EMERGENCY PROCEDURES
RSUK0287_POH_Cavalon Revision 2, Issue Date 24.06.2015 3-10
3.12.6 Low Fuel (if installed)
The LOW FUEL warning light is triggered as soon as 5 litres or less of useable fuel remain
in the tank. Perform a power-on landing at the nearest suitable location and be prepared for
engine failure after approximately 10 minutes remaining flight time.
3.12.7 Deleted.
3.12.8 Fan
When lit, this indicates that the engine mounted electrical blower fan is active. Monitor
engine instruments and be aware of higher electrical power consumption. If possible,
reduce engine power and increase speed.
3.13 Parameters out of Limits
PARAMETER EXCURSION CORRECTIVE ACTION
Engine Oil
Temperature
Upper
or
yellow arc
Reduce power and increase air speed. If condition
cannot be corrected, land as soon as practicable.
Lower
Allow engine to warm-up on ground.
Within lower
yellow arc
Uncritical as long as oil temperature has reached
normal operating range at or after take-off.
Cyl. Head
Temperature
Upper
Reduce power and increase air speed. If condition
cannot be corrected, land as soon as practicable.
Engine Oil
Pressure
Upper
or
yellow arc
Reduce power. If condition cannot be corrected, have
maintenance action performed prior to next flight.
Lower
If combined with other indications, such as rising oil
temperature or unusual engine behaviour, shut-down
engine and perform a power-off landing as per
Emergency Procedure “Engine failure”.
Otherwise, monitor engine instruments carefully and
land as soon as practicable. Have maintenance action
performed.
3.14 Rotor Bearing Temperature
Outside Air Temperature (OAT) and Rotor Bearing Temperature (RBT) indicators are
provided for condition monitoring of the rotor bearing. Both readings should be more or less
equal. If, in stabilized conditions, RBT rises suddenly above OAT, have bearing inspected. If
in flight and the temperature difference exceeds 50degC and rising, make a precautionary
landing and investigate.
