4.10 Advanced Procedures
The following procedures are advanced techniques designed for special circumstances. To carry
them out successfully the pilot must be well trained and experienced in the particular aircraft being
used. Before attempting them the pilot must realistically assess the circumstances and their skills.
WARNING
The following procedures are used in less than optimal conditions. They are inherently less safe
than normal procedures. The operator attempts them at their own risk.
4.10.1
Short Field Take-Off
Crew .......................................................HARNESS SECURE / BRACE
Aircraft Weight .........................................MINIMISE
Ground Inspection ...................................COMPLETE
Measure runway length ............................MARK TAKE-OFF ABORT POINT
Wheel Spats .............................................ON FOR LONG GRASS
OFF FOR SOFT SURFACE
Elevator Trim ............................................NEUTRAL
Fuel Shutoff valve ....................................ON
Fuel Pump ................................................ON
Carburettor Heat ......................................OFF (COLD)
Wing Flaps ...............................................TAKE OFF (1
st
Stage)
Position ....................................................FOR MAX POSSIBLE RUNWAY LENGTH
Engine ......................................................WARM THOROUGHLY
Brakes ......................................................HOLD FULL ON BY HAND
Throttle .....................................................FULL. Wait for engine RPM to peak
Brakes ......................................................RELEASE
Elevator ....................................................FULL BACK until nose wheel lifts 25mm
(1”).
AS REQUIRED after
Abort ........................................................IF NOT AIRBORNE BY ABORT POINT
Rotate ......................................................AS SOON AS POSSIBLE
Lift-off .......................................................BEST ANGLE OF CLIMB SPEED until clear
of obstacles.
NOTE
Short field take-offs are potentially high risk manoeuvres. Reducing rotation and climb speeds
lower
the aircraft’s safety margins, especially in a cross wind, wind gust or if the engine fails.
Where possible, they should only be attempted in good conditions. If students are being taught
short field take-offs the weather conditions must be appropriate and a long runway used.
WARNING
If high power is applied when the propeller is over loose gravel, grass etc propeller damage will
result.
WARNING
It is possible to over-rotate the aircraft in ground effect to a dangerously nose-high pitch, resulting
in a stall once clear of ground effect. Allow pitch angle & airspeed to stabilise out of ground effect
before applying aggressive pitch inputs.
