When the angle of attack of the wing becomes too great, the airflow over the wing can no longer meet the airflow under the wing, causing a stall. The stalling angle, usually around 15 degrees, is when lift is lost and the wing will stall. Various factors like weight, power, flaps, ice, damage, and maneuvers can impact an aircraft's stalling speed, with lower stalling speeds generally being better.

2. Stalling When the angle of attack is too great the airflow over the wing cannot meet the airflow under the wing.

3. Stalling Angle Once the air is unable to pass over the wing smoothly lift is lost. The stalling angle varies but it is usually about 15 ° The wing will always stall when it reaches the stalling angle

4. Stalling Speed Data can be found in the ‘Pilot’s Notes’ Book. Various Factors Effect Stalling Speed LOWER STALLING SPEED IS BETTER Weight – Extra Weight increases stalling speed Power – Higher the power, lower the stalling speed Flaps lowered reduce stalling speed Ice forms on the wing increasing stalling speed Damaged wings increase stalling speed Manoeuvres – steeper turns higher the stalling speed.
