This study provided a preliminary investigation of the benefits of increased pilot involvement in two representative air traffic management operations: maintaining in-trail separation and arrival sequencing. Airline pilots flew arrival routes in a part-task, medium fidelity simulator while performing these operations. A variety of traffic displays and procedures were tested, and the pilots' performance was tracked during both nominal and offnominal traffic situations. Results provide preliminary evidence of the benefit of these operations. Suggested modifications to traffic displays are given. The need for established air traffic control procedures to provide fore-knowledge to the pilots and a structure for pilots within which pilots can interact is also highlighted.
