This citation summarizes a one-page announcement of technology available for utilization. A new flight-management descent algorithm designed to increase fuel savings has been flight tested. The algorithm reduces the time dispersion of airplanes crossing the metering fix. A three-dimensional path with terminal time constraints (four-dimensional) is determined by the algorithm for an airplane to make an idle-thrust, clean-configured descent to arrive at the metering fix at a predetermined time, altitude, and airpeed. ...FOR ADDITIONAL INFORMATION: Detailed information about the technology described may be obtained by ordering the NTIS report, order number: NASA-TP-1717, price code: A03.
