Freezing Level
Definition
The altitude in the atmosphere where the temperature first drops to 0 degrees Celsius. Important for icing risk assessment: structural icing occurs when flying through visible moisture at or above the freezing level.
Why Freezing Level Matters for Pilots
Weather concepts like Freezing Level appear frequently on both FAA and EASA knowledge exams. More importantly, understanding Freezing Level helps pilots make sound go/no-go decisions and avoid hazardous conditions in flight. Weather-related accidents remain a leading cause of general aviation incidents.
Exam Tip
This concept is commonly tested in meteorology-related questions on FAA and EASA exams. Make sure you can explain Freezing Level in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
