Next-generation aircraft architectures combine flight controls (DAL A) with passenger connectivity (DAL E) on the same platform. Here is how robust operating system partitioning guarantees zero contamination.
If a non-critical DAL E in-flight entertainment container attempts a denial-of-service attack or enters an infinite loop, AvionicsOS hardware MMU fences clamp its execution within its allocated time budget, allowing DAL A flight guidance to run without disturbance.
Rigorous stress testing demonstrates that DAL E faults generate zero measurable latency degradation on primary flight displays, fulfilling all regulatory requirements for mixed-criticality airborne deployment.
