Conversely an aircraft flying fast will need to use a low angle of attack otherwise it will generate too much lift and start to climb. Note: In steady wing's level flight, for every airspeed there is a corresponding angle of attack that will provide just the right amount of aerodynamic force to counteract gravity.

The cruise propeller usually has a little more pitch than the standard propeller fitted to the aircraft. A high speed propeller might be fitted when the aircraft is intended to be operating at, or above, rated power for short periods – in speed competition for example.

Lift on the aircraft can be controlled by controlling angle of attack (inclination of aircraft with respect to ground) & speed of aircraft. Lift depends upon suraface area of wing. ... On what working principle does an aeroplane work? ... What is the working principle of BP?
