Definition
Two-way radio voice contact between aircraft in flight and ground-based facilities such as air traffic control, flight service stations, or company operations. It is the primary spoken channel used to exchange clearances, instructions, position reports, weather, and advisories between pilots and personnel on the ground.
Plain English
Talking by radio between people in the air and people on the ground. The pilot speaks to a controller or station on the ground, and they speak back, using a voice radio rather than text or data link.
Context Anchor
Seen in NextGen discussions when traditional spoken radio is compared with newer ways of sending flight information electronically.
Why Pilots Care
Voice remains the primary real-time method for instructions, clarifications, and emergencies even as NextGen adds data options to ease radio congestion.
Intuition Check
Do not read this as any conversation that happens on the ground. In this context, it means radio voice communication between an aircraft in the air or on the airport surface and an aviation facility on the ground.
Example Sentence 1
Over remote oceanic areas, air/ground voice communications can be unreliable, which is one reason data link is being expanded under NextGen.
Example Sentence 2
NextGen procedures still rely on air/ground voice communications for urgent changes while routing routine clearances via data link.
