Slow Flight, Stalls, and Spins

The maintenance of lift and control of an airplane in
flight requires a certain minimum airspeed. This
critical airspeed depends on certain factors, such as
gross weight, load factors, and existing density altitude.
The minimum speed below which further controlled
flight is impossible is called the stalling speed. An
important feature of pilot training is the development
of the ability to estimate the margin of safety above the
stalling speed. Also, the ability to determine the
characteristic responses of any airplane at different
airspeeds is of great importance to the pilot. The
student pilot, therefore, must develop this awareness in
order to safely avoid stalls and to operate an airplane
correctly and safely at slow airspeeds.
