What are "standard weights" in weight and balance calculations?

Standard weights in weight and balance calculations refer to the predetermined average weights assigned to various components, such as passengers, baggage, and fuel. These standard figures are used because they provide a consistent basis for calculating weight and balance, ensuring that aircraft operations remain safe and efficient. By using standard weights, operators can estimate the impact of loading configurations on the aircraft's center of gravity and overall performance without having to weigh each individual component every time.

For example, the FAA provides average standard weights for passengers and baggage, which helps in planning for flight safety and ensuring compliance with weight limits. Utilizing these standard weights allows for easier and more reliable calculations, which is critical for flight planning and maintaining aircraft performance during operation.
