ABSTRACT:
A seat cushion for providing realistic acceleration cues to an aircraft simulator pilot. A plurality of contiguous seat cushion compartments with each including an air cell with a non-compressible surface underneath the air cell are provided with apparatus for separately controlling the pressure in the air cells. Apparatus are provided for initially controlling the air pressure in the air cells to allow the two main support areas, the tuberosities, of the simulator pilot to touch the non-compressible surface and thus begin to compress the flesh near these areas. Thereafter during a simulated flight apparatus are provided for controlling the air pressure in the cells to simulate the events that occur in a seat cushion during actual flight.
