Sigma-Tek 5000B Series Attitude Indicators (Artificial Horizons) are air-driven gyros that have a pictorial horizon mask and fixed airplane. The mask moves to indicate climb, dive, and bank. Bank and pitch attitudes are displayed so that the pilot’s sensing of the gyro indication is the same as the interpretation of the relation between the wings of the aircraft and the natural horizon during visual flight. These instruments are FAA certified (TSO-C4c), and can be used to replace the aircraft’s turn coordinator when equipped with an inclinometer. Different versions available mainly based on the layout, dispay colors, warning flag and lighting capabilities. Lighted indicators do not include lamp trays which are sold separately based on the aircraft voltage (14V or 28V).
