2.3.2
Deicing
CAUTION
When ice, snow or slush is removed from the aircraft surface, care must be taken to
prevent entry and accumulation of ice, snow or slush into intakes or control surface
hinge areas.
Note
Deicing and anti-icing fluid may splash onto heated surfaces such as air data probes and
engine nacelles which can produce significant vapor.
Note
The forward area of the aircraft must be free of fluid residues prior to departure. Deicing
and anti-icing fluid can flow back onto the windshield during taxi or take-off.
Note
If fluid runs onto the windshield during application, it must be removed prior to taxi and
take-off. Deicing and anti-icing fluid can be removed by rinsing with approved cleaner and
a clean lint-free cloth.
Note
Under no circumstances should deicing and anti-icing fluid be applied directly to the:
−
Air data probes
−
Windshield and windows
−
Air intakes
−
Engine inlets
−
Brakes
−
Wheels.
Dry, powdery snow can be removed by sweeping with a brush or broom. Heavy, wet snow can
be removed by combination of:
−
Squeegees and brooms
−
Heated water
−
Solutions of heated water and deicing / anti-icing fluids.
Remove the contamination from the wings and stabilizers by sweeping in the aft and inboard
direction starting at the leading-edge tip.
Deicing / Anti-icing fluids can be used to quickly remove frost and assist in the melting and
removal of snow.
Deicing / Anti-icing fluids can be applied with a mop or brush from a bucket to melt ice to the
extent that it can be removed by manual means.
Portable spray equipment such as pressurized containers with spray wands and hand pumps
attached to a supply tank can be used to apply deicing / anti-icing fluids.
