Definition
An air traffic management tool that presents a real-time graphical view of aircraft positions, flight paths, and traffic flow across a region of airspace. It is used primarily by traffic management personnel to monitor demand, identify congestion, and plan flow control measures such as ground stops, reroutes, or miles-in-trail restrictions.
Plain English
A live screen that shows where all the airplanes are flying in a large area, used by traffic managers to spot crowding and decide how to keep the system moving smoothly.
Context Anchor
Seen on panel-mounted or portable cockpit displays that present nearby aircraft traffic information.
Why Pilots Care
It supports real-time traffic monitoring to reduce the risk of conflicts and maintain safe separation from other aircraft.
Intuition Check
Traffic here means other aircraft, not road traffic. A TSD shows traffic information; it does not guarantee that every aircraft nearby will appear on the screen.
Example Sentence 1
The traffic management coordinator watched the TSD and saw a buildup of arrivals into the New York area, prompting a miles-in-trail restriction.
Example Sentence 2
With the TSD active, the pilot quickly spotted the converging aircraft on the display.
