Air Data, Attitude and Heading Reference System (ADAHRS) replaces DGVG’s, AHRS and air data computers in a single, compact, light-weight unit. Coupled with the IS&S Beta-3 GPS Receiver it can provide INS grade performance to 25 foot 3D positional accuracy. The IS&S ADAHRS outputs in Digital and Analog in format aircraft attitude, heading, altitude and air speed to interface with existing autopilot and display systems at a fraction of the cost of comparable AHRS alone. Features and Benefits: Versatile interface capability Highly accuracte air data sensors Directional Gyro Mode Software RTCA DO-178B level B Control interfaces via discretes andor ARINC 429 RVSM support GPS aiding for improved accuracy

Technical Overview The IS&S Model 9B-81103-1 Air Data Sensor (ADS) replaces the Rockwell Collins 590A- 3H3J3K3J13K1 Air Data Sensor as either a formfit function replacement unit, or as part of a more comprehensive Reduced Vertical Separation Minimum (RVSM) compatible air data system upgrade. This upgrade includes the IS&S Model 9D-80130 Air Data Display Unit (ADDU). In both configurations the ADS utilizes the same tray and aircraft mating connectors as the displaced Collins 590 unit. The ADS operates the same in both configurations, relative to the flight control system interface and operation. The ADS supplies an analog error signal to the flight control system (FCS) that is proportional to altitude HOLD error, vertical speed HOLD error, Mach HOLD error, Indicated Airspeed HOLD error, or preselect altitude error that is used by the FCS to ascend or descend to a preselected altitude. True Airspeed, Indicated Airspeed, and Altitude programming voltages are also supplied to the flight control system. Reliability and Maintainability Long-term supportability due to modern design. Two-year warranty. MTBF 20, 000 hours.
