FUEL TANK SELECTORS
Two fuel tank selectors, one for each wing tank, are located on the overhead
panel. The selectors are labeled LEFT, ON and OFF and RIGHT ON and
OFF and provide mechanical position control of the two fuel tank shutoff
valves at the root of each wing tank. When placed in the ON position, both
shutoff valves in that tank are open, allowing fuel from that tank to ow freely
to the reservoir. When a fuel tank selector is placed in the OFF position,
the shutoff valves for that tank are closed, and prevent fuel from owing to
the reservoir. Normal fuel management is accomplished with both fuel tank
selectors in the ON position.
FUEL SELECTORS OFF WARNING SYSTEM
A fuel selectors off warning system is provided to alert the pilot if the fuel
selector valves for both the left and right wing tanks are placed in the OFF
position. If both selector valves are placed in the OFF position, a red LED
light installed directly above the left PFD will illuminate,
FUEL OFF L-R will
be displayed in the annunciation windows of the PFDs, and an aural warning
chime will sound through the aircraft speakers and headsets.
AUXILIARY FUEL PUMP
An auxiliary fuel pump switch, located on the lower left portion of the
instrument panel, is labeled AUX FUEL PUMP and has three positions: OFF,
STBY, and ON. When the switch is placed in the OFF position, the auxiliary
fuel pump is rendered inoperative. When the switch is placed in the STBY
position, the auxiliary fuel pump is armed and will automatically provide fuel
pressure when the fuel pressure in the fuel manifold assembly falls below
approximately 4 PSI. This switch position is used for normal engine
operations when the main ow of fuel is provided through the ejector boost
pump and the auxiliary fuel pump is used as a standby device. When the
auxiliary fuel pump switch is placed in the ON position, the auxiliary fuel pump
will operate continuously. This position is used for engine start. Place the
switch in the ON position any time when the auxiliary fuel pump cycles on and
off with the switch placed in the STBY position.
FUEL FLOW INDICATOR
A fuel ow indicator is installed within the Garmin G1000 Flight Displays and
provides an indication of engine fuel consumption in pounds per hour based
on Jet-A fuel. The indicator measures the ow of fuel downstream from the
fuel control unit prior to being routed to the ow divider.
NOTE: Detents are provided on the fuel selector valve “ON” and “OFF”
positions to give tactile conrmation of the selected valve position.
Movement of the selector valve handle beyond the detented positions is
possible with aggressive control movement, but is not recommended as
selector handle over-travel has no further effect on the valve position.
