Increasing the margins — More freedom in trajectory based operations
Alexander Kuenz · 2014 IEEE/AIAA 33rd Digital Avionics Systems Conference (DASC) · 2014
— Conflict-free scenarios always predictable — Lateral resolution rarely used — Necessary changes small — Mainly used “time shift”, no degradation of efficiency — Up to 3.5 NM freedom in every direction — Up to 23s freedom along track — 4DCo-GC proved that margins are reasonable for simulations
