Stability Aerodynamics

MANOEUVRING FLIGHT Although no airplane is completely stable, all airplanes must have desirable stability and handling characteristics. An inherently stable airplane is easy to fly, and it reduces pilot fatigue. This quality is essential throughout a wide range of flight conditions – during climbs, descents, turns, and at both high and low airspeeds. You will…

Aerodynamics of Manouevring Flight

Three Axes of Flight All manoeuvring flight takes place around one or more of the three axes of rotation. They are called the longitudinal, lateral and vertical axes of flight. The common reference point for the three axes is the airplane’s centre of gravity (CG), which is the theoretical point where the entire weight of…

PRINCIPLES OF FLIGHT

THE FOUR FORCES OF FLIGHT During flight, the four forces acting on the airplane are lift, weight, thrust, and drag. Lift is the upward force created by the effect of airflow as it passes over and under the wings. It supports the airplane in flight. Weight opposes lift. It is caused by the downward pull…
