FAQs
The main objective is to ensure that airborne electronic hardware is thoroughly tested for resilience and reliability under extreme conditions and abnormal scenarios, in compliance with the RTCA DO-254 standard.
Robustness testing typically includes environmental stress tests, fault injection, boundary condition analysis, power cycling, EMI/EMC testing, and recovery mechanism verification.
The process should involve hardware test engineers, reliability engineers, systems engineers, and safety analysts to ensure comprehensive test coverage and analysis.
Robustness testing helps identify potential failure modes and system weaknesses under extreme conditions, allowing for design improvements that enhance the overall safety and reliability of airborne systems.
While some robustness tests can be performed earlier, comprehensive robustness testing is typically conducted during the later stages of development, after functional verification and before final certification testing.
