Which flight testing stage is specifically aimed at validating the integrated performance of multiple subsystems within an aircraft?

• A. Ground tests
• B. Component tests
• C. System-integrated tests
• D. Certification

Answer: (C)

When multiple subsystems must work together, their interactions and interfaces need to be verified in a coordinated way. System-integrated tests are designed to validate how the different parts of the aircraft perform as a combined system, ensuring that signals, control laws, power, data exchange, and environmental effects all mesh correctly in real flight conditions. This stage checks that the integrated performance meets overall requirements, not just how an individual component behaves in isolation. For example, it tests how avionics, flight controls, hydraulics, sensors, and actuators respond together, ensuring the aircraft behaves predictably across the intended flight envelope. Ground tests and component tests focus on individual parts or static behavior, and certification is the formal end-goal of showing airworthiness. So, the phase that specifically targets the coordinated operation of multiple subsystems is system-integrated testing.
