Ex 10b. Stalling
Aim:
To recognise and enter a fully-developed stall from various modes of flight both straight and turning, and then to recover with minimum height-loss to a safe flight mode. Also to recover to a safe flight mode at the incipient stall stage.
Airmanship:
- Special attention to lookout – clearing turn to check rear
- Checks to ensure safe operation through exercise i.e.: height/location etc
Principles and characteristics at the stall:
- Effectiveness of controls
- Inherent stability of aircraft at stall e.g. Washout
- Buffet and other indications e.g. Severe rearward bar pressure on weightshift aircraft
- Wing dropping tendencies and correct handling of controls i.e. dangers of using roll control to level wings at the point of stall.
Factors affecting the stalling speed:
- Flaps (if applicable)
- Power
- Weight
- Load factor i.e. centrifugal force in steep turns
Full Stall and recovery; (from straight flight – level, climbing and descending)
- Use of controls
- Use of power (Recovery with and without the use of power)
Full Stall and recovery; (from turning flight – 30° angle of bank – level, climbing and descending)
- Use of controls
- Use of power (recovery with and without the use of power)
Stall and recovery at the incipient stage:
- Recovery during various attitudes and configurations
- Recovery during changing configurations
Stalling at higher speed:
- Secondary stall
- ‘g’ stall
