AMBER; LOW FUEL Right
The low fuel light is triggered with less than 6liter usable fuel in
the respective tank. This system is electrically independent of
the fuel QTY indication. In case of conflicting information
landing is advised as soon as practical.
•
GREEN; Fuel pump ON
The fuel pump ON light is triggered by the power supply to the
electric pump
– actual pump function of pressure built up must
be checked using the fuel pressure indication.
•
GREEN; Landing light ON
The landing light on is triggered by the landing light power
supply in both, WIG/WAG and ON mode.
•
GREEN; Pitot Heat ON
The pitot heat ON light is triggered by the power supply to the
heating element
– it does not sense actual current or
temperature built up. This must be checked in pre-flight
inspection.
•
BLUE; External Power ON
The external power ON light is triggered by the connected
external power. Never taxi with the External power light
illuminated.
Failure of the dimmer unit or its power supply results in inoperative
warning/caution and indication lights. Power supply can be restored with
the back-up battery.
