Abstract: A G-force acceleration measuring instrument for use in an aircraft, spacecraft, submarine, or other vehicle, and employing electronic sensing and display transducers for increased reliability, small size, and small mass. The instrument includes a bar graph display, preferably incorporating liquid crystal transducer elements, uses a solid state or limited motion acceleration transducer, and provides graphic and numeric indication of the present G-force value together with numeric indication of historic maximum and minimum G-force values. The instrument also includes gain adjustment arrangements for accommodating different instrument panel slopes mounting in different types of vehicles with different G force capability, and a signal output tap for recording or slave indicating or telemetry or feedback use.
