Question

The best climb gradient is attained by flying at airspeeds less than the minimum power speeds.

(a) True

(b) False

This question was addressed to me in a national level competition.

My query is from Climb and Descent Performance with Power-Producing Engines topic in section Climb and Descent Performance of Aircraft Performance

Answer 1

The correct choice is (a) True

To explain I would say: The relation between power and airspeed for climb gradient is that the power increases with decrease in airspeed for maximum climb gradient. The best climb gradient is attained by flying at airspeeds less than the minimum power speeds.
