09 - Air Transport System EfficiencyPERFORMANCE COMPARISON OF A320 AND 737NG REGARDING THE VERTICAL AND AND SPEED PROFILES IN ADVANCED RNP TO XLS ARRIVALST. Dautermann¹, T. Ludwig¹, L. Altenscheidt¹, M. Altenscheidt, NavArt, Germany; R. Geister¹, M. Braschczok¹; ¹DLR, Germany Comparison of experimental data from an Airbus A320 and a Boeing 737NG in vertical path following and speed profile during novel advanced RNP to ILS procedures. The approaches were flown completely automatic, with guidance/thrust as computed by the FMS. Main areas of interest of the trials were the performance of the vertical path following as well as maintaining an optimized speed profile. rn |
