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

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)
