MIL-STD-810G Method 521.3 Icing and Freezing Rain Test

Quote:
Icing and freezing rain occurs when the air is saturated with super-cooled water droplets which forms rime ice and/or glaze ice. Rime ice is a white or milky accumulation and is lighter, softer and less transparent than glaze ice. Glaze ice is a generally clear hard coating of ice. Rime forms when super-cooled water drops freeze on exposed surfaces. Glaze ice forms from a film of super-cooled water vapor freezing as a layer.

Inadvertent flight into icing often (but not always) requires prompt action. If the airplane does not have complete ice protection, the options are to climb, descend, or turn around. Climbing only works if the performance is still there to do it. Descending only works if there is enough room between the freezing level and the ground. It pays to think through the possibilities beforehand.
