A chip detection system enables the monitoring of the engine oil system. The
system includes one chip
detector installed on the propeller reduction gearbox and
a second chip detector installed on the engine accessory gearbox. In case of chip
detection,
CHIP is displayed in the CAS window.
Lubrication system content, cooler
included, is 12.7 quarts (12 liters). A graduated
dipstick allows checking oil quantity in the system. A visual oil sight glass, located
on the left side of the engine, allows a rapid checking of the oil level.
NOTE
For checking and oil filling-up, refer to
Paragraph Engine Oil in Subsection
8.7. .
Engine Operations
See Figure 7.6.8.
FADEC Power-up
During initialization, the FADEC performs built-in tests:
- to
confirm the functioning of each channel's computing hardware, safety-
related features, and key interfaces,
- to identity any fault.
During this time, the FADEC briefly activates the output effectors on both
channels. As a result it is normal for the pilot and the avionics to observe the effect
of the activated output effectors (e.g spurious messages, etc.).
Ignition Function
The ignition system consists of an ignition unit that supplies, from 28 V source,
high voltage current necessary to two spark igniter plugs.
The IGNITION pushbutton, located on the ENGINE/FUEL panel of the upper
panel, enables the pilot to select between AUTO or ON positions:
- In the AUTO position, the FADEC controls the ignition system:
. during engine start,
. under certain conditions, to avoid engine flameout.
- In the ON position, the pilot commands continuous ignition.
IGNITION is displayed in the CAS window as long as the spark igniter plugs are
supplied.
The table hereafter gives
the status light colors corresponding to the state of the
system.
