D. Starting Engine(s) Using APU Air Supply (Cont’d)
(9) Engine instruments.............................................Monitor Check the following:
• Starter disengages at 55%
N2.
• IGNITION A (B) advisory
message goes out.
• ITT is 450 – 600°C (max.
during start is 900°C).
• N1 stabilizes and does not
drop below 22% RPM.
• Check that oil pressure is
within normal range [above
25 psi (174 kPa)].
(10) APU EGT indications............................................Check within normal limits.
(11) Idle speed.............................................................Check N2 variation between engines
is within 2%. If greater, notify
maintenance personnel.
E. Starting Engine Using External Air Supply
NOTE
AC power is required for this procedure.
(1) BLEED AIR, APU LCV switch/light..................Press out to close load control valve.
Check APU LCV OPEN light
out.
(2) External air ................................................... Connected Verify 45 psi minimum bleed
air pressure on status page.
NOTE
The external air source must be capable of supplying 45 psi manifold
pressure at the initiation of start, however, lower pressure units,
dependent upon altitude and flow, have been proven satisfactory.
(3) L (R) ENG START switch/light ..............................Press to start applicable engine.
Check the following:
• Applicable START light
comes on.
• IGNITION A (B), ON light
comes on.
• IGNITION A (B) advisory
message comes on.
• Check that there is positive
bleed air pressure.

1. POWER PLANT (CONT'D)
E. Starting Engine Using External Air Supply (Cont’d)
When N2 reaches 20% RPM and ITT is below 120°C:
(4) Left or right thrust lever ....................................Advance applicable lever to IDLE.
NOTE
If ITT is greater than 120°C prior to start, engine must be dry motored
to lower ITT to 120°C before moving thrust lever to IDLE. The starter
cranking limit of 90 seconds for first attempt must be adhered to.
(5) Engine instruments.............................................Monitor Check the following:
• Starter disengages at 55%
N2.
• IGNITION A (B) advisory
message goes out.
• ITT is 450 – 600°C (max.
during start is 900°C).
• N1 stabilizes and does not
drop below 22% RPM.
• Check that oil pressure is
within normal range [above
25 psi (174 kPa)].
F. Starting Engine Using Engine Cross Bleed Air
CAUTION
This procedure requires the use of higher than normal thrust settings
on the ground. Ensure that intake and exhaust areas of the operating
engine are secure.
When starting engines in close quarters, consideration should be given
to the effects of jet blast.
(1) BLEED AIR, APU LCV switch/light..................Press out to close load control valve.
Check APU LCV OPEN light
out.
(2) BLEED AIR, 10TH STAGE L (R)
switch/light .........................................................Press in to open 10th stage SOV for
operating engine.
Check L (R) 10TH STAGE
CLOSED light out.
(3) Status page ..........................................................Select and monitor bleed pressure.
(4) Thrust lever of operating engine.......................Advance to achieve a minimum of
60 psi bleed air pressure
(approximately 85% N2).
