Hi all:
I recently have had a couple of flights in a very small plane (8 seats, including pilot and empty seat next to him/her). Not sure the make, but there are overhead switches for the fuel pumps. I was watching the pilot fly as I was in the 2nd row, and during takeoff and landing, both pilots engaged the fuel pumps. However they left them disengaged during flight.
Can anyone explain to me (an engineer) why this is? Does the engine gravity feed?
