Question

The true air speed have to be converted into calibrated airspeed before multiplication to derive the drag power equation.

(a) True

(b) False

I got this question in a national level competition.

Question is taken from Minimum Power Speed topic in division Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

Correct choice is (b) False

For explanation: The true air speed have to be converted into equivalent airspeed before multiplication to derive the drag power equation. The equation of the drag power equation is P\(\sqrt{\sigma}\)=YVe^3+\(\frac{ZW^2}{V_e}\) where Y is a constant, W is weight, Ve is velocity, Z is constant and D is total drag and P is power.
