Abstract
In a gyro horizon type of equipment, roll corrections are fed to the aircraft symbol which is a normally fixed display element and pitch correction is introduced on a movable display element or drum with modification of the position of the display elements of the instrument gyro as a function of an interconnection of the instrument gyro with a gyromaster reference through comparators connected to each of the roll and pitch systems.

Apparatus for facilitating the piloting of aircraft comprising
- a gyroscopic horizon including a vertical instrument gyroscope with a built-in erector means, and pitch and roll indicator means,
- transducer means to transmit electrical signals proportional to pitch and roll changes attached on the pitch and roll suspension axes of said vertical instrument gyroscope,
- gyroscopic reference means having stable gyroscopic means and pitch and roll electrical transducer means attached to said gyroscopic means,
- first comparator means connected to receive and compare the signals and produce a signal output proportional to the difference in signals from said pitch electrical transducer means of said gyroscopic reference means and said pitch transducer means of said vertical instrument gyroscope,
- second comparator means connected to receive and compare the signals and produce a signal output proportional to the difference in signals from said roll electrical transducer means of said gyroscopic reference means and said roll transducer means of said vertical instrument gyroscope,
- pitch and roll operating means to cause the movement of said pitch and roll indicator means in accordance with said signal outputs from said first and second comparator means.
A method of introducing and indicating pitch and roll information with an artificial horizon instrument of the type having a vertical gyroscope with a built-in erector means which comprises the steps of
- obtaining pitch and roll electrical signals from a reference or master gyroscope,
- comparing electrical signals furnished by transducers mounted on the pitch and roll suspension axes of said vertical gyroscope to said respective pitch and roll electrical signals from said reference or master gyroscope,
- applying pitch and roll angular deviation signals obtained from said comparing of signals to pitch and roll indications displayed by said instrument.
