AoC number


Primary domain



Integration of aircraft systems and controls will provide unprecedented utilization of automation, communication, navigation and surveillance accuracy and integrity. Advanced automation is taking full advantage of data sharing among previously independent components and systems. As more crew functions are automated there is a high reliance on the integrity and fidelity of the data exchanged.

Potential hazard

  1. High and low criticality functions sharing computing and data bus resources instead of being physically separated. Software-based isolation and independence is much more “fluid” and difficult to assure than relying on hardware.
  2. Lost or erroneous inputs can result in a cascade of effects on the aircraft.
  3. Inadequate self-checks to verify software for accuracy and integrity due to system complexity.
