IV Starter button on control stick
The starter motor is operated in two different modes:
1) Starting the engine
The following prerequisites must be met in order the starter motor can be
used to start the engine:
power plant main switch switched on
power plant fully extended (note position indication on display)
ignition ON
engine speed 0 RPM
or:
The red emergency system switch flap is open.
In this case the starter motor can be operated in any position of the
power plant and independent of the engine speed (see page 7.3.47 ff)!
2) Pulse-Mode for propeller positioning
After the power plant has been switched off, the alignment of the propeller
in the retraction position can be supported by pressing the starter button.
The propeller is then slowly turned with the starter motor until just before the
retraction position.
For this special function of the starter motor, the following prerequisites
must be fulfilled:
power plant fully extended (note position indication on display)
ignition OFF
engine speed 0 RPM
emergency system inactive (red emergency system switch flap is closed)
propeller is not yet close to retraction position
