Non-compliance can result in serious injuries or death!
Monitor operating limits. Limits must not be exceeded.
Good engine start behavior will be achieved when setting the
throttle at 50% (± 5%) during engine start. In the aircraft this
number approximately corresponds to a throttle lever travel of
1-2 cm.
NOTE
These numbers depend strongly on the design and the actua-
tion mechanism of the throttle leverage and will vary from air-
craft to aircraft.
Throttle must be reduced as required right after the engine start to
avoid unnecessary high engine rpm, while the engine is still cold.
