(a) thrust-producing and power producing

(b) weight-producing and power producing

(c) thrust-producing and weight producing

(d) thrust-producing, power producing and weight producing

I got this question in examination.

This question is from Thrust Producing Power Plant topic in division Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

Correct choice is (a) thrust-producing and power producing

For explanation I would say: The two forms of powerplant used in aircraft propulsion are thrust-producing and power producing. Thrust-producing engines include turbojet, turbofan and rocket while power producing engines are get engine and piston engine.
