BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual page 203

CAUTION
If idle speed stabilizes at approxi-
mately 57% N , the engine must be
2
shut down immediately and the con-
dition reported to maintenance.
Do not attempt to increase idle N
advancing the thrust lever because it
can result in serious damage to the
first-stage compressor blades.
Ground Start (External Air)
The procedures for engine starting using an ex-
ternal air supply are identical with those for
APU bleed-air starts. An approved external air
unit capable of 45 psi can be connected to the
adapter (Figure 7-15) located in an access on
the left side of the rear fuselage.
Figure 7-16 illustrates the use of bleed for
ground starting the first engine.
Ground Start (Cross Bleed Air)
The procedures for a ground start using a cross
bleed-air supply are similar to those for APU
bleed or external air source, except that the
APU bleed air (Figure 7-13) must be off.
Push the BLEED AIR switch (Figure 7-14)
of the operating engine and check that the
bleed-air pressure is 45 psi minimum, then
continue as for APU bleed-air start.
Figure 7-17 illustrates the availability of bleed
air during a cross bleed start of the left engine.

NOTE
Two conditions must be met before
moving the thrust lever to IDLE for
all engine starting:
1. Indicated ITT must be less than
120° C .
2. N rpm must be 20% minimum.
