    • Principles of Flight Chapter 4 - Stalling
    • Stalling
      • When the angle of attack is too great the airflow over the wing cannot meet the airflow under the wing.
    • 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
    • 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.
