NORMAL PROCEDURES
COLD WEATHER OPERATION
(Continued)
Use of an APU s recommended when ambient temperatures are below
O"F
(-18°C).
Assure that oil temperature is in tne areen arc
(10°C
to
-
99°C')
prior'to takeoff.
If snow or slusn covers the takeoff surface, allowance
must be made for
takeoff
d~stances which will be increasingly extended as the snow or
slush depth increases. The depth and
cokistency of this cover can, in
fact, prevent takeoff in many instances.
HIGH ALTITUDE OPERATION
At altitudes above
20,000
feet, a compressor surge may be
experienced if engine power is very rapidly re-applied immediately after
a power reduction. This characteristic is not detrimental to the engine
and can be eliminated completely by turning on cabin bleed heat to at
least the one-half setting.
ENGINE COMPRESSOR STALLS
An engine compressor stall may be noted by a single or multiple loud
"popping" noise from the engine compartment. This situation may be
resolved by reducing the engine power to a point where the "popping"
discontinues, and slowly advancing the throttle to the necessary setting
for continued flight. The use of cabin bleed heat may also help
eliminate engine compressor stalls if this situation is encountered.
