IMPORTANT FACTORS

  • Deterministic behavior
  • Fault tolerance
  • Redundancy

The key attribute required in Avionics Communications is ‘flexibility’ – both the flexibility to transition from the lab to the embedded world, and the flexibility to simulate and test a wide range of bus configurations with a single interface.

COMMERCIAL AVIONICS DATABUSES

  • ARINC-429 primary digital data bus over most of the Application layer – used virtually on all Commercial aircraft
  • ARINC-708 specific to Airborne Weather Radar systems
  • ARINC-717 Digital Expandable Flight Data Acquisition and Recording System (DEFDARS) supercedes ARINC-573, also used for Flight Data Recorders; however, adds a number of different bit rates and frame sizes
  • ARINC-419 Catalog and Compares older Avionics databus standards
    • ARINC-573 Aircraft Integrated Data Systems (AIDS) – used for Flight Data Recorders, that used 12bit words sent in a continuous data stream
    • ARINC-575 Digital Air Data Systems (DADS)
    • ARINC-585 Electronic Chronometer System (ECS)
