S-Tec System 50
Description
The SYSTEM 50 Autopilot provides all of the features of System 40, but with the additional feature of altitude hold. The system Programmer/Annunciator/Computer unit utilizes the same roll axis circuitry as System 40, plus an accelerometer for short-term pitch axis stabilization, and automatic interruption of altitude hold in severe turbulence. Pitch axis signal inputs are derived from a reliable solid state absolute pressure transducer and the accelerometer, not the artificial horizon gyro. This provides precise, instantaneous altitude and pitch control data and is independent of the aircraft vacuum system.
SYSTEM 50 consists of the Programmer/Computer, Turn Coordinator, Roll and Pitch Servos, and Absolute Pressure Transducer. Includes mounting hardware and harness. Optional Directional Gyro priced separately. System 50 is available for 13.75 or 27.5 Vdc operation. FAA TSO approved.
