The Digital Air Data Computer AC32 measures barometric altitude and airspeed using vibrating cylinder pressure sensors for both static and pitot ports.
These sensors are highly accurate and stable making the 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.
With flexible configurability the AC32 computer is capable of supplying altitude pre-select, baro correction, MACH number, discrete word output and more to next generation equipment with minimum alteration to the aircraft’s system architecture.
The AC32 meets the requirements for multiple platforms and can be interfaced with TAWS, ACAS/TCAS, EGPWS, FMS systems, and ADS-B transponders.
By pressing the optional scale button, the measurement units can be switched between meter and feet and the barometric setting between mbar/hPa and InHg.
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 and light weight make the THOMMEN AC32 a preferred choice for aircraft modernization and upgrade programs.
