摘要：	The fuel-efficiencies of arrival flights that were managed by an automated system werecompared to the fuel-efficiencies of arrival flights that were managed by air traffic controllers.It was infeasible to have the automated system control arrivals in real operations, so thecomparison was accomplished by setting up a fast-time simulation where the automatedsystem could manage arrivals with the same initial conditions and flight plans as those thatoperated in real operations during a selected comparison period and in the same backgroundtraffic. For this study, Newark Liberty International Airport was selected as the arrivalairport because its high traffic load and constrained arrival procedures were expected tohighlight fuel-efficiency benefits of an automated system. In the simulation, the automatedsystem managed Newark arrivals, and the other flights (arrivals to other airports, departures,and overflights) composed the background traffic. To match the simulation and the realoperations background traffic, the other flights flew in simulation the same trajectory thatthey flew in real operations during the comparison period. Fuel-efficiency was measured bycalculating fuel burns of the arrival trajectories. The fuel-efficiencies of arrival trajectoriesproduced in the simulation were compared with the estimated fuel-efficiencies of arrivaltrajectories recorded from real operations during the comparison period. Results showed thatautomation managed arrivals burned 346 lbs less fuel per flight on average than controllermanaged arrivals.
