Core aerospace engineering and protocols for Automated Fault Injection.
Federal aviation regulations mandate that no single hardware failure or software anomaly can prevent continued safe flight and landing. Proving this requires subjecting the avionics system to thousands of simulated electrical and sensor failures.
Avionicsimulator incorporates solid-state Fault Insertion Units (FIUs): during automated overnight test runs, the system systematically shorts sensor lines, severs communication channels, and injects corrupted packets, recording whether the flight computer detects the fault and successfully transitions to backup mode.
