Tasks Center

The area control center (ACC) position is responsible for controlling aircraft flying in the airspace within a flight information region (FIR). The ACC is typically controlling flights in almost every level, at low and high altitudes. The Center typically accepts traffic from - and ultimately passes traffic to - an approach/arrival position or another ACC station.

Just as the TMA controllers, the ACC controller has various tool at their disposal. They can use STARs, transitions, and radar vectors to achieve the necessary separation. To maintain this separation, speeds are typically used, which the pilot must adhere to. 

note, that above the conversion level (FL280) Mach Numbers will be used! 

The work of a centre controller can typically be divided into two types. On the one hand, there is work in what is known as lower airspace, and on the other, work in what is known as upper airspace. 

Lower airspace is typically characterised by many climb and descend movements to and from TMAs. Upper airspace, on the other hand, is more known for overflights and a few climb and descend movements.
