# Drag power of an aircraft is achieved by multiplying drag force

Drag power of an aircraft is achieved by multiplying drag force with true airspeed.

A. True

B. False

The question was posed to me in an interview for internship.

I need to ask this question from Minimum Power Speed topic in division Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Correct option is A. True

Easy explanation: Drag power of an aircraft is achieved by multiplying drag force with true airspeed. The formula for drap power is given as P$$\sqrt{\sigma}$$=DVe=YVe^3+$$\frac{ZW^2}{V_e}$$ where Y is a constant, Ve is velocity, W is weight, Z is constant and D is total drag and P is power.
