Cold stratocumulus

Added on: March 10, 2014         Duration: 12 minutes

During the cold season, it is quite common to find a blanket of stratocumulus clouds in the wake of a strong cold front. Stratocumulus clouds rarely have a depth of more than a few thousand feet. Even when it is cold enough for structural icing, pilots are often tempted to descend or climb through this rather “thin” layer of clouds. While some stratocumulus decks can be quite harmless even for an unprotected aircraft, they can dish out some of the most intense structural icing that can quickly overwhelm many certified ice protection systems (IPS). In this workshop, we’ll examine the icing environment for a cold stratocumulus deck that produced severe icing conditions as reported by the crew of two Boeing 767s.
