(7) 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)].
(8) Thrust lever of first engine....................................Select to IDLE.
(9) Idle speed.............................................................Check N2 variation between engines
is within 2%. If greater, notify
maintenance personnel.

G. Failure to Start
Light-Off:
Light-off, as indicated by a rise in ITT, is normally achieved within 10 seconds from thrust
lever operation. Starter motor operation continues until automatic disengagement occurs at
55% N2 (normally within 20 – 40 seconds), or if the start is aborted by selecting STOP.
Failure to Start:
(1) Thrust lever of starting engine..............................Select to SHUT OFF.
(2) IGNITION ........................................................... Disarm
(3) Dry motor until ITT is below 120°C
(maximum 90 seconds) ............................... Accomplish
At ambient temperatures of greater than 15°C (59°F), the start must be aborted if the engine
fails to start (no light-off) after 25 seconds from thrust lever movement to IDLE.
After 60 seconds of start operation and the engine has not reached starter cutout speed, the
start should be aborted by selecting STOP. Move the thrust lever to SHUT OFF. Motor engine
with ignition off and thrust lever at SHUT OFF within starter limits (Refer to Chapter 2;
LIMITATIONS – POWER PLANT).
At temperatures below 15°C (59°F), the start sequence may exceed 60 seconds.
H. After Starting Engines
CAUTION
If N2 is 57% or below and OAT is above −20°C (−4°F), do not
accelerate above idle.
NOTE
1. Do not accelerate engine until oil pressure has stabilized below 116
psi.
2. A high vortex noise may occur during stationary engine run-up to
high power in crosswind or tailwind conditions. This phenomenon is
not harmful to the engines and may be ignored.

(2) ANTI-ICE, WING switch .............................. As required
(3) ANTI-ICE, COWL L and R
switch/lights ................................................. As required

switch/lights .....................................................Press out to select cowl anti-ice off.
Check the following:
• COWL A/ICE ON advisory
message out.
• ITT gauges indicate drop in
