S-TEC Altitude Transducer Assembly

This part number designates a remote-mounted, solid-state barometric sensor manufactured by S-TEC Corporation. It functions as a critical subsystem component designed to provide real-time pressure altitude data directly to the autopilot’s pitch flight guidance computer. It is universally deployed across the majority of S-TEC autopilot installations, including the S-TEC System 30, 50, 55, 55X, and 60-2 configurations.

Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 06/03/2026.

Key Technical Capabilities
  • Altitude Hold Stabilization: Continuously measures absolute static pressure deviations to detect micro-changes in aircraft altitude. It converts these pneumatic pressure variations into electronic feedback loops to allow the autopilot pitch computer to execute steady altitude hold functions. 
  • Pitot-Static System Integration: Designed to inline “T-fitting” splice directly into the aircraft’s primary static pressure tubing array, plumbing it parallel to the primary altimeter and altitude reporting encoder. 
  • Dynamic Pitch Correction: Translates instantaneous barometric altitude changes into vertical command errors, prompting the automated flight guidance loop to trim the elevator pitch servo appropriately during turbulence or environmental updrafts/downdrafts.
  • Solid-State Reliability: Engineered without mechanical moving diaphragms or standard internal glass components, minimizing electrical drift and protecting the sensor calibration against severe engine vibrations and airframe shock loads.
