Flight position:
Hold the stick
fully forward
and
centred
with your
right hand. With your left hand, move to “Flight” position the selector.
Wait five seconds for the pneumatic system to fully charge.
5.
Pre-rotation:
Push and hold the pre-rotator button on the control stick
with your thumb. This causes the pre-rotator to engage. You will hear
the pre-rotator belt making some squeak, wait until the pre-rotator belt
doesn´t make noise, then increase the engine power slowly and
gradually until reaching 220 rotor rpm.
For shorter take-off it is advisable to increase the rotor rpm up to
300 but the stress of the system will be higher so don´t do it if
it’s not necessary.
CAUTION
Start the take-off with the rotor between 150 - 200 rpm requires a
high skill. It is forbidden to proceed with take-off operations if the
rotor is under 150 rpm.
WARNING
Before engaging the pre-rotator, check that the area is clear and
consider the risk that passenger’s hair or loose garment can be
caught by the pre-rotator drive shaft.
WARNING
Do not engage the pre-rotator with the wheels parking brake ON.
Hold the brake lever with your left hand. It is extremely dangerous to
start the take-off run if the parking brake is not disengaged!
