The Rotax 915 engine can provide maximum power of 141 hp for 5 minutes at a maximum engine
speed of 5.800 rpm and 135 hp continuously at a maximum engine speed of 5.500 rpm.
The relation between rpm and manifold pressure is described in Chapter 3.19.
3.4 ENGINE OVERSPEED
The engine maximum speed is
5.800 rpm.
In case of overspeed:
- From 5.800 up to 6.000 rpm:
find the cause of the problem and correct it
- Over 6.000 rpm:
inspect the engine in accordance with the manufacturer instructions
WARNING DANGER:
As the gyroplane is equipped with a ground adjustable pitch propeller. The standard
propeller pitch is set in the factory. The pitch angle of the propeller may not be altered
as the performance of the gyroplane may be severely reduced.
WARNING:
It is possible to exceed maximum rpm limits in level flight with throttle lever at 100%.
3.5 SPEED LIMITS
Never exceed speed (Vne): 85 kn
This speed must never be exceeded in order not to stress the gyroplane beyond its structural
limits.
This speed is indicated by a red mark on the air-speed indicator.
Normal operating speed (Vno): 75 kn
This is the highest speed which may be maintained in turbulence and in any flight configuration
without risk of damaging the gyroplane structure (green range in the air-speed indicator).
WARNING:
Above 75 kn, movements in pitch must be limited to avoid overstressing the airframe. At
speeds above 75 kn only small, gentle pitch control movements should be used.
