Core aerospace engineering and protocols for ARINC 653 Partitioning.
Federated avionics assigned a separate physical box (LRU) to every function—one for autopilot, one for fuel management, one for flight displays—resulting in massive aircraft weight. Integrated Modular Avionics consolidates multiple applications onto shared compute nodes.
AvionicsNodes implements ARINC 653 robust partitioning: each application executes within an isolated virtual partition with hard-scheduled CPU windows and physically locked memory pages. Even if a passenger entertainment app crashes into an infinite loop, the DAL A fly-by-wire partition continues executing uninterrupted.
