OTHER EFFECTS
Block the pitot and static inlets leading
Skin damage from chunks of ice breaking off
propellers
Obscuration of windscreens
Control surface jam
Radio interference due to ice build-up on aerials
Landing gear deployment / retraction problems
5. Intensity of Icing
TRACE - PERCEPTIBLE, NO SIGNIFICANT
ACCUMULATION
LIGHT - SIGNIFICANT ACCUMULATION FOR A
PROLONGED FLIGHT (OVER 1 HOUR)
MODERATE - SIGNIFICANT ACCUMULATION FOR
SHORTER PERIODS OF FLIGHT
SEVERE - RAPID, DANGEROUS ACCUMULATIONS

Types of Icing
Clear ice, or glaze ice, forms when large
supercooled droplets impact with an airframe.
Forms from impact with small supercooled
droplets.
Combination of clear ice and rime ice and
occurs where both types of water droplets are
present.
This type of icing is very severe and very similar
to clear ice.
