Freezing rain-vs-Severe Icing

[Sammy]

I was always taught that freezing rain was severe icing. ie They were one in the same. Can anyone direct me where it is WRITTEN as such or not as such. Thank you.

Severe icing is defined as any icing that overwhelms the airplane's anti-icing systems, or when ice accumulates on parts of the aircraft that don't usually build ice.

Freezing rain will usually build clear ice behind the boots or heated leading edge of the wing, so it is severe icing. The only exception is when it is just light freezing drizzle and builds in the usual places.

That would just about define any icing conditions found while flying a pneumatic boot equiped caravan. When visible moisture and temps below 0 C meet, I get more nervous than a cat in a room full of rocking chairs.

I hate ICE too, even when I got boots. Makes me all tight inside.

Common mistake.

Freezing rain is a type of precipitation.

Severe icing is a rate of accumulation.

While it stands to reason that a particular rate of accumulation (severe icing) may be likely in certain types of precipitation, that does not mean they are one in the same.

They aren't.

True holmes. I can see flying over an airport with freezing rain at the surface. I can see flying through ice pellets from freezing rain from above, but any pirep of severe icing is going to be enough to shut that mother down, as far as our pilot group and management is concerned. Seen it happen. Like it. Will do it tommorow. Without loosing one minute of sleep.
