4.3.2. Extended Mode
The Extended mode is selected by
moving the Jet Control toggle switch to
the center position. If this mode is
selected while the Jet Engine is running,
the engine will be switched OFF and
cooled down.
The JDU will display the pylon in the extended state during this mode.
In the extended mode, the RUN screen can be displayed on the JDU
by pressing the Thrust Control Dial. This allows the pilot to familiarize
himself with the Jet screen in the run mode, without having to actually
start the Jet. This screen is also handy during the pre-flight inspection
of the system.
CAUTION:
During the Extended mode the electrical start motor will
automatically spool-up the compressor if the EGT is
above a threshold temperature set by the engine
manufacturer in order to cool the engine. Do not turn the
compressor by hand during this mode, as this may result
in injury or damage to the compressor.
