test software: A technical guide
4 Criteria to choose your test software
Airworthiness Safety Certification Compliance
Software must facilitate rigorous verification and validation processes necessary for meeting stringent EASA and FAA airworthiness safety standards.
Real-time Deterministic Latency
High-fidelity systems require guaranteed execution timing to validate flight-critical flight control laws and sensor fusion algorithms accurately.
Hardware-in-the-loop Integration
Seamless interfacing with physical avionics hardware ensures comprehensive testing of actual flight components within simulated operational environments.
End-to-end Requirements Traceability
Mandatory mapping from high-level system requirements to low-level test cases ensures full coverage for certification audit trails.
Available technologies and advantages
Model-Based Testing Frameworks
Unlike manual scripting, these tools generate test cases from models, improving coverage. They offer superior consistency but require significant engineering investment in simulation models.
Hardware-in-the-Loop Simulation
Contrasting with pure simulation, these platforms execute real-time tests on physical components. They provide necessary physical validation but involve high hardware costs and complex setups.
Automated Static Analysis
Compared to dynamic testing, these tools scan source code without execution. They identify structural defects early but cannot detect runtime logic errors or timing violations.
