In-flight icing is the accretion of supercooled liquid water
(SLW) on the airframe. This SLW can be in the form of cloud
droplets or freezing rain/drizzle. Generally, cloud ice and snow do
not adhere to the airframe, and graupel and small hail may actually
help to remove accreted ice...
Aero-Linx: Aircraft Icing
Conceived and published by NASA, this
web site contains free icing training courses and resources for
pilots who want to learn more about aircraft icing and what they
can do about it. Two courses are presented...
"Make sure you are aware of where there is icing and
where it is safe. Knowing the answers to these two questions PRIOR
to flying will reduce the time needed to decide the best course of
action if icing conditions are encountered. Remember, in icing
conditions, time is critical."
