In normal flight a light aeroplanederives its forward motion from the thrust provided by the engine-driven propeller.

Aerodynamicists have found it convenient to resolve that resultant force into just two components, that part acting backward along the flight path is the wing drag and that acting perpendicular to the flight path is the lift. The amount of lift, and drag, generated by the wings is chiefly dependent on:

The values in the expression are: • (the Greek letter rho) is the density of the air, in kg/m³ •v² is the flight speed in meters per second •A is the wing area in square meters •CL is a dimensionless quantity – the lift coefficient. Mostly depends on the ANGLE of attack and the SHAPE of the wing.
