Airband or aircraft band is the name for a group of frequencies in the VHF radio spectrum allocated to radio communication in civil aviation, sometimes also referred to as VHF, or phonetically as "Victor". Different sections of the band are used for radionavigational aids and air traffic control. [ 1][ 2][ 3]
Common traffic advisory frequency ( CTAF) is the name given to the VHF radio frequency used for air-to-air communication at United States, and Australian non-towered airports . Many towered airports close their towers overnight, keeping the airport open for cargo operations and other activity. Pilots use the tower frequency to coordinate their ...
Automatic terminal information service, or ATIS, is a continuous broadcast of recorded aeronautical information in busier terminal areas. ATIS broadcasts contain essential information, such as current weather information, active runways, available approaches, and any other information required by the pilots, such as important NOTAMs.
Air-to-ground communication was first made possible by the development of two-way aerial telegraphy in 1912, soon followed by two-way radio. By the Second World War, radio had become the chief medium of air-to-ground and air-to-air communication. Since then, transponders have enabled pilots and controllers to identify planes automatically ...
Coordinates: 42.73517°N 71.48056°W. Boston Air Route Traffic Control Center ( ZBW; in radio communications, "Boston Center") is one of 22 Air Route Traffic Control Centers in the United States, located in Nashua, New Hampshire . The primary responsibility of ZBW is the separation of overflights, and the expedited sequencing of arrivals and ...
Radiotelephony procedure (also on-air protocol and voice procedure) includes various techniques used to clarify, simplify and standardize spoken communications over two-way radios, in use by the armed forces, in civil aviation, police and fire dispatching systems, citizens' band radio (CB), and amateur radio . Voice procedure communications are ...
ACARS. In aviation, ACARS ( / ˈeɪkɑːrz /; an acronym for Aircraft Communications Addressing and Reporting System) is a digital datalink system for transmission of short messages between aircraft and ground stations via airband radio or satellite. The protocol was designed by ARINC and deployed in 1978, [ 1] using the Telex format.
Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth, either the vessel or an obstruction. [1] [2] Like radiolocation, it is a type of radiodetermination . The basic principles are measurements from/to electric beacons, especially.
