Which of the following is NOT typically included in aviation documentation?

Passenger feedback is not typically included in aviation documentation for operational and safety purposes. Aviation documentation predominantly focuses on elements that guarantee safety, regulatory compliance, efficiency, and operational integrity. Key documents like load calculations are essential for ensuring that the aircraft is within weight limits for safe flight, and duty hours are meticulously recorded to prevent fatigue among crew members, thus maintaining safety standards. Daily diaries may record operational activities and maintenance logs to track aircraft condition and compliance with regulations.

In contrast, while passenger feedback can be valuable for service improvement and customer satisfaction, it is not a formal requirement in aviation safety documentation. Therefore, it does not serve the same critical role as the other options, which are directly tied to the operational safety and regulatory needs of aviation.
