REFINEMENT OF THE MODEL OF PILOT PERCEPTION OF AIRCRAFT MOTION IN UPSET CONDITIONS UTILIZING FLIGHT TESTS RESULTS

摘要

Presented in the paper are the results of research carried out in the Gromov flight Research Institute (GFRI). In-flight experiments are conducted on Ilushin-103 aircraft to determine pilot sensitivity thresholds to angular and linear motion in order to clarify and complete the database available. Special attention is paid to the effect of normal G-load on the angular motion perception. The paper describes experimental procedure which is the factor determining effectiveness and completeness of the in-flight results. The results received confirmed and broaden out the data on the sensitivity thresholds, in particular on the effect of normal accelerations on the perception of aircraft angular motion.
