Flight Telemetry Metrics: < 50 µs (Co-Simulation Time-Sync Skew) | 100x (Faster-than-Real-Time Regression Speed) | 10,000+ (Automated Edge Failure Scenarios Run) | 99.4% (Physical Flight Data Correlation Accuracy)

Transforming Aircraft Development with Cyber-Physical Twins

Traditional iron bird test rigs cost tens of millions of dollars, occupy vast hangars, and create scheduling bottlenecks for flight test engineers. AvionicsTwins replaces physical wiring looms and hardware boxes with cloud-native, real-time hardware-in-the-loop (HIL) simulators capable of running automated regressions across hundreds of virtual aircraft simultaneously.

Core Engineering Areas

Virtual Iron Bird HIL — Replacing massive hangar-scale mechanical rigs with distributed cyber-physical software emulators.
Bus & Network Emulation — Simulating complex deterministic airborne networks with bit-level timing precision and buffer modeling.
Predictive Fleet Health — Streaming aircraft telemetry into cloud twins to forecast actuator failures and optimize airline turnaround times.
