Avionic Test Device In-Flight Data Simulation

The patent applies preliminary action by performing ground validation simulations before actual in-flight testing. The ground validation module pre-processes flight data and validates avionic functions using simulated environments, preparing test cases and expected outcomes in advance. This preliminary validation reduces the need for extensive in-flight testing while maintaining reliability, as the function is pre-certified before deployment to aircraft.

The patent uses copying by creating virtual copies of flight environments and avionic systems through simulation. The ground validation module replicates real flight conditions and system behaviors in a controlled ground-based environment, allowing comprehensive testing without requiring actual flight hours. This virtual copying enables thorough validation while significantly reducing development time and aircraft usage.

The patent applies extraction by selectively extracting only the necessary flight data parameters required for validating specific avionic functions. Rather than collecting and processing entire flight databases, the system identifies and extracts relevant data elements (e.g., specific sensor readings, flight conditions) needed for the validation task. This targeted extraction maintains measurement precision while dramatically reducing data volume and processing requirements.

The patent applies local quality by tailoring the data collection and processing approach to each specific validation requirement. Different avionic functions require different data subsets and analysis methods. The system adapts its data processing locally to match the specific validation needs, applying appropriate precision and depth only where necessary rather than uniformly across all data. This optimizes the balance between measurement precision and data processing complexity.
