Two-way communication between aircraft and stations or locations on the surface of the earth.

Voice Communications

Voice/audio communications between an aircraft and the ground are traditionally accomplished using radio telephony, broadcasting and receiving on:

  • UHF
  • VHF
  • HF

Alternatively voice communications can be conducted using SATCOM, including VOIP through the Internet.

Data Communications

Data can be passed between an aircraft and a ground station using:

Visual Communications

Communications can be accomplished visually using, for example, and Aldis[1] Lamp to flash messages between aircraft and ground stations in Morse Code or through standard conventions associated with emergency situations.

Light signals and pyrotechnics can be used to issue simple instructions to aircraft in flight or on the manoeuvring area. This is sometimes used by aerodrome control towers as a backup in case of radiocommunication failure. For example, a steady green light means "Cleared to land" for traffic in the air and "Cleared for take-off" for traffic on the ground. A red pyrotechnic would mean "Notwithstanding any previous instructions, do not land for the time being".
