral question, "How does the recirculation fan work on the 757 versus the 767 and when does it operate and not operate?"
My response that got me in a bit of trouble was, "It operates all the time it is supposed to operate unless it is broken or malfunctioning and then we go into the log, find the proper maintenance code and write it up, right?"
I'd have given you full points for that
So what about load shedding, engine start, fire in the hold?? There are times when the re-circ fans switch off because they are supposed to!
To enter the door debate. I am a licenced a/c engineer rated on the 767 and I have yet to work on a 767 that does NOT have at least 1 electrically operated pax door. There are switches under the exterior handle and on the FAP for the relevant doors.
