Definition
The radios and related avionics installed in an aircraft that allow the pilot to talk with air traffic control, other aircraft, and ground stations. In civil aviation this primarily means VHF transceivers operating in the aviation voice band, along with audio panels, microphones, headsets, and speakers that route and control the audio.
Plain English
The radio gear in the aircraft that lets the pilot talk to controllers and other pilots, and hear them back.
Context Anchor
Seen when describing aircraft systems, cockpit equipment, preflight checks, and communication between the aircraft and people on the ground or in other aircraft.
Derivation
Communication comes from a Latin word meaning “to share” or “make common.” Equipment comes from an older word meaning “to fit out or supply.” Together, the term means the supplied gear that lets information be shared during flight.
Why Pilots Care
Working communication equipment is required for flight in controlled airspace and is essential for receiving clearances, traffic advisories, and weather updates. A radio failure changes how the flight must be conducted and can require following lost-communication procedures.
Intuition Check
Do not read this as just any device that can communicate, like a personal phone. In an aviation context, communication equipment means the flight-related gear used to exchange needed information during aircraft operation.
Example Sentence 1
Before starting the engine, the pilot tested the communication equipment by tuning the ground frequency and checking that transmissions were clear.
Example Sentence 2
Loss of communication equipment during flight required the pilot to follow standard lost-comm procedures.
