6.8.1 Version with engine Emergency Switch

After activating Emergency Mode the yellow in-
dicator (1) turns on.
During emergency operation the exhaust gas
temperature (EGT) must be monitored.
Adjust the power lever such that the exhaust
gas temperature is in a range between 600 and
750 °C, depending on rpm. If the exhaust gas
temperature exceeds the limit, the power must
be reduced until the temperature comes be-
tween limits again. At low power settings the
exhaust gas temperatures may be lower than
stated. In such cases the power lever should be
adjusted such that the engine runs as smooth
as possible.
Note:
The engine may be restarted in emergency mode as long as the main battery is functional and the
master switch is in the "ON" position.
If the red warning light (1) on the status indicator
"Discharge" comes on, consider the following:
•
The electrical system is disturbed.
•
The operating time for the engine is limited.
(Check the flight manual for the time re-
maining to fly).
•
Take course to the next possible landing
site. Adjust your flight attitude to a maxi-
mum range (climb at elevated speed),
check the flight manual.
•
The engine may not be restarted with the
electric starter (Starting only possible by
windmilling and considerable loss of alti-
tude).
Caution:
If the lamp "Emergency Battery Discharge" comes on, the time availa-ble to operate
the engine is limited.
