❄️ FREEZING RAIN & FREEZING DRIZZLE ⚠️✈️
Freezing rain and freezing drizzle are a major threat in aviation, and no aircraft should ever attempt to fly into these conditions. They will always lead to rapid buildup of clear ice on all aircraft surfaces. 🧊
The conditions required for this are supercooled rain droplets (temperature very close to 0°C), a cold aircraft airframe, and droplets falling from a relatively warm layer aloft into colder air below. 🌧❄️
These conditions are most often met just ahead of a warm front during winter. 🌡
This setup is known as the Rain Ice Triangle, and it creates severe icing conditions that must always be avoided. ⚠️
The best way to escape is to climb higher into the warmer layer above — simply flying through the area or turning back should never be considered, as safe conditions can often be found just a few thousand feet higher. ⬆️✈️
