Description
The Meggitt Avionics / S-TEC Flight Line Service Manual for Rate-Based Autopilots is a factory-issued technical manual designed to support flight-line troubleshooting, testing, and verification of installed S-TEC autopilot systems.
Unlike bench-level repair manuals, this document focuses on on-aircraft functional testing, adjustment, and isolation of faults using approved S-TEC test equipment. It is widely used by avionics shops, A&P technicians, and aircraft maintenance organizations to confirm correct autopilot operation before returning an aircraft to service.
