How is CG validation conducted relative to actual loaded weights?

• A. CG is not validated after loading.
• B. CG is validated only for long-haul flights.
• C. CG is checked after landing.
• D. CG is validated by recalculating CG using actual loaded weights against approved data.

Answer: (D)

Weight and balance validation relies on the actual loaded weights to confirm the aircraft’s CG is within approved limits for the given configuration. After loading, you record the real weights of passengers, baggage, cargo, and fuel, then calculate the total weight and the moment (weight times its arm) to determine the exact CG position. This calculated CG is then compared to the published CG limits for that specific loading and fuel state. If the CG falls within the allowed envelope, the flight can proceed; if not, you adjust the load distribution or fuel to bring the CG back into tolerance. This approach ensures accuracy because it uses what’s actually on the airplane, not estimates or standard values.

CG validation isn’t done after landing, and it isn’t only for long-haul flights; it’s essential for every flight configuration. Nor is CG validated by simply accepting nominal data—it must be recalculated with the real weights to verify compliance.
