Take-off Run
Check engine has reached full power for take-off. Otherwise, abort take-off
Commencing the take-off run with high rotor rpm (280-320) and the stick fully back
means that there is a high starting drag load. The aircraft has to accelerate to approx.
50mph (depending on loading) to take off, and achieve the rotor rpm for the loading
conditions.
Therefore, to minimise the drag and enable maximum acceleration at high rotor rpm,
move the stick forwards to approximately the mid position as the aircraft starts to
move. Monitor rotor rpm carefully ensuring that it is increasing, if the stick is too far
forwards the rotor rpm will decay, and a serious accident can be caused!
When the nose comes up allow nose wheel to float at about 10 – 15 cm above the
runway by a balanced change of control stick position
Minimize lateral drift by applying appropriate lateral control stick input into cross wind
direction
Maintain directional control i.e. runway alignment with sensitive pedal input
Maintain attitude until speed increases and gyroplane lifts off (at about 80kmh
(50mph, 45KIAS), depending on loading and rotor)
Allow gyroplane to build-up speed in ground effect
CSP/VPP:
With a variable pitch propeller installed, refer to the
respective flight manual supplement in CHAPTER 9 for correct power
setting and handling procedure.
WARNING
Gyroplanes are fully controllable at very low speeds without exhibiting any
signs of wing stall or soft flight controls, as it would be perceived in a fixed
wing aircraft. However, operation ‘behind the power curve’ may have serious
consequences during take-off, initial climb or in any other situation within
close ground proximity. Always allow aircraft to build-up safe climb speed
before allowing it to gain height.
4.10 Climb
Perform initial climb at safe climb speed and adjust trim
Set power to maximum take-off power.
CAUTION
Full take off power will require right rudder input to counteract the high thrust
and torque load.
Check engine instruments and respect maximum take-off power time limit
Switch off second fuel pump at safe height
At safe altitude, the climb may be continued with VY and reduced power setting for
noise abatement
When desired altitude is approached, level gyroplane and reduce power
