A seat cushion to provide acceleration cues for aircraft simulator pilots has been built, performance tested, and evaluated in NASA Langley's Differential Maneuvering Simulator. The four-cell seat, using a thin air cushion with highly responsive pressure control, attempts to reproduce the same events which occur in an aircraft seat under acceleration loading. The pressure controller provides seat cushion responses which are considered adequate for current high-performance aircraft simulations.
An experiment was designed to evaluate the effect of the g-seat on pilot/simulator performance. The statistical analysis of data indicates that the pilot gets information from the seat which allows more precise control of the simulated aircraft. Pilot subjective data support the conclusions of the statistical analysis.
