FL200, or Flight Level 200, refers to an altitude of 20,000 feet above sea level. It is commonly used in aviation to indicate the cruising altitude of aircraft. At this level, pilots and air traffic controllers communicate using flight levels instead of feet to avoid confusion, especially in busy airspace. In the context of aviation, air traffic control plays a crucial role in managing flights at FL200. This altitude is often used for commercial flights, allowing for efficient routing and separation from other aircraft. Understanding flight levels like FL200 is essential for safe and effective air travel.
