Trajectory management concept ATC GLOBAL Amsterdam, March 7, 2012

Presented by Gabriele Zaki, DFS Christian Bousmanne, Eurocontrol

WP B

 4D Trajectory, the cornerstone of SESAR  Its evolution through the life cycle  Prioritising the arrival time in planning  Allocation of CTA/CTO during flight.  Evolution towards Trajectory Based Operations

4D Trajectory; the Cornerstone of SESAR  Systematic sharing and synchronization between aircraft & ground of the 4D trajectory, including its prediction  Planning, agreement, update and revision of the trajectory (through CDM)  Increased automation and enhanced data interoperability with new technologies  Improved metering and sequencing of flights, based on accurate information.
