SIMULATION STUDY OF THE EFFECT OF FUEL-CONSERVATIVE APPROACHES ON ATC PROCEDURES AND TERMINAL AREA CAPACITY

Two simulation experiments were conducted to investigate fuel-conservative approaches in an ATC environment. The first experiment centered on delayed flap and IATA approaches and how they could be mixed with conventional approaches under various traffic levels. The second experiment investigated the fuel savings potential of profile descents. The IATA approach appears to offer a good compromise between fuel efficiency and capacity in a mixed environment. While it saves about one half to two-thirds of the delayed flap approach fuel, it has less impact on capacity and controller workload in the 35 aircraft/hr traffic situation. The second experiment revealed that the profile descent procedures would result in at least a 10% average fuel savings during descent. In addition, since fewer radar vectors were required for profiles, the profiles showed a significant reduction in controller workload with respect to conventional aircraft.
