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

INTRODUCTION

The Canadair Challenger CL-600-2B16, model CL-601-3R 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
17,900 pounds.
Fuel is supplied to the engines from two col-
lector tanks. Fuel is delivered from each col-
lector tank to its respective engine by a main
ejector pump located within the tank. Addi-
tional scavenge and transfer ejector pumps

are located within the main and auxiliary tanks
to ensure proper fuel distribution.
Electrically operated standby fuel pumps are
provided. 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 equalize by gravity flow or by open-
ing a LEFT to RIGHT or RIGHT to LEFT
powered crossfeed shutoff valve to transfer
from the main to auxiliary tank.
