Study Notes
Communication in Air Traffic Services
- VOLMET is a routine broadcast of meteorological information for aircraft in flight, providing information for a group of aerodromes to alert pilots of changes in weather and forecast conditions.
Aeronautical Stations and Centers
- Aeronautical stations are starting or ending points of communication, including aeronautical fixed stations, aircraft stations, or AFTN stations.
- Aeronautical centers are stations that relay or retransmit communication, such as communication centers or AFTN centers.
Communication Methods
- Communication can be two-way (air-ground, air-air, or ground-ground) or one-way (air to ground).
- Readback is a procedure where the receiving station repeats a received message to the transmitting station to confirm correct reception.
- Blind transmission is a transmission from one station to another when two-way communication cannot be established, but it is believed that the called station can receive the transmission.
- Broadcast is a transmission of information not addressed to a specific station.
Communication Requirements
- ATS requirements for safe communication include stating the structure of the communication domain, major substructures, and aeronautical communication services.
- The purpose of ATIS and VOLMET is to provide pilots with necessary information for safe flight.
Communication Systems
- Fiber optic communication uses light signals, which are immune to electrical interference, and allow for lower-power transmitters.
- Wireless transmission involves the transfer of information through electromagnetic waves, which can be affected by diffraction, scattering, and reflection.
Microwave Links
- Microwaves are used for point-to-point communications due to their small wavelength, allowing for conveniently-sized antennas to direct them in narrow beams.
Satellite Communication
- Communications satellites are used for multiple applications, with over 2,000 satellites in Earth's orbit, used by both private and government organizations.
- Satellites can be geostationary or low/polar orbiting, and UHF communication uses direct waves with a theoretical range up to 200 NM.
Selective Calling System (SELCAL)
- SELCAL is a selective-calling system that allows a ground radio operator to alert an aircrew that the operator wishes to communicate with that aircraft.
Controller Pilot Data Link Communication (CPDLC)
- CPDLC is a means of communication between controller and pilot using data link for communication, facilitating routine/frequent types of messages and requests.
- CPDLC is used in conjunction with existing voice communication, reducing communication problems and errors, and resolving misunderstandings due to poor voice quality.
