Tail Tank Amber Warning Lights Versus Master Caution; Fuel Jettison; Refueling And Defueling - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

Figure 5-13 shows the location of the con-
trols and lights. Figure 5-14 has the schematic
of the tail tank system.
TAIL TANK AMBER
WARNING LIGHTS VERSUS
MASTER CAUTION
A steady NOT ARMED light indicates that
there is fuel in the tail tank but the arming
switch has not been selected to ARMED. This
will not turn on the MASTER CAUTION.
A flashing NOT ARMED light indicates that
the arming switch is still in the OFF position
and the tail tank is ready to transfer fuel (no
MASTER CAUTION light yet).
After a short while, if the arming switch is still
not selected to the ARMED position, the Mas-
ter Caution system FUEL annunciator will il-
luminate and the MASTER CAUTION lights
will flash. This will occur whenever fuel is sup-
pose to be transferring from the tail tank and
it's not.
NOTE
NOT ARMED light will illumi-
nate if the Rotor Burst Detection
Switch in the pressurized shroud
senses less than 8.5 psi.

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.
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 is is not
possible to complete the jettison pro-
cedure, a landing may be made with
fuel in the tail cone tank.
WARNING
Do not jettison fuel in known light-
ning conditions.

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.
