Which statement describes not an acceptable means to ensure safety for an unproven high-power rocket?

• A. Fly it as a heads up flight on the first flight
• B. Fly a smaller (non-HPR) scale model
• C. Perform a swing test
• D. Use a simulation program

Answer: (A)

The key idea is preventing high-risk, unproven flights by proving the design is safe and predictable through careful testing and analysis before attempting a full-power launch. Using a smaller non-HPR model lets you observe overall behavior and verify stability and recovery on a scale similar in dynamics but without the full power and risk. A swing test directly checks static and dynamic stability by ensuring the center of gravity and center of pressure give a healthy stability margin and that the airframe won’t tumble in flight. A simulation program lets you model thrust, weight, drag, and stability ahead of time, giving you insight into expected performance and potential issues without risking hardware or people. Flying the unproven high-power rocket on its first flight as a heads-up launch bypasses these essential verifications and introduces high risk of failure and harm, so it’s not an acceptable safety approach.
