Civil vehicles, commonly seen as complex products, involve many high-tech aspects, several fields working together, many investments spent on projects, and challenging management. Through the entire life-cycle of aircraft development, the application of requirement-driven systems engineering methodologies helps to manage the aircraft development process while addressing the needs of the market and of stakeholders. The operational needs of an aircraft are design inputs for aircraft development, and the precision, authenticity, and comprehensiveness of these needs influence the efficiency of the development processes and the quality of the products. When the design and research-and-development activities are based on accurate and complete needs, the development interval for such projects can be shortened significantly, and the costs of R&D lowered. Especially because it is one of the fundamental phases of establishing whether aircraft meet the design requirements, design verification is becoming one of the most critical stages of civil aircraft development. Consequently, designing a more methodical and effective way of verifying designs becomes a central theme in current aviation technology development.
There is a human-centered design verification approach that emphasizes requirement-oriented processes, using systematic requirement analysis and conceptual design procedures in order to maximize the congruency between design results and intended requirements. This study aims to perform a holistic analysis of the aircraft design validation process that is based on research, while offering some innovative techniques and strategies for civil aviation on effective validation practices.
