flight testing

Flight testing is the process of testing an aircraft, spacecraft, or other aerospace vehicle in flight to evaluate its performance and safety. This is a critical part of the aerospace industry's product development cycle. Before flight testing, extensive ground testing is conducted to verify design integrity, including static and dynamic tests on airframes and rigorous checks of ancillary equipment, engines, and systems.12

For spacecraft and missiles, which are often uncrewed and expensive to launch, prototype test flights are rare. Instead, extensive ground-based simulations and highly detailed pre-flight checks are employed to ensure operational readiness and prevent costly failures. Flight certification regulations govern these tests, ensuring aircraft meet stringent performance standards under various conditions before entering service.23
