Abstract
For Summer 2000, the Federal Aviation Administration introduced a new collaborative procedure for reducing departure delays during weather events. This initiative involved the used of predefined Coded Departure Routes (CDRs). Goals of this procedure included:
Providing airline operations centers and FAA air traffic facilities with a process for working collaboratively to develop earlier plans for dealing with predicted constraints. Giving airport control towers greater flexibility to respond to the often rapidly changing picture regarding available airspace during weather events. Keeping airline dispatchers in the loop through the early identification of alternative departure routes to expedite departures from an airport.
An analysis of the use of CDRs was completed, based on interviews with staff at six airlines and four enroute air traffic control Centers, on analyses of System Command Center advisories and on analyses comparing filed with flown routes. Based on this analysis, recommendations are made for the design of improved tools for information dissemination and decision support.
