Conclusions from the document:
Trajectory-oriented, time-based arrival operations have shown potential benefits for throughput, efficiency, and controller workload. In order to achieve these benefits a well-designed set of ground automation tools and procedures is required. The operational concept described in this paper and similar approaches provide the necessary flexibility for being applied in high-density air traffic control sectors. The trajectory-oriented approach can be complimented with aircraft-to-aircraft based operations to increase the potential benefits even further while at the same time solving some of the problems with 4D trajectory-based operations.
