For aircraft that have a boost pump:

What is the reason for having the boost pump in the "on" position when performing maneuvers (chandelle, lazy 8, eights on pylons)?

    That’s not universally true, Dan. There are aircraft where the electric fuel pump is used only for emergencies.. You won’t use the boost pump for maneuvers in those. At the opposite end, there are aircraft in which it’s recommended to have the boost pump on all the time.

    What you will find is that aircraft that have the boost pump on for take offs and landings typically also have it on for maneuvers. For similar reasons, so consult the POH for the aircraft in question.
