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

Types of Icing
Clear/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.
