The range and endurance are proportional to which of the following factors?

(a) fuel flow

(b) net thrust

(c) bypass ratio

(d) airspeed

This question was posed to me in an internship interview.

My doubt stems from Cruising Performance topic in chapter Cruising Performance of Aircraft Performance

Best answer
The correct option is (b) net thrust

Easy explanation: The range and endurance are proportional only to net thrust. The fuel flow laws proved to be a constant idealized laws. Though fuel flow laws cannot describe all the characteristics of the engine they are proved to be a constant idealized laws.
