Commercial and military aircraft utilize proven data bus standards such as MIL-STD-1553B and ARINC 429. However, future avionics systems may take greater advantage of commercial hardware and networking technology. With the increased processors and speeds, it is possible to begin challenge the fundamental avionics architectures used for navigation and flight control. This is particularly true for UAVs, where there is currently rapid change. Goals of new architectures include reduced development time, cost; increased testability; lead to quicker flight validation, and higher integrality. Of these, the concepts addressed in a new architecture include scheduling tasks and continuous integration.
