Question

The system of forces acting on the aircraft are propulsive forces, aerodynamic forces, gravitational forces and these result in inertial forces.

(a) True

(b) False

This question was posed to me at a job interview.

I'm obligated to ask this question of Equations of Motion for Performance topic in portion Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

Right answer is (a) True

To explain I would say: The system of forces acting on the aircraft are propulsive forces, aerodynamic forces, gravitational forces and these result in inertial forces. From Newton’s law the equation becomes Fa+Fp+Fg=Ft where Fa=aerodynamic forces, Fp=propulsive forces, Fg=gravitational forces and Fl=inertial forces.
