List Of Area Control Centers
Area control centers (ACCs) control IFR air traffic in their flight information region (FIR). The current list of FIRs and ACCs is maintained by the International Civil Aviation Organization (ICAO). Note that the cited ICAO source gives the shapefile coordinates for each FIR, and also its page source gives a list of current ACCs in text form. The following is the alphabetic list of all ACCs and their FIRs : See also * |
Area Control Center
In air traffic control, an area control center (ACC), also known as a center or en-route center, is a facility responsible for controlling aircraft flying in the airspace of a given flight information region (FIR) at high altitudes between airport approaches and departures. In the US, such a center is referred to as an air route traffic control center (ARTCC). A center typically accepts traffic from — and ultimately passes traffic to — the control of a Terminal control area, terminal control center or another center. Most centers are operated by the national governments of the countries in which they are located. The general operations of centers worldwide, and the boundaries of the airspace each center controls, are governed by the International Civil Aviation Organization (ICAO). In some cases, the function of an area control center and a terminal control center are combined in a single facility. For example, NATS Holdings, NATS combines the London Terminal Control Ce ...

Mataveri International Airport
Mataveri International Airport or Isla de Pascua Airport is at Hanga Roa on Rapa Nui / (Easter Island) (''Isla de Pascua'' in Spanish). The most remote airport in the world (defined as distance to another airport), it is from Santiago, Chile (SCL) which has scheduled flights to it on the Chilean carrier LATAM Chile. The runway starts just inland from the island's southeast coast at Mataveri, and nearly reaches the west coast, almost separating the mountain of Rano Kau from the rest of the island. The airport is the main point of entry for visitors to Easter Island. It has a transit lounge that was formerly used by passengers continuing to or returning from Papeete, Tahiti, which was serviced by LATAM until June 2020. History Scheduled services from the Chilean mainland started in 1967 with a monthly Douglas DC-6B propliner flight operated by LAN-Chile that took nine hours, using a runway extended and paved for the use as a U.S. base. In 1970, services were upgraded with weekly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminal Control Area
In aviation, a terminal control area (TMA, or TCA in the U.S. and Canada), is a designated area of controlled airspace surrounding a major airport where there is a high volume of traffic. TMA airspace is normally designed in a circular configuration centered on the airport, and differs from a control area in that it includes several levels of increasingly larger areas, creating an "upside-down wedding cake" shape. In Canada, the inner circle of the TCA is generally a 12 NM radius from the airport geographic center based at 1200 feet AGL, with an intermediate circle at 35 NM based at 2200 feet AGL, and an outer limit at 45 NM radius based at 9500 feet AGL. In Canada, the TCA is normally designated as class B, C or D. In the U.S., the airspace of a TCA is typically designated as class B. In the U.K., the airspace of a TMA is usually designated as class A, D or E. In Australia, "terminal airspace" is not used both in common vernacular or publication and legislation. However, th ...

Control Zone
A control zone (CTR) in aviation is a volume of controlled airspace, usually situated below a control area, normally around an airport, which extends from the ''surface'' to a ''specified upper limit'', established to protect air traffic operating to and from that airport. Because CTRs are, by definition, controlled airspace, aircraft can only fly in it after receiving a specific clearance from air traffic control. This means that air traffic control at the airport know exactly which aircraft are in that airspace, and can take steps to ensure aircraft are aware of each other, either using separation or by passing traffic information. In the USA the term control zone is no longer used and has been replaced by airspace class D. Typically it extends 5 miles in diameter with a height of 2500 ft AGL (above ground level) around small commercial airports. Aircraft are required to establish radio contact with the control tower before entering and to maintain in contact while in class ...

Control Area (aviation)
In aviation, a control area (CTA) is the volume of controlled airspace that exists in the vicinity of an airport. It has a specified lower level and a specified upper level. It usually is situated on top of a control zone and provides protection to aircraft climbing out from the airport by joining the low-level control zone to the nearest airways. In the UK they are generally class A, D or E. Control areas are particularly useful where there are busy airports located close together. In this case a single CTA will sit over all of the individual airports' CTRs. In larger-scale cases, this is known as a terminal manoeuvring area (TMA).

Flight Information Region
In aviation, a flight information region (FIR) is a specified region of airspace in which a flight information service and an alerting service (ALRS) are provided. The International Civil Aviation Organization (ICAO) delegates which country is responsible for the operational control of a given FIR. FIRs are the largest regular division of airspace in use in the world today, and have existed at least since 1947. Smaller countries' airspace is encompassed by a single FIR; larger countries' airspace is subdivided into a number of regional FIRs. Some FIRs encompass the territorial airspace of several countries. Oceanic airspace is divided into oceanic information regions and delegated to a controlling authority bordering that region. The division among authorities is done by international agreement through the International Civil Aviation Organization (ICAO). There is no standard size for FIRs–some are merely vertical extensions of their respective countries, however small they m ...

Airway (aviation)
In the United States, airways or air routes are defined by the Federal Aviation Administration (FAA) in two ways: "VOR Federal airways and Low/Medium Frequency (L/MF) (Colored) Federal airways" These are designated routes which aeroplanes fly to aid in navigation and help with separation to avoid accidents. Airways are defined with segments within a specific altitude block, corridor width, and between fixed geographic coordinates for satellites navigation system, or between ground-based radio transmitter navigational aids (navaids; such as VORs or NDBs) or the intersection of specific radials of two navaids. United States To guide airmail pilots on their delivery routes, the United States Postal Service constructed the first airways in the United States, the Contract Air Mail routes. These airways were between major cities and identified at night by a series of flashing lights and beacons which pilots flew over in sequence to get from one city to the next. Intermediate ...

Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advisories'' (known as ''flight infor ...

Airspace
Airspace is the portion of the atmosphere controlled by a country above its territory, including its territorial waters or, more generally, any specific three-dimensional portion of the atmosphere. It is not the same as aerospace, which is the general term for Earth's atmosphere and the outer space in its vicinity. Within the United States: * Controlled airspace exists where it is deemed necessary that air traffic control has some form of positive executive control over aircraft flying in that airspace (however, air traffic control does not necessarily control traffic operating under visual flight rules (VFR) within this airspace). Airspace may be further subdivided into a variety of areas and zones, including those where there are either restrictions on flying activities or complete prohibition of flying activities. Horizontal boundary By international law, a state "has complete and exclusive sovereignty over the airspace above its territory", which corresponds with t ...

Hong Kong (Area Control Centre)
Hong Kong (Area Control Centre) is one of two key area control centres in the Pearl River Delta and is under the Hong Kong Civil Aviation Department. HK ACC is based out of the control tower at Hong Kong International Airport. From this ACC, air traffic controllers provide en route and terminal control services to aircraft in the Hong Kong Flight Information Region (FIR). The Hong Kong FIR airspace covers the waters off Hong Kong to the south, southeast and southwest. This does not include the airspace and immediate waters off the mainland China and Macau (under Guangzhou FIR). HK ACC does handle flight in and out of Macau International Airport. Aerodrome classes The HKG ACC assumes control of the following classes of airports * VHHH – Chek Lap Kok * VHSK – Sek Kong Airfield * VHSS – Shun Tak Heliport * HK07 – Central Government Heliport * VMMC - Macau International Airport * XZM - Macau Heliport * RCLM - Dongsha Airport Dongsha Airport is located on Pratas Island ...
