ABSTRACT:
A gyroscopically stabilized artificial horizon instrument used in light aircraft mounts an earth magnetic field sensitive flux sensor on its gyroscope housing to produce a signal indicative of the direction of flight. The signal is processed and produced as a digital display of direction on the face of the instrument such that the planes relation to the artificial horizon and its direction can be observed by the pilot at the same instrument location. Provision is also made for generating signals indicative of airspeed and altitude and displaying in digital form both airspeed and altitude at the same location on the artificial horizon instrument at which direction is displayed.
