Chapter 17: Performance

17.jpg

This chapter is about the production of thrust, power and performance of the aircraft in climb, cruise and descent. Airplane performance is a function of propulsive and aerodynamics forces. In equilibrium flight, lift is equal to airplane weight, thrust is equal to drag, and pitching moments about the center-of-gravity are balanced. The airplane accelerates when thrust is greater than drag. Airplane performance is based on net or excess thrust. Excess thrust is the difference between the total drag on the airplane, and thrust produced by the engines.

Pilots should be knowledgeable of the airplane and it’s operating limits to obtain maximum airplane performance.
