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). The following is the alphabetic list of all ACCs and their FIRs as of October 2011 [update] :
Flight Information Regions for Italy. 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. [1] The International Civil Aviation Organization (ICAO) delegates which country is responsible for the operational control of a given FIR. FIRs ...
An ARTCC controls aircraft flying in a specified region of airspace, known as a flight information region (FIR), typically during the en route portion of flight. The purpose of control is to promote the safe, orderly, and expeditious flow of air traffic [ 2 ] and prevent collisions.
The flight information region controlled by a center may be further administratively subdivided into areas comprising two to nine sectors. Each area is staffed by a set of controllers trained on all the sectors in that area. Sectors use distinct radio frequencies for communication with aircraft.
However, a country may, by international agreement, assume responsibility for controlling parts of international airspace, such as those over the oceans. Such airspace in respect of which a country is responsible under the International Civil Aviation Organization (ICAO) for operational control is called a Flight Information Region (FIR). For a ...
The AFIS officer (abbreviated AFISO) provides flight information service including, traffic information, meteorological information, information on runway state and other information useful for the safe and efficient conduct of flight. The pilot must use this information and make up his own mind about certain aspects e.g. flight route. In TIZ ...
The boundary between flight information regions and UIRs vary by country, but is usually above FL245 (24,500 feet) or FL660 (66,000 feet) depending on jurisdiction. [2] They are used to manage high level traffic such as commercial airliners and military aircraft. Some countries may have their boundary below FL245.
Some of the free software mentioned here does not have detailed maps (or maps at all) or the ability to follow streets or type in street names (no geocoding). However, in many cases, it is also that which makes the program free (and sometimes open source [ 1 ] ), avoid the need of an Internet connection, [ 2 ] [ 3 ] [ 4 ] and make it very ...
