EMERGENCY PROCEDURES
RSUK0287_POH_Cavalon Revision 2, Issue Date 24.06.2015 3-2
NOTE
The best engine-off glide ratio is about 1:3 at 90 km/h (55-60mph). Depending
on a possible headwind the glide may be extended by slightly increasing
airspeed. It is heavily recommended to train your forced landing capabilities
regularly, preferably with a qualified flight instructor.
3.2 Air Restart Procedure
Check fuel valve OPEN
Check fuel pump(s) ON
Check both magnetos ON
Throttle slightly open
With the left hand, turn the Main Switch/Starter key completely to OFF, then START
If possible, allow engine and oil to warm-up before full power is applied
NOTE
The starter interlock function prevents inadvertent starter engagement. Before
attempting an engine start, the interlock must be reset by turning the Main
Switch/Starter key to OFF.
3.3 Landing into Trees or High Vegetation
Assume the surface of the treetops or vegetation as level
Plan touch-down and flare with minimum ground speed and minimum rate of descent
As soon as the wheels contact the vegetation bring the rotor disc to level attitude to
avoid partial blade tip contact with vegetation
Shut down engine by switching magnetos OFF and master switch OFF
3.4 Degradation of Engine Power
A gradual decay in engine RPM, accompanied by a rough running engine or even vibration
may be an indicator for carburettor icing. In this case, continue with a high power setting
and change altitude into air which is less susceptible to carburettor icing.
If the situation cannot be corrected be prepared for further loss of power and ultimately
engine failure.
NOTE
The phenomenon of carburettor icing is extremely unlikely with this engine
type as the carburettor inlets draw warm air from within the engine
compartment. Note that this arrangement can work properly only when the
engine is at operating temperature.
