ABSTRACT: The ride motions of a Maglev system were simulated by performing specific vertical and roll maneuvers in a small executive jet aircraft. After each maneuver the passenger subjects recorded a comfort rating on a 7-point scale from very comfortable to very uncomfortable. The vertical accelerations of the jet were measured with an accelerometer and recorded in a computer data file. The results showed that passenger discomfort increased with bank angle and roll rate in the case of roll maneuvers and with the magnitude of the vertical g forces in the case of vertical maneuvers.
