Climbing Through the Layers: Understanding Flight LevelsThis blog post explores the concept of **Flight Levels (FL)** in aviation — standardized altitudes used above 18,000 feet for safe and consistent aircraft separation. It explains why flight levels are used instead of altitudes, outlines common FLs, and introduces rules like the **semi-circular rule** for air traffic flow. Real-world examples and visuals help demystify how pilots and ATC coordinate at high altitudes.
