Digital Encoding Altimeter AD32 DEA80

The THOMMEN Digital Encoding Altimeter AD32 DEA80 with extended altitude range, suits every aircraft category including those reaching altitudes above the usual air traffic.

Technically based on the rugged AD32 air data unit design, this DO-178B Level A certified altimeter system exceeds any TSO C10b accuracy requirements throughout the entire altitude range up to 80’400 ft / 24.500 m.

Available in two case designs and with different lighting options including optional MIL-STD3009 NVIS green A/B compliance, it easily replaces obsolete mechanical altimeters.

No-maintenance required. The integrated high-end VCT sensor makes the Digital Encoding Altimeter AD32 DEA80 free from needs for scheduled maintenance or re-calibration.

Together with a fast reacting stepper-motor driven pointer, this sensor type enables virtually “real-time” indication of the altitude during high-speed vertical maneuvers.

Optionally the system features an integrated altitude alerter (up to FL650) with configurable parameters, altitude pre-select, alerter light and discrete output to a warning tone generator.

The extended barometric setting range from 700…1066 mbar allows QFE operation on high-elevation airfields.

The Gillham gray code (ICAO) is provided by a parallel electrical interface for direct replacement of older encoders or encoding altimeters and is compliant to TSO C88a.

In addition the pressure altitude (label 203) and the baro corrected altitude (label 204) can be transmitted through the ARINC 429 interface.

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 RS232 maintenance interface without removing the unit from the aircraft.

The Digital Encoding Altimeter AD32 DEA80 is also available with square front bezel and 3ATI case in black or grey color.
