Freezing rain - Wikipedia, the free encyclopedia
In all my flying I have only experienced icing out of visible moisture (cloud) a handful of times.
With an aircraft flying fast in a straight line I have found the area of such precipitation to be small.
Noted in the Helicopter incident and the ATR-72 crash featured in the above link both appear to have remained in a confined area the ATR in a hold.
A student is unlikely to be sent on a solo cross country where he is likely to inadvertantly enter cloud or on days with CB activity.
As in any icing get out fast and beware of days when you know you will carry it down to the ground.
