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.
