Ride quality evaluation. IV - Models of subjective reaction to aircraft motion

Time motion histories and judgments of perceived comfort were obtained for three planes (Nord, Twin Otter, Beech) and a helicopter (S-61). Regression models were obtained predicting rated comfort from rms values for six degrees of freedom of motion. The model C  =  2.1 + 17.1 T + 17.2 V gives a good fit to the plane data, but is less acceptable for the helicopter data.
