How is passenger weight calculated for an aircraft?

Passenger weight calculation for an aircraft must include all factors that contribute to their overall weight, making the total weight representative of the actual load the aircraft will carry. This total includes not only the body weight of the passengers but also their clothing and any personal items they might be bringing aboard.

By using the weight of passengers including clothing, the calculation reflects a more accurate representation of the weight that affects the aircraft's performance, center of gravity, and overall safety. It ensures that the aircraft is properly loaded and within its weight and balance limitations, which are critical for safe flight operations.

Using data about average passenger weights based on demographic information might be somewhat relevant in estimating weights for larger groups, but it lacks the precision needed for individual passenger calculations on a specific flight. The weight of passengers only during boarding does not consider their weight during flight conditions, which is necessary for accurate operational calculations.
