Sigma-Tek 5000M

The 5000M is an air-driven gyro that has 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.

The instrument is provided with a caging system which is functional through 360° of roll and 90° of pitch. When caging is engaged, pitch and roll indices are aligned within two degrees.

This instrument is FAA certified, and can be used to replace the aircraft’s turn coordinator when equipped with an inclinometer.
