Research and Application of Function Requirements Validation Process for Civil Aircrafts Based on ARP 4754A

The application of ARP 4754A-based Function Requirements Validation Process (FRVP) for civil aircrafts ensures the integrity and rationality of verifying aircraft-level requirements, and facilitates the fidelity of aircraft-level requirements definition. The Top-Down design of aircraft-level FRVP is carried out in this study based on ARP 4754A. By employing methods such as requirements review, requirements trace, and requirements analysis, the process of validating these requirements is presented. Furthermore, each step involved in the validation is studied in depth to ensure their completeness, correctness, and rationality.
