== Abstract ==&lt;br /&gt;
&lt;br /&gt;
To support the need for increased flexibility and capacity in the future National Airspace System, NASA is pursuing an approach that distributes air traffic separation and management tasks to both airborne and ground-based systems. Details of the distributed operations and the benefits and technical challenges of such a system are discussed. Technology requirements and research issues are outlined, and NASA''s approach for establishing concept feasibility, which included development of the airborne automation necessary to support the concept, is discribed.&lt;br /&gt;
