3.9.7
Pitot
The PITOT lamp is coloured green to indicate at night that the power is turned on to the
pitot tube heating. Red indicates heating failure.
3.9.8
Fan
The thermo switch of the engine mounted electrical blower has closed, fan is activated.
Monitor engine instruments and mind higher electrical power consumption. If possible,
reduce engine power and increase speed.
3.9.9
Water Temperature Indication
The water temperature indication illustrates three colour-coded temperature ranges of the
engine cooling water:
INDICATION
TEMP.RANGE
CORRECTIVE ACTION
Red light
Above 120 °C
Further reduce power. If condition cannot be
corrected, land as soon as practicable.
Yellow light
105 – 120 °C
Reduce power and increase air speed.
Green light
Below 105 °C
Normal operation
3.9.10 Water level
The water level indicates amber when the level is below minimum.

Uncritical because this is the temperature of the oil on
return to the engine having passed through the oil
cooler. It is known through the flight test program that
the oil is far hotter as it leaves the engine.
NOTE that the oil temperature sensor is mounted in the
engine, not in the oil tank (Cavalon recreational has the
sensor in the oil tank)
