NationMaster - Encyclopedia: Area Control Center

In air traffic control, an Area Control Center (ACC), also known as a Center, is a facility responsible for controlling instrument flight rules aircraft en route in a particular volume of airspace (a Flight Information Region) at high altitudes between airport approaches and departures. In the United States, such a Center is referred to as an Air Route Traffic Control Center (ARTCC). Image File history File links No higher resolution available. ...

A Center typically accepts traffic from, and ultimately passes traffic to, the control of a Terminal Control Center or of another Center. Most Centers are operated by the national governments of the countries in which they are located. The general operations of Centers world-wide, and the boundaries of the airspace each Center controls, are governed by the International Civil Aviation Organization.

In some cases, the function of an Area Control Center and a TRACON are combined in a single facility such as a CERAP.

Airspace means the portion of the atmosphere controlled by a particular country on top of its territory and territorial waters or, more generally, any specific three-dimensional portion of the atmosphere. ... Visual flight rules (VFR) are a set of aviation regulations under which a pilot may operate an aircraft in weather conditions sufficient to allow the pilot, by visual reference to the environment outside the cockpit, to control the aircrafts attitude, navigate, and maintain safe separation from obstacles such as...

Subdivision of airspace into sectors

The Flight Information Region controlled by a Center may be further administratively subdivided into sectors; each sector may use a distinct set of communications frequencies and personnel. An aircraft passing from one sector to another may be handed off and requested to change frequencies to contact the next sector controller. Sector boundaries are specified by an aeronautical chart. A Flight Information Region (FIR) is an airspace with specific dimensions, in which an information service and an alert service are provided. ... An aeronautical chart is a map designed to assist in navigation of aircraft, much as nautical charts do for watercraft, or a roadmap for drivers. ...

Center operations

Air traffic controllers working within a Center communicate via radio with pilots of instrument flight rules aircraft passing through the Center's airspace. A Center's communication frequencies (typically in the very high frequency amplitude modulation aviation bands, 118 MHz to 137 MHz, for overland control) are published in aeronautical charts and manuals, and will also be announced to a pilot by the previous controller during a hand-off.

Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. ... Note: This article title may be easily confused with AirBand The airband or air band is the band of frequencies used for radio communication in aviation. ...

In addition to radios to communicate with aircraft, Center controllers have access to communication links with other Centers and TRACONs. In the United States, Centers are electronically linked through the National Airspace System, which allows nationwide coordination of traffic flow to manage congestion. Centers in the United States also have electronic access to nationwide radar data.

Controllers use radar to monitor the progress of flights and instruct aircraft to perform course adjustments as needed to maintain separation from other aircraft. Aircraft with which a Center has made radar contact can be readily distinguished by their transponders. Pilots may also request altitude adjustments or course changes to avoid turbulence or adverse weather conditions. This long range radar antenna, known as ALTAIR, is used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on the Kwajalein atoll. ... Separation may refer to a several different subjects: In chemistry, separation refers to the separation process. ... In telecommunication, the term transponder (sometimes abbreviated to XPDR or TPDR) has the following meanings: An automatic device that receives, amplifies, and retransmits a signal on a different frequency. ... In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by chaotic, stochastic property changes. ... Weather is a term that encompasses phenomena in the atmosphere of a planet. ...

Controllers can assign routing relative to location fixes derived from latitude and longitude, or from radionavigation beacons such as VORs. See also Airway; VORs and aerial highways. Latitude, usually denoted symbolically by the Greek letter phi, , gives the location of a place on Earth north or south of the equator. ... Longitude, sometimes denoted by the Greek letter Î» (lambda),[1][2] describes the location of a place on Earth east or west of a north-south line called the Prime Meridian. ...

Typically, Centers have advance notice of a plane's arrival and intentions from its prefiled flight plan. Flight plans are plans filed by pilots with the local Aviation Authority (e. ...

Oceanic air traffic control

Some Centers have ICAO-designated responsibility for airspace located over an ocean, the majority of which is international airspace. Because substantial volumes of oceanic airspace lie beyond the range of ground-based radars, oceanic airspace controllers have to estimate the position of an airplane from pilot reports and computer models (procedural control), rather than observing the position directly (radar control, also known as positive control). Pilots flying over an ocean can determine their own positions accurately using the Global Positioning System and can supply periodic updates to a Center. See also Air traffic control: Radar Coverage. Animated map exhibiting the worlds oceanic waters. ... Procedural control is a method of providing air traffic control services without the use of radar. ... Radar control is a method of providing air traffic control services with the use of radar. ... The Global Positioning System (GPS) is currently the only fully functional Global Navigation Satellite System (GNSS). ... Air Traffic Control Towers (ATCTs) at Amsterdams Schiphol Airport (Netherlands) Air traffic control (ATC) is a service provided by ground-based controllers who direct aircraft on the ground and in the air. ...

A Center's control service for an oceanic FIR may be operationally distinct from its service for a domestic overland FIR over land, employing different communications frequencies, controllers, and a different ICAO code.

Pilots typically use high frequency radio instead of very high frequency radio to communicate with a Center when flying over the ocean, because of HF's relatively greater propagation over long distances. High frequency (HF) radio frequencies are between 3 and 30 MHz. ... Very high frequency (VHF) is the radio frequency range from 30 MHz (wavelength 10 m) to 300 MHz (wavelength 1 m). ... Wave propagation refers to the ways waves travel through a medium (waveguide). ...
