NORMAL PROCEDURES
STARTING ENGINE (Continued)
CAUTION
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 idle (52%
Ng or above), return the starter
switch to the OFF position. With a cold
englne 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 52% Ng. To assure maintaining the minimum Ng and
1TT 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).
CAUTION
UNDER HOT OAT
AND/OR HIGH GROUND ELEVATION
CONDITIONS, IDLE ITT MAY EXCEED MAXIMUM IDLE
ITT LIMITATION OF 685°C. INCREASE Ng
AND/OR
REDUCE ACCESSORY LOAD TO MAINTAIN ITT WITHIN
LIMITS.
NOTE
If the STARTER ENERGIZED annunciator fails to go out
after the starter switch has been moved to the OFF
position, the start contactor may be closed and the
generator will not function. Perform an engine shutdown.
Engine starts may be made with airplane battery power or with an
auxiliary power unit (APU). However, it is recommended that an APU
be used when the ambient air temperature is less than 0°F (-18°C).
Refer to Cold Weather Operation in this section when ambient
temperature is below
0°F (-18°C).
