Definition
The exchange of information between pilots and air traffic controllers (or other aircraft) using spoken transmissions over aviation radio frequencies, as opposed to text-based or digital data link methods.
Plain English
Talking to ATC or other pilots over the radio, instead of sending typed messages through a data link system.
Context Anchor
In the NextGen system, this term often appears when comparing traditional radio talking with newer digital message systems used between aircraft and air traffic control.
Derivation
Voice comes from the Latin word vox, meaning sound or speech. Communication comes from Latin words meaning to share or make common. Together, the term points to shared information carried by spoken words.
Why Pilots Care
Voice channels can become congested; NextGen aims to offload routine messages to data links.
Intuition Check
Do not read this as casual conversation. In aviation, voice communications means purposeful spoken messages that move flight information, instructions, or safety-critical reports between people.
Example Sentence 1
During the oceanic crossing, the crew used data link for routine reports but switched to voice communications when requesting an immediate altitude change.
Example Sentence 2
NextGen reduces the need for voice communications by allowing certain clearances via data link.
