STARTING ENGINE
The starting engine checklist procedures should be followed closely to
assure a satisfactory engine start. With the FUEL CONDITION lever in
the CUTOFF position, move the STARTER switch to the START
position; verify that the amber STARTER ON and white IGNITION ON
annunciators are shown. Next, check for a positive indication of engine
oil pressure. After N
g
stabilizes (minimum of 12%), move the FUEL
CONDITION lever to the LOW IDLE position and verify fuel flow in the
general range of 90 to 140 PPH. After the engine starts and during
acceleration to idle (approximately 55% N
g
), monitor ITT and N
g
.
Maximum ITT during engine start is 1090°C, limited to 2 seconds.
Typically, the ITT during start is well below this maximum value. After
the engine has stabilized at idle, the amber STARTER ON annunciator
should not be shown. If this annunciator remains ON, it indicates the
starter has not been automatically disengaged during the engine
starting sequence due to a failed speed sensor.
If no ITT rise is observed within 10 seconds after
moving the FUEL CONDITION lever to the LOW IDLE
position, or ITT rapidly approaches 1090°C, move the
FUEL CONDITION lever to CUTOFF and perform the
ENGINE CLEARING PROCEDURE in this section.
After the engine reaches stabilized idle (55% N
g
or above), return the
STARTER switch to the OFF position. With a cold engine or after
making a battery start (high initial generator load into battery), it may be
necessary to advance the POWER lever slightly ahead of the IDLE
detent to maintain a minimum idle of 55% N
g. To assure maintaining
the minimum Ng and ITT within limits, advance the POWER lever to
obtain approximately 55% Ng before turning the STARTER switch OFF
(the generator contactor closes when the STARTER switch is turned
OFF).
Under hot OAT and/or high ground elevation conditions,
idle ITT can exceed maximum idle ITT limitation of
700°C. Increase Ng and/or reduce accessory load to
maintain ITT within limits.
