An artificial, or gyro, horizon is the main instrument pilots use to fly through bad weather and low-visibility conditions. It indicates the aircraft's orientation relative to the earth, expressed as pitch, roll, and yaw. This is the first production model, the same type Doolittle used in his historic 1929 "blind flying" test.
