Air Data Computer

Features: RVSM capable Altimeter, Airspeed and Outside Air Temperature Cabin Pressure monitoring Quad fuel flowmeter monitoring capability Designed to TSO-C106 and DO160E RS232 and ARINC429 serial outputs Secondary differential pressure ports for AOA

Description:

The ADC is designed to provide air data information to a primary flight display computer. In addition to air data information, the ADC also provides information about fuel consumption and status of 3 digital inputs.

The ADC provides the following information:

• Primary Pressure Altitude
• Secondary Pressure Altitude (cabin altitude)
• Primary VSI
• Secondary VSI
• Outside Air Temperature
• Airspeed
• Secondary Differential Pressure (AOA sensor)
• Fuel information (fuel consumed and fuel flow)
• Status of digital inputs
• Primary altitude in 10 bit Mode C gray code

In order to measure the above parameters, the ADC requires the following connections:

• Aircraft’s primary static system
• Aircraft’s primary pitot system
• Cabin pressure
• Secondary static system (or top of wing pressure port)
• Secondary pitot system (or bottom of wing pressure port)
• Power
• Outside Air Temperature (OAT) probes.
• Fuel flow transponders
• Appropriate connections for the digital inputs

The ADC provides its outputs on four serial buses and one digital port:

• Primary serial port for primary flight display computer
• Secondary serial port for devices like moderns transponders and GPS units
• Proprietary serial bus for future devices like display heads and autopilot interfaces
• AIRINC429 output for AIRINC429 capable devices
• Primary altitude in 10 bit Mode C gray code for legacy transponders
