Question

There are two ways of aircraft descend of an aircraft.

(a) True

(b) False

The question was asked in semester exam.

This is a very interesting question from Descent Performance in Aircraft Operations in chapter Climb and Descent Performance of Aircraft Performance

Answer 1

Correct option is (a) True

The best explanation: The aircraft will descend if the propulsive thrust is less than the airframe drag. The descend flight path can be varied from a shallow descent to a very steep descent either by reducing the engine thrust or by increasing airframe drag.
