Ohjauspiiriä
Ohjauspiiriä refers to the control area or control zone in the context of aviation. It is a designated area of airspace where air traffic control services are provided to ensure the safe, orderly, and efficient flow of air traffic. The control area is typically surrounded by an outer marker (OM) and an inner marker (IM), which are navigation aids used to define the boundaries of the control zone. Air traffic controllers monitor and guide aircraft within this area, providing instructions and clearances to pilots to maintain separation and avoid collisions.
The control area is further divided into several sectors, each managed by a specific air traffic controller.
Air traffic controllers use various tools and technologies to manage the control area, including radar systems,
