SIGMA-TEK VACUUM ATTITUDE INDICATOR 5000E-13

Sigma-Tek Vacuum Attitude Indicator 5000E-13. The Sigma Tek 5000E-13 air-driven attitude gyro 1U149-010 is another variation of our standard 5000B model. The Sigma-Tek Vacuum Attitude Indicator 5000E-13 includes inductive pick-offs that generate the signals necessary to drive an autopilot. The intuitive display has a moving horizon mask that indicates the position of the aircraft’s wings in relation to the natural horizon. This attitude information is passed along to the autopilot system. This is one of the most popular primary instruments. It is FAA approved, and can replace the turn coordinator when equipped with an inclinometer.
