The FSCU shuts off the tail tank transfer pumps when the tail tank system is empty, or when the
auxiliary tank system is full.
An amber AUTO INHIB light on the FUEL control panel illuminates to indicate that rotor-burst
protection shroud pressure is low, and all automatic fuel transfer modes are disabled. This is
accompanied by the AUTO TAIL XFER INHIB caution EICAS message.
Normal operation of the automatic tail tank transfer pumps will not illuminate the switch/lights on
the FUEL control panel. If the primary or secondary tail transfer pump fails during automatic
operation, the FSCU switches to the other pump and displays the PRI (SEC) TAIL XFER FAIL
status EICAS message.

NOTE
Normal automatic fuel transfer between tail and auxiliary tanks is
inhibited while the aircraft is on the ground (weight-on-wheels
sensed by the proximity sensing electronic unit). On the ground,
transfer can only be accomplished by pressing the MANUAL OVRD
switch/light, and selecting the PRI or SEC transfer pump.
FSCU Manual Transfer Operation
The FSCU alerts the crew of tail tank fuel transfer abnormalities by EICAS messages. The
FUEL control panel allows the crew to override the FSCU automatic fuel transfer system.
The TAIL TANK HEAVY caution EICAS message alerts the crew of excessive tail tank fuel
weight (relative to the auxiliary tanks). By pressing the guarded MANUAL OVRD switch light, the
crew can manually transfer the tail tank fuel by selecting the guarded PRI (SEC) TAIL TANK
TRANSFER pump switch/light. The white ON indicator illuminates within the switch/light to
indicate satisfactory pump output pressure. If pump output pressure is low, or the pump has
failed, the amber FAIL indicator illuminates within the switch/light, and the PRI (SEC) TAIL XFER
PUMP caution EICAS message is displayed. If the transfer is unsuccessful, the crew can utilize
the tail tank fuel DUMP system to reduce the fuel quantity in the tail tank.
Similarly, the AUX TANK HEAVY caution EICAS message indicates excessive auxiliary tank fuel
weight (relative to the tail tank system). Selecting only the MANUAL OVRD switch/light will
override FSCU automatic transfer functions, stopping fuel transfer between the tail and auxiliary
tanks, thereby allowing the auxiliary tanks to deplete to normal levels.
NOTE
When operating in manual override, the selected (PRI or SEC) fuel
pump will not automatically shut off when the tail tank is empty. The
flight crew must monitor manual transfer operations, and turn off the
selected pump when the tail tank is empty

Fuel Dumping
If attempts to transfer fuel from the tail tank to the auxiliary tank fail, the tail tank fuel can be
dumped. Fuel dumping must be carried out with the flaps at 0°.
A guarded DUMP switch/light, powered by the DC battery bus, is located on the FUEL control
panel. Once pressed in, the dump valve is commanded open, and the white OPEN indicator
illuminates on the switch/light. Fuel is dumped at a rate of approximately 100–120 lb/min
(45–55 kg/min). Five minutes after the dump valve is selected OPEN, the DUMP VALVE OPEN
caution EICAS message is displayed, to remind the flight crew that the dump valve is open.
If the dump valve is not in the position commanded by the switch/light, the amber FAIL indicator
will illuminate, and the TAIL DUMP SOV caution EICAS message will be displayed.

NOTE
Fuel may be inadvertently dumped on the ground, via the fuel dump
mast, if the BATT MASTER switch is selected on, and the fuel
DUMP switch is pressed in.
Fuel Crossflow (XFLOW)
Whenever there is a fuel imbalance between the two main tanks (more than 400 lb on taxi,
takeoff or landing, or more than 800 lb in flight), the FUEL IMBALANCE caution EICAS message
