Definition
A computer-based communication system used in FAA Air Route Traffic Control Centers (ARTCCs) that allows en route controllers to manage all of their voice communications -- both air-to-ground (radio) and ground-to-ground (landline) -- through a single touch-screen interface at the controller's workstation.
Plain English
It is the system controllers use to talk to pilots on the radio and to other controllers on phone lines, all from one screen at their console. Instead of juggling separate radios and phones, they tap buttons on a touch panel to select who they are talking to.
Context Anchor
Pilots may hear about the Voice Switching And Control System during reports of air traffic control communication problems, equipment outages, or backup communication procedures.
Why Pilots Care
It keeps radio communications reliable and efficient, reducing the chance of missed calls or frequency confusion during flight.
Analogy
It works somewhat like a control-room switchboard: the controller selects the voice connection needed, and the system connects the right people over the right line or radio channel.
Intuition Check
Do not read “control system” as a system that controls the airplane. Here, it controls voice communication connections for air traffic control.
Example Sentence 1
The controller used the Voice Switching and Control System to switch from the pilot's frequency to a landline call with the next sector.
Example Sentence 2
During peak traffic, the Voice Switching And Control System allowed seamless handoffs between multiple controllers on different channels.
