A stall occurs when the smooth airflow over the
airplane's wing is disrupted, and the lift degenerates
rapidly. This is caused when the wing exceeds its
critical angle of attack. This can occur at any airspeed,
in any attitude, with any power setting. Critical angle of attack and stall.

The practice of stall recovery and the development of
awareness of stalls are of primary importance in pilot
training. The objectives in performing intentional stalls
are to familiarize the pilot with the conditions that
produce stalls, to assist in recognizing an approaching
stall, and to develop the habit of taking prompt
preventive or corrective action.

Intentional stalls should be performed at an altitude
that will provide adequate height above the ground for
recovery and return to normal level flight. Though it
depends on the degree to which a stall has progressed,
most stalls require some loss of altitude during
recovery. The longer it takes to recognize the
approaching stall, the more complete the stall is likely
to become, and the greater the loss of altitude to
be expected.
