lennukõrgus

Lennukõrgus, also known as flight level or altitude, refers to the vertical distance of an aircraft above a specific reference point, typically mean sea level (MSL) or a standard datum plane. It is a critical parameter in aviation for various reasons, including safety, navigation, and air traffic control.

In aviation, altitude is measured using various instruments such as altimeters, which provide pilots with real-time information about the aircraft's height above the ground or a reference point. Altimeters can be set to different reference points, such as QNH (pressure at mean sea level) or QFE (pressure at the aerodrome reference point), depending on the phase of flight and the specific requirements of the airspace.

Flight levels are standardized altitudes used in controlled airspace, typically above 18,000 feet (5,500 meters) MSL. They are expressed in hundreds of feet, with the prefix "FL" followed by the altitude in hundreds. For example, FL350 corresponds to 35,000 feet MSL. Flight levels help to avoid confusion and ensure consistent communication between air traffic controllers and pilots.

Lennukõrgus plays a crucial role in collision avoidance, as maintaining appropriate separation between aircraft is essential for safe flight operations. Additionally, altitude is a key factor in weather avoidance, as pilots must be aware of weather conditions at different altitudes to plan their routes and avoid hazardous weather phenomena.

In summary, lennukõrgus is a fundamental concept in aviation that encompasses the vertical distance of an aircraft above a reference point, measured using altimeters, and expressed in standardized flight levels. It is vital for safety, navigation, and air traffic control, enabling pilots to maintain appropriate separation, avoid collisions, and navigate through various airspaces and weather conditions.
