The 55X installation is modular, consisting of four primary components that must be interfaced correctly:
, allowing the GPS navigator to send turn-by-turn instructions directly to the autopilot, bypassing HSI wandering. Digital Displays S-tec 55x Installation Manual
: Must use shielded wire where indicated; grounding must occur only at specified points to prevent interference.
(e.g., Garmin G5, G3X, or Aspen Evolution). The manual details the specific pinouts for ARINC 429 or analog heading/course datum connections. The manual details the specific pinouts for ARINC
The S-TEC System 55X is one of the most reliable and widely installed aftermarket autopilots in General Aviation (GA). Navigating its installation requires strict adherence to Federal Aviation Administration (FAA) regulations, precise mechanical calibration, and meticulous electrical wiring.
A complete S-TEC 55X installation involves both panel-mounted controls and remote-mounted hardware. precise mechanical calibration
Wire an Autopilot Master Switch (AP DISC) directly to the pilot's yoke. This must interrupt power to the servo clutches instantly when pressed.
Installing the is a complex procedure that must be performed by authorized S-TEC dealers or technicians with appropriate FAA certification. This draft guide outlines the core components, wiring standards, and checkout procedures typically found in the installation manual. 1. System Components & Layout
The System 55X requires a connection to the aircraft’s static system for altitude functions.
