maintain height with backpressure
– When stall occurs, apply full rudder in desired
direction and aft control column.
• During
– Count three rotations
• Recovery
– Apply full opposite rudder to stop rotation
– Ease control column forward to unstall the wings
– Level wings and ease out of dive
– As nose passes horizon, climb away.
Airmanship
• Lookout
• Pre-manoeuvre checks
• Do not use aileron to pick up wing drop
• Speed and manoeuvre limitations not to be
exceeded
• Smooth coordinated use of controls
• Correct handover/ takeover procedure
• UNINTENTIONAL STALL OR SPIN SHOULD
NEVER OCCUR!
