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

INTRODUCTION

This chapter deals with the auxiliary power unit (APU) installed as standard equipment
on the Canadair Challenger CL-600-2B16, model CL-601-3A/R. The APU renders the
airplane completely independent of such ground servicing requirements as electrical power,
pneumatic power for engine starting, and an air supply for the environmental systems.

GENERAL

The APU is a small, lightweight, gas-turbine
engine, certificated for ground and in-flight op-
eration. The unit is manufactured by Garrett
Turbine Engine Company and designated
"GTCP-36-100(E)."
The APU is equipped with self-contained oil,
fuel, and ignition systems. During starting
and operation, the APU is monitored by an
electronic control unit (ECU). If any primary

parameters are exceeded, the ECU will auto-
matically shut down the APU.
Separate fire protection, consisting of a mon-
itored fire detection system and a fire extin-
guishing system, is provided for the APU.
The APU's only dependencies are (1) an elec-
trical power source for starting from either
the airplane battery or from an external DC
power unit and (2) a fuel supply from the air-
plane's main fuel system.
