Simulation of visual blackout due to aircraft maneuvering

摘要

A means of simulating loss of peripheral vision and the eventual total black-out experienced by a pilot, undergoing high acceleration forces while maneuvering an aircraft is disclosed. The simulation is achieved by modifying the pilot's helmet by incorporating thereon a variable optical device which when excited causes a reduction of pilot vision. The reduction in vision is progressive, in direct proportion to the level of excitation applied, which excitation itself is directly proportional to the acceleration forces simulated.
