Description
Status Light for the Ignition (IGN)
This light is only used when the electronic ignition control unit is installed.
The status light for the ignition illuminates when the electronic ignition control is not
operating. In this case the conventional magneto ignition will be in use. The color is white.
The procedure to be followed upon illumination of the ignition status light is given in
4B.3 - FAILURES IN THE ELECTRICAL SYSTEM.
Starter Warning Light (START)
The starter warning light illuminates when the starter is being operated or when the
connection between the starter motor and the engine has not been broken. This occurs
when the pinion of the starter motor remains engaged with the propeller flywheel. The
color is red.
The procedure to be followed upon starter warning is given in 3.7.2 - FAILURES IN THE
ELECTRICAL SYSTEM.
Pitot Heating Caution Light (PITOT)
The Pitot heating caution light is illuminated when the Pitot heating is not switched on,
or when there is a failure of the Pitot heating system. The color is amber.
Prolonged operation of the Pitot heating on the ground can also cause the Pitot heating
caution light to illuminate. In this case it indicates the activation of the thermal switch, which
prevents overheating of the Pitot heating system on the ground. This is a normal function
of the system. After a cooling period, the heating system will be switched on again
automatically.
