Order purpose statement

TBFM is a computerized decision support tool for Air Traffic Controllers (ATC).  TBFM is a time-based metering automation tool. TBFM provides benefits throughout the NAS, maximizing the use of available NAS resources, minimizing delays and disruptions to aircraft operators and their customers, as well as reducing fuel burn and engine emissions from reduced delays.

The TBFM system's mission is to utilize the available airport capacity efficiently without decreasing safety or increasing controller workload.  The end users of TBFM are Traffic Management Coordinators (TMC) and controllers in ARTCCs, and TMCs in Terminal Radar Approach Controls (TRACON) and towers.  The TMCs interact directly with the TBFM via display and input devices added into the Traffic Management Unit (TMU).  The controllers interact indirectly with TBFM via the user interface on the En Route or terminal Air Traffic Control (ATC) automation systems.
