In-Flight Handling Qualities Investigation of Airbus a 310 Dlc. Configurations on Landing Approach Using the Dfvlr-Hfb 320 Variable Stability Aircraft

摘要

In-flight simulation of the longitudinal and lateral/directional dynamics of the Airbus A 310 aircraft using the DFVLR-HFB 320 variable stability aircraft was studied. The evaluation of different spoiler direct lift controls (DLC) concepts for longitudinal control was stressed. The influence of these concepts handling qualities and pilot-vehicle performance under real instrument landing systems (ILS) approach environmental conditions was determined. Sixty-three ILS approaches were flown by two pilots evaluating four aircraft/DLC configurations. The main handling quality parameter for DLC enhanced longitudinal control is the flight path to pitch attitude phase. A new general applicable flight path to pitch attitude phase criteria is proposed.
