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.
