Icing reports do vary; absolutely icing reports vary. This is ALWAYS the case with PIREPS. Moreover, the nature of what's reported is subjective according to the individual experience level of the pilot. What is light to one pilot may be moderate to another, even in the same type aircraft. What is light in one type aircraft may be moderate or severe in another type aircraft.

Surely the categorisation of icing severity HAS to be based on the rate of accumulation and not the ability of a specific aircraft to deal with ice accumulations? I appreciate a pilot report on icing is subjective as in turbulence reports.
