Trajectory-based operations study team 2010 ICNS

In air traffic management system every aircraft that is operating in or managed by the system is represented by a four-dimensional trajectory (4DT). It is either provided by the user or derived from a flight plan or type of operation. Trajectory-based Operations (TBO) provides separation, sequencing, merging and spacing of flights based on a combination of their current and future positions. TBO operates gate-to-gate, extending benefits to all phases of flight operations. TBO uses the 4DT to both strategically manage and tactically control surface and airborne operations.
