What A Stall Is
At a specific critical angle of attack, smooth airflow over the wing is no
longer possible. A wing stall results when this critical angle of attack is
exceeded. Accidental stalls normally occur as a result of flying too slow on
takeoff or approach to landing. However, it is possible to exceed the
critical angle of attack and stall an airplane at any airspeed or airplane
Once the wing exceeds the critical angle of attack, the amount of lift produced
by the wing drops sharply. The angle of attack must be reduced to recover
from the stall.
What A Stall Is Not
Many students think of the engine stalling. This is an understandable
assumption, but wing stalls are not connected with engine failures. A
stall can occur at any power setting.
Why Stall Training Is Necessary
Stall training teaches the student what the airplane feels like when it is
approaching a stall, as well as what happens when the airplane stalls. By
practicing and becoming proficient at stalls, the student will be able to read
the warning signs of an impending stall and take appropriate action to avoid
stalling the airplane. If the airplane should be accidentally made to
stall, the pilot will be able to take appropriate action to recover from that
Since accidental stalls typically occur just after takeoff or when approaching
the airport for landing, stall training is focused on these two scenarios.
During flight training, you will become proficient at recovery just prior to a
stall. You will learn how to recover from a stall during approach for
landing, known as a power off stall. You will also learn to recover from a
departure stall, also called a power on stall.
