Stalling Pre Flight Objective • To be able to recognise the usual symptoms leading up to a stall • Recognise the symptoms of the stall itself • To be able to recover with a minimum hight loss under varying configurations • Aim for no more than a 100 foot loss of height Application • High Angle of attack / Low IAS • Take-off and landing • Sharp pull-up or steep turn Review • Stall • Manoeuvres • Flap • Power • Ailerons Revision Usual Symptoms Close to the stall 1. High nose attitude 2. Low IAS 3. Reduced effectiveness of controls 4. Stall Warning 5. Control Buffet Symptoms of a stall 1. Loss of height 2. Nose pitch down Airmanship • Inadvertent stalls should never occur • Lookout • Smooth co-ordinated control input • Correct handover/takeover procedure • Monitor engine gauges Air Exercise • Pre Entry – Lookout – Pick reference point – Manoeuvre checks: – H – H – E – L – L – L eight sufficient to recover by 3000ft AGL! atches/Harnesses secure ngine Temperature & Pressures ocation – not above a populated area oose articles secure ookout (360 degree turn) Air Exercise • Entry – Pick a reference point – Retard throttle, maintaining height (Keep straight with rudder) – Note the symptoms • Stall • Recovery – (Release back pressure) Lower nose to descending attitude – Allow speed to increase through 65KIAS, full power – Ease into the climb • Wing drop recovery – Keep aileron neutral – Apply full opposite rudder to stop yaw and or bank – (Release back pressure) Lower nose to unstall – Once unstalled, Centralise the rudder, full power (Keep straight with rudder) – Ease into the climb Air Exercise • Various Stall Configurations – Clean stall – Clean stall with power – Stall with flap – Stall with flap and power I’ll see you in HHELLL
