Definition
A radio receiver designed to pick up voice transmissions on the aviation communications frequency bands, primarily the VHF range of 118.000 to 136.975 MHz used for air traffic control and air-to-air communication.
Plain English
The part of an aircraft radio that listens for incoming voice messages, such as instructions from a controller or calls from another aircraft.
Context Anchor
Seen in aircraft radio equipment discussions, especially when separating the radio’s listening function from its sending function.
Derivation
From Latin communicare, meaning 'to share' or 'to make common,' and Latin recipere, 'to take back' or 'receive.' Together it describes a device that takes in shared voice messages sent over the air.
Why Pilots Care
It is the only way to receive real-time instructions, traffic advisories, and clearances needed for safe flight in controlled airspace.
Intuition Check
A communications receiver does not send your voice; it only receives incoming radio signals. The transmitter is the part that sends.
Example Sentence 1
After switching tanks, the pilot noticed the communications receiver had gone silent and reached up to check the volume and squelch.
Example Sentence 2
Static interference on the communications receiver forced the crew to request a repeat of the approach clearance.
