Which document confirms the maximum gross weight of an aircraft?

The Certificate of Airworthiness is the document that confirms the maximum gross weight of an aircraft. This certificate is issued by the aviation regulatory authority and indicates that the aircraft meets the necessary safety and operational requirements. Part of the information documented in the Certificate of Airworthiness often includes the maximum gross weight, which is essential for ensuring that operations comply with the standards for safe flight.

In the context of aircraft operation, knowing the maximum gross weight is crucial for considerations such as takeoff and landing distances, fuel requirements, and overall flight safety. While the other options provide valuable information regarding the operation and management of the aircraft, they do not specifically serve to confirm the maximum gross weight in the same manner as the Certificate of Airworthiness does. The Weight and Balance document, for instance, provides a detailed assessment of how the aircraft's load should be distributed, but it relies on the maximum gross weight as specified in the Certificate of Airworthiness. The Pilot Operating Handbook contains operational limits and performance data but does not serve as an official confirmation of maximum gross weight. The Journey Log is used to record the aircraft's operational history but does not include weight specifications.
