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 ofresearch carried out in the Gromov flightResearch Institute (GFRI). In-flight experimentsare conducted on Ilushin-103 aircraft todetermine pilot sensitivity thresholds to angularand linear motion in order to clarify andcomplete the database available. Specialattention is paid to the effect of normal G-loadon the angular motion perception. The paperdescribes experimental procedure which is thefactor determining effectiveness andcompleteness of the in-flight results. The resultsreceived confirmed and broaden out the data onthe sensitivity thresholds, in particular on theeffect of normal accelerations on the perceptionof aircraft angular motion.
