Operational efficiency of maneuver coordination rules for an airborne separation assurance system

To facilitate the continuing growth of air traffic and the request for more operational flexibility, users will require various systems not only to prevent collisions but also to allow on-board separation assurance without air traffic controller intervention. This responsibility shift implies that maneuver coordination between aircraft will no longer lie with one central controller but rather will be based on maneuver coordination rules typical to fully or partly decentralized systems. Clearly, higher rule complexity, assuming a proper design, leads to additional gains in safety and maneuver efficiency for particular operational environments. However higher rule complexity often requires more input information and more computation for rule application, which might have a negative impact on safety and increases system cost. This paper discusses the rule complexity / rule efficiency problem. Rule eff iciency measures are discussed and mathematically defined. Further, an approach to evaluate different rule structures for an airborne separation environment using computerbased models is described and results are presented.
