At what condition does maximum endurance occur for propeller aircraft?

Question

At minimum fuel flow

At minimum V/F

At minimum throttle setting

At maximum throttle setting

Answer 1

Maximum endurance for propeller aircraft occurs at minimum fuel flow. This condition allows the aircraft to stay aloft for the longest period of time because it minimizes the amount of fuel consumed per hour of flight. While other factors like airspeed and power settings are important, the key focus for maximizing endurance is to operate at the point where fuel consumption is at its lowest for a given amount of lift and drag.
