The primary focus of this study was to examine the feasibility of airborne separation assurance for free flight by evaluating the performance of aircraft-based Conflict Detection and Resolution (CDR) schemes in a simulated air traffic environment using the Future ATM Concepts Evaluation Tool (FACET). Using a horizontal-plane free flight traffic scenario constructed with initial conditions from actual air traffic data, close to one thousand aircraft were modeled in a six hour scenario. Results from the performance evaluation reveal that airborne separation assurance performed effectively in the free flight evaluations in that: 1) all conflicts were resolved; 2) the impact on flight efficiency, as measured by path-length and flight- time changes, was small; and, 3) the impact on system stability was modest. The paper gives an overview of the two CDR methods used in the study, the construction of the free flight traffic scenario, and performance metrics and results for the two airborne self-separation methods.
