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.
The datalink control and display unit (DCDU) on an Airbus A330, the pilot interface for sending and receiving CPDLC messages. Controller–pilot data link communication (CPDLC) is a means of communication between controller and pilot, using data link for ATC communication. At the highest level, the concept is simple, with the emphasis on the ...
ACARS as a term refers to the complete air and ground system, consisting of equipment on board, equipment on the ground, and a service provider. On-board ACARS equipment [4] consists of end systems with a router, which routes messages through the air-ground subnetwork. Ground equipment is made up of a network of radio transceivers managed by a ...
Conceptual of the ADS-B system, illustrating radio links between aircraft, ground station and satellite. Automatic Dependent Surveillance–Broadcast (ADS-B) is an aviation surveillance technology and form of electronic conspicuity in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts ...
Remote and virtual tower (RVT) is a system based on air traffic controllers being located somewhere other than at the local airport tower, and still able to provide air traffic control services. [12] [13] [14] Displays for the air traffic controllers may be live video, synthetic images based on surveillance sensor data, or both.
Communication, i.e. aviation communication, refers to communication between two or more aircraft, the exchange of data or verbal information between aircraft and air traffic control and the ground based communication infrastructure of the ATM network (like the aeronautical fixed service). [2]
Virtual Air Traffic Simulation Network. Virtual Air Traffic Simulation Network (VATSIM) is a nonprofit organization that operates an online flight-simulation network noted for its active membership and realism. [2][3][4][5] Users are able to connect to VATSIM and fly aircraft as a pilot, or direct traffic as an air traffic controller in what ...
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 ...
