After Landing Procedure
CAUTION: Taxi at a reduced speed. Use smaller nose wheel
steering wheel and rudder inputs and apply minimum
thrust smoothly. Differential thrust may be used to help
maintain airplane momentum during turns. At all
other times, apply thrust evenly. Taxiing on slippery
taxiways or runways at excessive speed or with high
crosswinds may start a skid.
CAUTION: When operating the engines over significant amounts of
standing de-icing or anti-icing fluid, limit thrust to the
minimum required. Excessive ingestion of de-icing or
anti-icing fluid can cause the fluid to build up on the
engine compressor blades resulting in compressor stalls
and engine surges.
Do the normal After Landing Procedure with the following
modifications:
After prolonged operation in icing conditions with the flaps extended,
or when an accumulation of airframe ice is observed, or when
operating on a runway or taxiway contaminated with ice, snow, slush
or standing water:
Do not retract the flaps to less than flaps 15 until the flap areas
have been checked to be free of contaminants.
Engine anti-ice must be selected ON and remain on during all ground
operations when icing conditions exist or are anticipated.
WARNING: Do not rely on airframe visual icing cues before
activating engine anti-ice. Use the temperature
and visible moisture criteria because late
activation of engine anti-ice may allow excessive
ingestion of ice and result in engine damage or
failure.
CAUTION: Do not use engine anti-ice when OAT is above
10°C.
When engine anti-ice is needed:
