Airbus 320 AND 737NG Performance Differences in advanced RNP to XLS Arrivals.

Kurzfassung

We report on the performance comparison between an Airbus A320 and a Boeing 737NG in vertical path following and speed profile during novel advanced required navigation performance (RNP) procedures which contain a fixed radius turn that delivers the aircraft onto a short ILS precision final. The approaches were flown automatically with guidance and automatic thrust as computed by the flight management system. Main areas of interest of the flight trials were the performance of the vertical path following during the RNP part of the procedure as well as maintaining an optimized speed profile during the continuous descent approaches.
