SECTION II
General Information
This Section provides the description required to understand the functionality of AC32 Digital Air Data
Computer equipment. Refer to the following paragraph for the brief description of the instrument.
Description
A. Equipment Description
The AC32 Digital Air Data Computer belongs to the Solid State Flight equipment Family of REVUE
THOMMEN AG. The implementation of the AC32 Digital Air Data Computer measures barometric
altitude, airspeed and temperature in the atmosphere. It has integrated solid-state pressure sensors
for static and pitot pressure. The AC32 is RVSM compliant and provides up to 2 x 16 SSEC curves.
This specification covers a Digital Air Data Computer with
- Primary Altitude computation
- Airspeed and MACH computation
- ARINC429 Interface
- Encoded altitude output (optional)
- TAT probe input (optional)
The computed air data parameters are transmitted by the ARINC 429 serial data bus interface. Two
transmit channels and two receive channels are available, with which also the baro correction is
carried out. An ICAO encoded altitude output is also available as an option.
The AC32 is designed modular and hence very easy to maintain by RS-232 maintenance interface
serial data. Its power supply is available for 28 VDC. The low power consumption of less than 7 Watts
and its low weight of only 1000 grams (2.2 lbs) have been optimized for applications in state-of-the-art
avionics.
The THOMMEN AC32 Digital Air Data Computer can be configured for different applications as per
the interface requirements. Therefore its application range reaches from Business Aviation up to
Regional Aircraft, Transporters and Helicopters.
The THOMMEN AC32 Digital Air Data Computer meets or exceeds the requirements of the FAA
technical standard order TSO-C106 and TSO-C88a accuracy requirements.
The AC32 Digital Air Data Computer communicates with flight Displays that show the data of the
AC32 Digital Air Data Computer and allows the Baro correction. The communication uses the ARINC
429 serial data bus.
This AC32 Digital ADC does not support the analog interfaces.

Revision 2.1
Operations
Caution:
The AC32 Digital Air Data Computer equipment has been designed to exhibit a very high
degree of functional integrity. However it is possible that erroneous operation could occur
without fault. It is the responsibility of the operator to detect such an occurrence by means of
cross check with redundant or correlated information available in the cockpit.
A. Theory of Operations
This part of the manual is to familiarize the reader with the AC32 Digital Air Data Computer
equipment and to give a brief theory of operation.
A.1 Power Supply
The AC32 Digital Air Data Computer is designed to be supplied by a 28 VDC power supply in
accordance with RTCA/DO-160D Section 16.0 Category Z.The equipment does not require more
than 7 W for normal operation.
An optional secondary 28 VDC emergency power supply input, drawn from emergency bus should be
provided to continue operation, in case of primary power supply failure.
NOTE: In case of power fail or switching off the equipment‟s power supply the AC32 sets the
warning flag valid output signal to LO (WFVOUTS).
A.2 Micro Controller
The Micro Controller is a flash type micro controller built around CPU (Central Processing Unit) board
of the instrument. The CPU has an internal 32-bit architecture which is provided with sixteen 16-bit
general registers and a concise, optimised instruction is designed for high-speed operation. The CPU
can also address a 16-Mbyte linear address space.
The operating voltage and the port power voltage of the Micro controller is +3.3 VDC. A crystal
oscillator of 4 MHz is connected to the micro controller and an internal clock generator produces the
system clock of 16 MHz.
The data and address bus from the Micro controller is also used for the two functions used outside
the CPU. This is for the communication with both the ARINC 429 and to the latches for the ICAO
encoded output of the instrument.

A.3 ARINC 429 Interface
The ARINC 429 module in AC32 Digital Air Data Computer supports the ARINC-I/O interface and the
bus interface to the CPU.
The ARINC 429 offers the following main features:
-Two transmitter and two receiver ports
-ARINC Low-Rate & High-Rate support with appropriate slew-rate control
-Multiple local loop-back facilities for improved BIT
-Lightning Induced Transients Suppression compliant with RTCA/DO-160D
-Hardening against aircraft wiring errors on ARINC inputs
Digital Data Standards are acc. to ARINC 429 Mark 33 DITS and ARINC 706-4 Mark 5 SADS /

purposes only. This interface is not accessible for normal operation in the aircraft.
The RS-232 Interface is provided for calibration and maintenance causes has the following
transmission parameters:
Baud Rate...…... 9600 kBit/s
Start Bits...…..... 1
Data Bits....……. 8
Stop Bits.....…... 1
Parity...........…... None
A.5 Configuration Identification
The configuration identification defines a specific equipment configuration parameterized by the
individual parameter lists for each AC32 equipment, which in turn explains the different parameter
requested by the installer. So for every new AC32 equipment different Configuration ID number is
designated.
CONFIGURATION ID 5001 (SAMPLE)
NOTE: Refer to Technical Checklist for Configuration ID (Identification) designation.
