Overview
The S-TEC 55X Installation Manual is the definitive technical reference for certified avionics installers and maintenance personnel responsible for integrating the S-TEC 55X two-axis autopilot into general aviation aircraft. Originally developed by S-TEC and now supported by Genesys Aerosystems, this manual provides comprehensive, FAA-acceptable data for the physical and electrical installation of one of the most popular rate-based autopilots in the industry. connected to the aircraft’s control cables.
- System malfunction: Troubleshooting guides for common system errors and faults.
- Servo issues: Troubleshooting guides for servo problems, such as binding or failure.
- Sensor calibration: Procedures for recalibrating sensors and ensuring proper system performance.
Once the hardware is in, the manual guides the technician through a series of "bench tests" while the aircraft is still on the ground:

- The manual provides instructions for connecting NAV deviation signals (typically 150mV full-scale deflection).
- Reverse Sensing: A critical wiring step involves ensuring the autopilot corrects in the right direction. If wired backward, a deviation to the left will cause the autopilot to turn further left rather than right to intercept. This is tested during the ground functional check.
Servos (Roll and Pitch): The mechanical muscles of the system, connected to the aircraft’s control cables.
