What organization regulates weight and balance standards for aircraft?

The correct choice is the FAA, or Federal Aviation Administration. The FAA is the primary regulatory body in the United States responsible for ensuring the safety of civil aviation. This includes establishing and enforcing standards related to the weight and balance of aircraft. Proper weight and balance are critical for safe flight operations, affecting stability, control, and overall performance of the aircraft.

The FAA provides guidelines on how to calculate weight and balance and mandates that pilots and operators adhere to these standards to maintain safe operational procedures. By regulating these standards, the FAA helps to reduce the risk of accidents that can occur due to improper loading or weight distribution.

Other organizations, while related to aviation safety and regulation, have different roles. The NAA (National Aeronautics Association) focuses on promoting aviation and supporting the growth of the industry, but it does not regulate weight and balance standards. The NTSB (National Transportation Safety Board) investigates accidents and makes safety recommendations, but it does not set regulations or standards. The ICAO (International Civil Aviation Organization) provides guidelines for international aviation but does not enforce regulations at the national level within the jurisdiction of the FAA. Thus, the FAA is the authoritative body for weight and balance regulations in the U.S. aviation sector.
