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

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

STALLING & SLOW FLIGHT
OBJECTIVE:
To be able to recognise the symptoms of an impending stall, the stall itself, and to
recover with a minimum height loss of 100ft under varying conditions of power
and flap.
APPLICATION:
Slow speed flight such as approach and landing.
AIRMANSHIP:
 Smooth coordinated use of controls
 Correct hand over/Take over technique: - Instructor: “Handing over”
Student: “I have control”
or
Instructor: “Taking over”
Student: “Handing over”
Instructor: “I have control”
 Lookout (use the clock rule; ie. aircraft sighted 12 o’ clock high)
 Reference to natural horizon
 Unintentional stall should never occur
 Pre-stalling checks
AIR EXERCISE:
 Pre-stalling checks
 Height sufficient to recover by 3000ft
 Hatches and harnesses secure
 Engine FMOST checks
 Lookout
 Location
 Loose articles secure
 Reference point
Entry
 Throttle to idle
 As IAS decreases increase back pressure to maintain altitude
Stalling & Slow Flight
During
 Symptoms – high nose attitude, low IAS, sloppy controls, stall warning, buffet
 Stall – height loss and nose pitches down. Possible wing drop
Recovery
 Relax back pressure and put nose 5 fingers below horizon
 Correct wing drop if needed by using opposite rudder (DO NOT use ailerons)
 As speed increases apply full power
 Adopt climb attitude
Stalling & Slow Flight
Sequence 13
Effects of power on stall symptoms
 1500RPM
 Speed reduces more quickly
 Shorter stall warning
 Stall speed is lower
 Wing drop more likely
Effects of power on recovery
 At stall, adopt attitude 5 fingers below horizon
 Correct for any wing drop with opposite rudder
 Apply full power
 Raise nose to Straight and level attitude (3 fingers below horizon)
