9-4 Fire Indication
9-4.1 General
Depending on customer’s configuration the gyroplane can be equipped with a Fire indicator
light to alert the pilot that a certain temperature in the engine compartment has been
exceeded (the engine is on fire). The fire indication circuit consists of a cable routed inside
the engine compartment. The cable has two integrated wires separated by an insulation
layer. At a defined temperature the insulation layer will melt and the embedded wires close
contact.
Engine fire (circuit short-closed, low resistance) will be indicated by a flashing/blinking Fire
indicator light in the Warning and Caution Panel. During normal operation (circuit closed,
‘normal’ resistance) the Fire indicator light will be off. A malfunction of the system (circuit
open) is indicated by a constantly lit Fire indication. At power-on the system will perform a
lamp test consisting of a series of three flashes.
OFF Normal Operation (normal resistance)
FLASHING Fire, abnormal temperature (circuit short-closed)
ON System Malfunction (circuit open)
