NOTE
Normally the cooling down of the engine during descent and taxi will be
sufficient to allow the engine to be shut off as soon as the aircraft is stopped.
At increased operating temperatures make an engine cooling run of at least 2
minutes.
Always comply with the cool-down recommendations in the ROTAX engine
operators manual.
NOTE
Due to the pusher engine arrangement, a ground engine cool-down is
inefficient and may be counter-productive. If necessary park into wind so that
air is driven naturally into the engine bay air intakes.
4.18 Parking
Install rotor tie-down bag
Secure gyroplane against rolling using parking brake and chocks, if parked on a
slope
Double check to have master switched OFF and keys removed
Install protection cover if available or appropriate
NOTE
Avoid long term parking of the aircraft with empty tanks. This will increase the
risk of water accumulation in the tanks and will lead to shrinking of the rubber
tank seals.
4.19 Special Procedure: Short Field Take-off
A short field take-off with high pre-rotation speed puts high loads on pre-rotator and rotor
and requires a modified procedure. As a consequence, short field take-offs with high pre-
rotation shall only be performed after adequate training and only when necessary.
Perform normal take-off procedure until clutch is fully engaged
Carefully increase engine power to maximum, which will give up to 320 R-RPM
depending the aircraft loading and friction with the ground (at light loading the aircraft
may slide forwards with the wheel brakes locked).
In case of a slipping clutch (CLUTCH light), reduce power to match engine to rotor
speed
With the stick moved slightly aft (which will disengage the pre-rotator), release the
wheel brake without reducing engine power
As the aircraft accelerates, move the stick further aft to allow the rotor RPM to
increase. Do not let the rpm decrease!
Allow gyroplane to lift off and gain speed
