What is the relation between thrust power and true airspeed?(a) Thrust power increases with increase in true airspeed(b) Thrust power decreases with increase in true airspeed(c) Thrust power increases with decrease in true airspeed(d) Thrust power is independent of true airspeedI have been asked this question in an online interview.Asked question is from Climb and Descent Performance with Thrust-Producing Engines in section Climb and Descent Performance of Aircraft Performance

Answer»

Correct option is (a) Thrust POWER increases with increase in true airspeed

Explanation: Thrust power increases with increase in true airspeed.The best rate of CLIMB occurs when the excess thrust power (FNV) is maximum than the DRAG power (DV). As the ideal power increases linearly with true airspeed the best gradient of climb is predicted to be at an airspeed greater than minimum drag speed.
