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

INTRODUCTION

This chapter describes the pneumatic system of the Canadair Challenger (CL-600-2B16,
model CL-601-3A). The subsystems supplied from the pneumatic sources, as well as con-
trol indications and pneumatic leak detection, are also discussed.

GENERAL

The bleed-air system provides the air sources
for the pneumatic subsystems over which the
crew has direct or indirect control.
T h e p n e u m a t i c s y s t e m o f t h e C a n a d a i r
Challenger includes the bleed-air sources,
ducting, distribution, control, indication, and
duct-failure monitoring systems.
The pneumatic system has four sources of air:
(1) the left engine high-pressure compressor,

(2) the right engine high-pressure compressor,
(3) the auxiliary power unit, and (4) external air.
There are bleed ports on the 10th and 14th
stages of the CF34 engine. Two ports on each
engine are interconnected by a Y-duct on the
10th stage and a single port on the 14th stage.
A flow limiter limits air extraction to a spe-
cific percentage of the total airflow and thus
protects the engine in case of a manifold or
duct rupture. Check valves in each engine
bleed-air line prevent reverse flow from the
opposite engine.
