Digital Air Data Computer AC32

The AC32 Digital Air Data Computer measures barometric altitude and airspeed using vibrating cylinder pressure sensors for both static and pitot ports.

These sensors are highly accurate and stable making our AC32 virtually drift-free, effectively eliminating calibration and exceeding FAA Technical Standard Order (TSO) accuracy requirements.

The AC32 Digital Air Data Computer communicates via ARINC429 interface. Data in-/output can be configured per specific aircraft requirements keeping non-recurrent costs at a minimum.

The AC32 meets the requirements for multiple platforms and can be interfaced with TAWS, ACAS/TCAS, EGPWS, FMS systems, and ADS-B transponders.

Continuous Built-in-Test (BIT) software secures safe operation; the BIT-failure memory can be read out via the easy access RS232 maintenance interface without removing the unit from the aircraft.

Comprehensive configurability, low maintenance effort, light weight, and affordable pricing make the THOMMEN AC32 a preferred choice for aircraft modernization and upgrade programs.

 

Optional versions available:

ICAO encoded altitude output, AOA sensor input, RVSM tolerances, and supersonic versions are optionally available.

AC32 Product Configurator Software

AC32_Configurator_Setup (81.20 MB)
This software tool is available for Windows 11, Windows 10 and Windows 7. It requires MS Office and a native PDF reader such as Adobe Acrobat Reader.

Welcome to the THOMMEN AC32 Configurator.

Configure the AC32 Air Data Computer for your application with our interactive software tool “AC32_Configurator”.

 

Features of the software include:

  • Configuration of aircraft specific parameters (altitude, airspeed, and Mach range)
  • Configuration of discretes for certain functions (e.g., airspeed warnings, warning flags)
  • Individual selection of ARINC 429 labels
  • Sensor adaptation and calibration for TAT / OAT probes
  • Sensor adaptation and calibration of AoA probe
  • Specific corrections, such as SSEC, IAS offset slope or IAS/CAS conversion, can be configured
  • Internal digital filters for outputs can be configured

 

Please download the program, create a new file, complete and release your configuration and send your configuration file to our Technical Support at tech-support@thommen.aero.

Our Technical Support will reply to you as soon as possible.
