De-icing / Anti-icing
Testing of undiluted de-icing/anti-icing fluids has shown that some of the
fluid remains on the wing during takeoff rotation and initial climb. The
residual fluid causes a temporary decrease in lift and increase in drag,
however, the effects are temporary. Use the normal takeoff rotation rate.
CAUTION: Operate the APU during de-icing only if necessary.
Ingestion of snow, slush, ice, or de-icing/anti-icing fluid
can cause damage to the APU.
If de-icing / anti-icing is needed:
APU ....................................................................... As needed F/O
The APU should be shut down unless APU operation is necessary.
Call “FLAPS UP” C
Flaps ..................................................................................UP F/O
Prevents ice and slush from accumulating in flap cavities during
de-icing.
Thrust levers .....................................................................Idle C
Reduces the possibility of injury to personnel at inlet or exhaust
areas.
PACK switches ..................................................................................OFF
After de-icing / anti-icing is completed:
APU ................................................................. As needed F/O
PACK switches ........................................................................ AUTO
