Question

What is the relation betweenpower and airspeed for climb gradient?

(a) Power increases with increase in airspeed

(b) Power decreases with increase in airspeed

(c) Power increases with decrease in airspeed

(d) Power is unaffected by the airspeed

I have been asked this question in a job interview.

I need to ask this question from Climb and Descent Performance with Power-Producing Engines topic in division Climb and Descent Performance of Aircraft Performance

Answer 1

Right choice is (c) Power increases with decrease in airspeed

For explanation: 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.
