What should pilots do if they see an error in the Aircraft Quick Reference page?

When pilots notice an error in the Aircraft Quick Reference page, cross-checking with the Pilot's Operating Handbook (POH) or the Aircraft Flight Manual (AFM) is the appropriate action. This step is crucial because the POH/AFM provides comprehensive and validated information regarding aircraft operations, including limitations, procedures, and systems. By consulting the POH/AFM, pilots can confirm whether the information in the QRH is indeed incorrect and determine the appropriate corrective action. This process ensures that the pilots are acting on the most accurate and reliable data to maintain flight safety.

Additionally, while other options may seem plausible, they do not provide the immediate and effective resolution needed in this situation. Consulting the co-pilot may lead to a discussion, but does not address the error directly. Ignoring the error due to time constraints can potentially lead to unsafe situations, and simply reporting to the manufacturer might not resolve the issue at hand during the flight. Therefore, cross-checking with the POH/AFM stands out as the most effective and responsible action.
