Hydraulic Power Systems - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

INTRODUCTION
The Canadair Challenger CL-600-2B16, model CL-601-3A/R has three independent
hydraulic systems, designated systems "No. 1," "No. 2," and "No. 3." Employing both
engine-driven and electrically driven pumps, the systems provide pressure for actuation
of primary flight controls, flight and ground spoilers, landing gear, nosewheel steering,
and brakes.
GENERAL
All three systems are completely independent
with no fluid connection or interchange. Each
system has a primary pump and a backup pump.
The primary pumps for systems No. 1 and No.
2 are engine driven. System No. 3 has an AC
electrical pump as the primary pump, which is
pilot-controlled by a switch. This pump is des-
ignated as hydraulic pump 3A. There is no pilot
control of the engine-driven pumps except for
a motor-driven shutoff valve activated by the
ENG FIRE PUSH switchlight.

CHAPTER 13
The backup pumps are all AC electrical pumps
and are pilot-controlled by switches. These
pumps are designated as the hydraulic B pumps.
The hydraulic B pumps are operated in the
event of a primary pump failure and for take-
off and landing. In addition, the hydraulic B
pump for system No. 3 automatically operates
when the air-driven generator (ADG) deploys.
All pumps are of variable volume and supply
3,000 psi when operating.
