Digital Air Data Display AD32
Available from THOMMEN AIRCRAFT EQUIPMENT Ltd.
The AD32 combines an air data computer with a digital altimeter in a 3ATI form factor. This makes the AD32 ideally suited for replacing standby altimeters in fixed wing & rotorcraft while minimizing installation efforts.
The AD32 measures pitot and static pressure using Vibrating Cylinder Technology (VCT) sensors. These sensors are highly accurate and stable making our AD32 virtually drift-free, effectively eliminating calibration and exceeding FAA Technical Standard Order (TSO) accuracy requirements.
The AD32 can be equipped for RVSM and/or NVIS compatibility to suit aircraft system requirements. Additional options allow the pilot to switch between metric and imperial altitude information.
The AD32 communicates via its ARINC429 interface. Data in-/output can be configured per requirements.
With flexible configurability the AD32 is capable of supplying altitude pre-select, baro correction, discrete word output with minimum alteration to the aircraft’s system architecture.
THOMMEN’s AD32 meets the requirements for multiple platforms and works in conjunction TAWS, ACAS/TCAS, EGPWS, FMS systems, and ADS-B transponders. This unique air data computer & altimeter unit is suitable for most aircraft modernization and upgrade programs. Up to 2 x 16 SSEC curves are possible.
The AD32 is also available as ARINC408 form fit. ICAO encoded altitude output, AOA sensor input, and an RVSM version are optionally available as well as a variety of pneumatic adapters and installation kits.
