Abstract:
Twenty-four hours before a scheduled flight departs, data on this flight from the Official Airline Guide (OAG) is loaded into the Enhanced Traffic Management System (ETMS). This flight is then included in the Monitor/Alert demand predictions that ETMS makes and presents to traffic managers. Since the OAG does not provide the route of flight, ETMS's trajectory model uses a default route, which currently it generates by using the route that this flight has recently flown most frequently. These ETMS historical, default routes, which are used until the flight plan has been received, have been criticized as inaccurate, especially for flights longer than two hours. Since this inaccuracy degrades the predictions of sector loading, this is seen as a serious problem.
