NORMAL PROCEDURES
ENGINE IGNITION PROCEDURES
For most operations, the ignition switch is left in the NORM position
(aft). With the switch in this position, ignition is on only when the starter
switch is in the START position.
NOTE
The use of ignition for extended periods of time will reduce
ignition system component life.
However, the ignition switch should be turned ON to provide continuous
ignition under the following conditions:
1.
Emergency engine starts without starter assist (refer to Section
3,
Airstarts).
2. Operation on water or slush covered runways.
3.
Flight in heavy precipitation.
4.
During inadvertent icing encounters until the inertial separator
has been in BYPASS for
5
minutes (refer to Section
3,
Icing).
5.
When near fuel exhaustion as indicated by RESERVOIR FUEL
LOW annunciator ON.
Refer to Section 7, Ignition System, for further details regarding the
ignition system.
ENGINE INERTIAL SEPARATOR PROCEDURES
An inertial separator system is built into the engine air inlet duct to
prevent ice buildups on the compressor inlet screen. The inertial
separator control should be moved to the BYPASS position prior to
running the engine during ground or flight operation in visible moisture
(clouds, rain, snow or ice crystals) with an OAT of 5°C (40°F) or less.
The BYPASS mode may also be used for ground operations or takeoffs
with dusty, sandy field conditions to minimize ingestion of foreign
.
.
particles into the compressor. Refer to the charts in Section
5
for
performance changes associated with the inertial separator in the

BYPASS mode.

,
The NORMAL mode is used for all other operating conditions, since it
provides a substantial inlet ram recovery. This results in more efficient

engine operation and higher critical altitude for a particular power

setting.
