Lennonvalvonta

Lennonvalvonta, also known as flight monitoring or air traffic surveillance, refers to the continuous observation and tracking of aircraft during flight. This essential aviation function is primarily carried out by air traffic control (ATC) facilities. Lennonvalvonta utilizes a combination of radar systems, including primary radar and secondary surveillance radar (SSR), to detect aircraft positions, altitudes, and identities. Transponders on board aircraft transmit identification codes and altitude information, which are crucial for accurate monitoring.

The primary objective of lennonvalvonta is to ensure the safe separation of aircraft, preventing collisions in the airspace. Controllers monitor aircraft movements, issue instructions for maintaining course, altitude, and speed, and manage traffic flow, especially in busy terminal areas and en route airspace. Beyond safety, lennonvalvonta contributes to efficient air traffic management by optimizing routes and minimizing delays. It also plays a vital role in search and rescue operations by providing crucial information about an aircraft's last known position.

Modern lennonvalvonta systems incorporate advanced technologies such as Automatic Dependent Surveillance-Broadcast (ADS-B), which allows aircraft to broadcast their position and other flight data directly to ground stations and other aircraft. This enhances situational awareness for both controllers and pilots. The information gathered through lennonvalvonta is critical for maintaining the order and safety of the global air transportation system.
