Question

Which of the following is correct according to power producing engines?

(a) Airspeed for climb is high than for optimum climb gradient

(b) Airspeed for climb is less than for optimum climb gradient

(c) Airspeed for climb is equal to optimum climb gradient

(d) Airspeed for climb is equal to maximum climb gradient

This question was posed to me by my school teacher while I was bunking the class.

My doubt stems from Climb Gradient in division Climb and Descent Performance of Aircraft Performance

Answer 1

Right answer is (a) Airspeed for climb is high than for optimum climb gradient

Easy explanation: The airspeed for climb is high than for optimum climb gradient in the case of power producing engines. The airspeed chosen for after take-off climb should be same as for that of maximum gradient. The safeguard path has a gradient of 2%. The safeguard distance extends from the take-off distance available on the runway to a distance of 15000m.
