Definition
A single radio unit that both transmits and receives voice communications on aviation frequencies, typically in the VHF band (118.0–136.975 MHz), allowing a pilot to talk to air traffic control, ground stations, and other aircraft on a selected frequency.
Plain English
A two-way aviation radio. One box that lets you both talk and listen on the same chosen frequency.
Context Anchor
Seen in cockpit radio and avionics discussions, especially when selecting a radio frequency before making or receiving a call.
Derivation
The word transceiver is a blend of transmitter and receiver. It exists because the same unit performs both functions, so one word covers what would otherwise take two.
Why Pilots Care
Enables immediate two-way voice contact required for clearances, traffic advisories, and emergencies.
Intuition Check
Do not think of it as only a receiver, like a radio you listen to. A communications transceiver is two-way: it sends your voice out and receives other voices back.
Example Sentence 1
Before taxi, the pilot tuned the communications transceiver to ground control and requested taxi clearance.
Example Sentence 2
When the controller issued a new heading, the pilot acknowledged it over the communications transceiver.
