Most encounters with airframe ice occur while flying in clouds when the temperature at your altitude is at or below 0 degrees Celsius. Therefore, staying in cloud-free air above the cloud tops or in between cloud layers is critical when attempting to minimize your exposure to airframe ice. Many weather systems during the cold season are too deep to safely climb and remain on top. However, the clouds in these weather systems are typically layered and rarely have a continuous vertical extent. This gives the pilot the option of flying in between layers assuming you know where they are located. In this workshop, we’ll use the Skew-T log (p) diagram to help identify the potential for clear air between two distinct cloud layers.
