Distributed air/ground traffic management: results of preliminary human-in-the-loop simulation

In September 2002, NASA´s Advanced Air Transportation Technologies project office sponsored a human-in-the-loop simulation of Distributed Air/Ground Traffic Management (DAG-TM) concepts. The simulation examined three DAG-TM Concept Elements (CEs) which included: (1) CE 5 which is En Route Free Maneuvering for: (a) User-Preferred Separation Assurance; and (b) User-Preferred Local Traffic Flow Management (TFM) Conformance; (2) CE 6 which is Trajectory Negotiation for (a) User-Preferred Separation Assurance, and (b) User-Preferred local TFM Conformance; and (3) CE 11 which is terminal Area Self-Spacing for Merging and In-Trail Separation.
