What is the average weight of an adult according to the FAA?

The average weight of an adult according to the FAA is recognized as 170 lbs. This figure is significant in aviation for various reasons, particularly in weight and balance calculations, which are crucial for ensuring the safety and efficiency of aircraft operations. Proper weight estimations contribute to maintaining the aircraft's center of gravity within safe limits and help in determining performance characteristics like take-off and landing distances. The FAA's data on average weights is typically based on comprehensive surveys and studies to reflect profile averages for different demographics.

Understanding this average aids pilots, flight planners, and maintenance personnel in making informed decisions regarding passenger and cargo loads, which in turn supports compliance with safety regulations. The other weight options exceed or fall below the FAA standard and would not be an accurate representation for the calculations necessary in aviation practices.
