Air Data Inertial Reference System

Air Data Inertial Reference System (ADIRS)

Our third-generation air data inertial reference system with digital gyros provides high system reliability and performance with reduced operation and maintenance in a 4 modular concept unit package.

Our third-generation air data inertial reference system with digital gyros provides high system reliability and performance with reduced operation and maintenance in a 4 modular concept unit package.

It is interchangeable with earlier 4 modular concept unit (MCU) air data inertial reference system (ADIRS) and 10 MCU ADIRS (with a tray adapter).

Other key product highlights are:

  • Automatic re-alignment eliminates the requirement to manually select down-mode align between flights or while waiting for dispatch
  • Automatic gyro accelerometer calibration lowers maintenance costs
  • Simplified sensor replacement allows for the repair of individual sensors without recalibration
  • High latitude magnetic map, 82.5 degrees
  • Shortened alignment times (typically 5 to 7 minutes)
  • Enhanced built in test equipment (BITE) provides performance monitoring and predictive maintenance messages
  • Digital gyro with self-contained electronics improves performance and simplifies air data inertial reference unit repair
  • Current gyro fleet reliability exceeds 250,000 mean time between failures
