Whether you are flying IFR or VFR, it is important to appreciate the danger of flying into freezing rain. This is especially important advice to instrument pilots. Their training suggests that upon encountering freezing rain, they should initiate a climb. It is explained to them that they can escape the freezing rain by climbing into warmer air aloft. In fact, they are promised that they will eventually reach an altitude fairly quickly with a temperature that is warmer than 0 degrees Celsius eliminating the risk of structural icing. While there is nothing inherently wrong with this advice, it fails to tell the complete story. Freezing rain typically has a very shallow depth and often only extends a few hundred feet above the surface. In this workshop we’ll use a Skew-T log (p) diagram to identify freezing rain potential as well as the depth of the freezing rain layer.
