1. Flight instrument apparatus for use by an aircraft pilot comprising the combination of:

  • an acceleration G force to electrical signal transducer element;

    a pilot viewable length organized analog graphic display capable of aircraft instrument panel mounting and including a plurality of electrical-to-optical transducer element graph segments located in a predetermined lengthwise expansible geometric arrangement in the face thereof;

    said G force transducer element and said analog graphic display being each responsive to G-force signals in the positive and negative force directions;

    electrical circuit means for exciting said display transducer element segments in lengthwise cumulative magnitude responsive incremental order in response to said acceleration G force electrical signal;

    said G force to electrical signal transducer element, said display and said electrical circuit means being mounted within a single instrument housing and including adjustable gain control means capable of compensating off-axis mounting of said instrument in an aircraft instrument panel;

    said gain control means including a plurality of gain determining resistance elements and means connected with said resistance elements for selecting different of said resistance elements in response to said instrument being mounted in different aircraft.
