Question

Which of the following gives the best gradient of climb?

(a) Low airspeed which is closer to critical operating airspeed

(b) High airspeed which is closer to critical operating airspeed

(c) At any airspeed

(d) At high bypass ratio

I got this question by my school teacher while I was bunking the class.

My question comes from Climb Gradient in section Climb and Descent Performance of Aircraft Performance

Answer 1

Right choice is (a) Low airspeed which is closer to critical operating airspeed

To explain I would say: The best gradient of climb is achieved when the airspeed is low and closer to that of the critical operating speed. 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.
