Formal Methods and Run-Time Assurance for Neural Networks in Certified Airborne Systems

Core aerospace engineering and protocols for DO-178C DAL A AI Verification.

The Nondeterminism Dilemma in Aviation Certification

Civil aviation authorities (FAA, EASA) require DO-178C DAL A certification for flight control software, mandating 100% Modified Condition/Decision Coverage (MC/DC) and zero nondeterministic behavior. Modern probabilistic neural networks cannot satisfy this standard directly.

Run-Time Assurance (RTA) Architecture

AvionicsAgentic applies ASTM F3269 Run-Time Assurance: the complex neural agent proposes trajectory maneuvers, but a deterministic, formally verified safety monitor evaluates the command. If the proposed bank angle or pitch rate risks envelope violation, the command is instantly intercepted and replaced with standard recovery inputs.

ASTM F3269 Run-Time Assurance: Wrapping complex AI agents with deterministic safety monitors.
Switching Logic: Instantly transferring control to a simple certified backup controller upon anomaly.
Reachability Analysis: Mathematically proving that the aircraft cannot exit the safe flight envelope.
Tool Qualification: Validating formal verification tools under RTCA DO-330 criteria.
