Which of the following is correct in terms of fate of climb (R/C)?

A)
R/C = lift/drag
B)
R/C = excess power/weight
C)
R/C = excess lift/drag
D)
R/C = excess power/Thrust required

Correct Answer :   R/C = excess power/weight


Explanation : Rate of climb is nothing but the vertical velocity of the aircraft. Rate of climb can be defined as the ratio of excess power of the aircraft to the aircraft weight. Hence, Correct relation between rate of climb and power is as follows: R/C = excess power/weight. Where, R/C = rate of climb.
