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.
