Fuel System and Fuel Transfer Operations
•
During normal operation fuel is taken from the main (left) tank only.
•
The auxiliary (right) tank cools warm fuel returned from the engine.
•
Fuel flows back to the main tank automatically, but an imbalance between
tanks may occur because of differential flow rates to/from the engine.
•
To keep tanks balanced (+/-‐ 20 liter difference), fuel must be transferred
manually from the auxiliary tank to the main tank by activating the
fuel
transfer pump
.
•
The transfer pump turns off automatically to avoid overfilling the main tank.
•
If the pump is not turned off, it will continue pumping each time the fuel
level in the main tank drops, but only as long as there is fuel in the auxiliary
tank.
•
The G1000 fuel transfer status indication is illuminated only while the pump
is running
.
•
The fuel system runs on mechanical engine-‐driven pumps.
•
The EMERGENCY TRANSFER value (near the throttle) activates an electric
pump that transfers fuel directly from the auxiliary tank to the engine.
•
CAUTION:
The EMERGENCY TRANSFER pump bypasses the main tank,
meaning that fuel starvation will occur if the EMERGENCY TRANSFER value is
set on and the auxiliary tank becomes empty, even if fuel remains in the main
tank.
