EMERGENCY PROCEDURES
RSUK0287_POH_Cavalon Revision 2, Issue Date 24.06.2015 3-9
Battery voltage of the system has dropped below a safe value. Refer to chapter above.
Aircraft lights and the 12V power receptacle will be disabled automatically.
3.12.3 BOOST WARN Light ‘Boost’ (red) - only ROTAX 914 UL
Continuously lit
If continuously lit, the maximum admissible boost pressure was exceeded. Reduce power
into normal operating range and consider restricted engine performance or boost control
malfunction. Record duration and have maintenance action performed.
Blinking
When blinking, the allowable 5 minutes take-off power time limit has been exceeded.
Reduce power into continuous range. Record duration and have maintenance action
performed.
3.12.4 BOOST CAUTION Light ‘Caution’ (orange) - only ROTAX 914 UL
A blinking BOOST CAUTION light indicates a problem with the turbo/boost control, its
sensors or the servo. Engine power is degraded and continuous operation may lead to
engine damage. Perform a precautionary landing considering reduced engine performance
and be prepared for engine failure.
3.12.5 Fire
Refer to emergency procedure “Smoke and Fire” and Flight Manual Supplement.
The Fire Warning system works by constantly checking the resistance of a special cable
mounted in both the engine bay and in the battery and fuel pump bay. This cable contains
two wires where the insulation between the two wires melts beyond 180degC, creating a
short circuit. The cable has a resistor at the end of the cable to give a known standard
resistance of the detection loop.
This lamp will flash three times when the keyswitch is turned on. This indicates the system
has made a satisfactory self test. The lamp will then normally remain off.
The lamp will light a solid red when a fault has been detected (eg a short circuit to ground or
open circuit).
A repair is required.
The light will flash brightly if a closed circuit is detected. This indicates that the cable
temperature has exceeded 180degC, and therefore that a fire may be present. Action as
‘3.6, Smoke and Fire’
