Where are the standard weights of people generally found?

The standard weights of people are typically found in the TC AIM (Transport Canada Aeronautical Information Manual) under section RAC 3.4. This section provides guidance and information regarding weight and balance calculations, which is crucial for pilots to understand in order to meet aircraft performance and safety regulations. Standard weights are important for ensuring that the aircraft is properly loaded and that weight limits are not exceeded, thereby enhancing safety during operation.

While the FAA regulations, pilot training manuals, and aircraft maintenance manuals may contain valuable information relevant to flight training and aircraft operation, they do not specifically provide the standardized weights of individuals as comprehensively as the TC AIM does. The TC AIM serves as a primary reference for Canadian pilots, which is why option A is the most appropriate choice in this context.
