Fuel System; Introduction; General - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

INTRODUCTION

The Canadair Challenger CL-600-2B16, model CL-601-3A fuel system provides fuel
for the two turbofan engines, as well as the auxiliary power unit (APU). Fuel is also used
to cool the APU generator adapter oil and the main engine oil.

GENERAL

The Challenger uses a wet-wing box struc-
ture which forms three separate fuel tanks;
two main tanks in the outboard wing sections
and an auxiliary tank in the wing center sec-
tion. Maximum fuel capacity is approximately
16,500 pounds.
NOTE
Aircraft incorporating SB-601-0262,
maximum fuel capacity is approxi-
mately 17,900 pounds, due to the
addition of a tail tank.
Fuel is supplied to the engines from two collector
tanks. Fuel is delivered from each collector tank

to its respective engine by a main ejector pump
located within the tank. Additional scavenge and
transfer ejector pumps are located within the
main and auxiliary tanks to ensure proper fuel
distribution.
Electrically operated standby fuel pumps are pro-
vided. These pumps are operated during engine
starting or following a main ejector pump failure.
A fuel imbalance between the main tanks may
be corrected by opening a crossflow valve. This
allows the quantities in the main tanks to equal-
ize by gravity flow. For airplanes fitted with
SB-601-0225, opening a LEFT to RIGHT or a
RIGHT to LEFT powered crossfeed shutoff
valve will transfer fuel from the one main tank
to the other.
