Model: AHC-3000S


Collins Aerospace


Attitude Heading Ref Computer

Part Number :

AHS-3000/3000() AHRS System



  • Attitude Heading Reference Systems (AHRS)
  • AHS-3000() System is designed for ARINC 429 equipped aircraft
  • Featuring digital quartz microelectromechanical systems (MEMS) sensors that provide heading and attitude information to the flight deck and other on board systems
  • Solid-state sensor technology for high reliability
  • Up to 10,000-hour mean time between failures rating
  • Designed for both new aircraft and as replacement installations
  • Analog and synchro interface for retrofit applications
  • Primary function is to provide measurements of the aircraft pitch, roll and heading Euler angles for use by the flight deck displays, flight control systems and other avionics equipment
  • High-quality body rate, Euler rate and linear acceleration outputs are provided for enhanced flight control system performance 
  • Advanced EMI/HIRF/Lightning isolation
  • Built to withstand extreme environments involving high roll rates & vibration, designed for use in a variety of aircraft types
  • Automated compass swing
  • Uses existing five or six wire flux detector interfaces
  • Compact Design - Reduced weight, size & power requirements
  • Easier installation through new auto-leveling feature
  • Configurable outputs for interface flexibility
  • Typical AHC-3000A systems include:
    • AHC-3000A Attitude Heading Computer,
    • FDU-3000* Flux Detector Unit,
    • MMT-3010 Multi Modular Mount, and
    • ECU-3000 External Compensation Unit
  • *In AHC-3000A System - FDU-3000 is not required for aircraft that already have FDU-70() installed
  • Typical AHC-3000S systems include:
    • AHC-3000S Attitude Heading Computer,
    • 323A-2G Flux Detector Unit (& ARINC standard 3 wire),
    • MMT-3010 Multi Modular Mount, and
    • ECU-3000 External Compensation Unit
