All About TMU
It is the job of TMU to balance air traffic demand with system capacity to ensure maximum efficiency and utilization of the airspace. As a result, this creates a safe and orderly flow of traffic while minimizing delays. TMU reports to the ATCSCC (Air Traffic Control System command center).
Some of the methods that can be used to help minimize delays are the following:
Altitude
Minutes-in-trail/Miles-in-trail
Fix balancing
Airborne Holding
Sequencing programs which include Departure sequencing program (DSP), Arrival Sequencing Program (ASP)or En-route sequencing program (ESP).
Ground Delay Programs
Ground Stops.
