Fuel Jettison; Refueling And Defueling - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

The fuel transfer line has a nitrogen-pres-
surized shroud in the rotor boost zone. A
perforation in this shroud signals all open
shutoff valves to close and shuts down the
boost pump. Fuel transfer cannot be accom-
plished unless the shroud is replaced and
pressurized. Fuel in this case has to be jetti-
soned.
See Figure 5-18 for a schematic of the tail
tank system.

FUEL JETTISON

Pressing the DUMP SW ARMED switchlight
causes it to illuminate green, the white DUMP
SELECT light illuminates and arms the DUMP
SELECT/DUMP OPEN guarded switchlight.
Once armed, pressing the green DUMP OPEN
switchlight causes it to illuminate and opens
the jettison valve. Fuel discharges at a rate of
100 pounds per minute.
NOTE
Fuel jettison must only be carried
out with flaps set at 0°. If an imme-
diate landing is required, the fuel
jettison procedure should be initi-
ated immediately. However, if it is
not possible to complete the jetti-
son procedure, a landing may be
made with fuel in the tail cone tank.

REFUELING AND DEFUELING

Refueling can only be accomplished if the
auxiliary tank is full. The refuel-defuel panel
is equipped with a tail tank refuel-defuel
switch. When placed to FUEL, the green CL
light remains on until the auxiliary is full, and
then the amber OP light comes on, indicating
the refueling is taking place.
Defueling can be carried out any time, regard-
less of fuel quantity. There is no provision for
gravity refueling.
