Lähenemiskontroll

Lähenemiskontroll, often translated as "approach control" or "proximity control," is a concept primarily used in aviation to describe the process of managing aircraft movements within a defined airspace to ensure safe separation and efficient traffic flow. This control is exercised by air traffic controllers, typically located in approach control units or control towers.

The primary objective of lähenemiskontroll is to guide arriving and departing aircraft safely through the busy airspace surrounding an airport. This involves sequencing aircraft for landing, maintaining safe vertical and horizontal distances between them, and providing instructions for altitude, heading, and speed adjustments. For departing aircraft, lähenemiskontroll ensures they are safely integrated into the en route structure or other sectors of air traffic control.

Lähenemiskontroll utilizes radar and other surveillance systems to track aircraft positions. Controllers communicate with pilots via radio to issue clearances and advisories. The specific procedures and airspace structures involved in lähenemiskontroll are defined by aviation authorities and vary depending on the size and complexity of the airport and its surrounding airspace. Effective lähenemiskontroll is crucial for preventing collisions, minimizing delays, and optimizing the use of airspace. It is a critical component of the overall air traffic management system.
