Which regulations govern payload distribution for commercial flights?

The regulations that govern payload distribution for commercial flights fall under the jurisdiction of the Federal Aviation Administration (FAA). The FAA is responsible for overseeing and enforcing the safety standards and regulations related to air travel in the United States. This includes guidelines for the loading and balance of aircraft to ensure safe flight operations. Proper payload distribution is essential to maintain the aircraft's center of gravity within safe limits, thereby ensuring stability and control during flight.

In contrast, the other organizations mentioned do not specifically focus on aviation safety and payload management. The International Maritime Organization (IMO) deals with maritime safety and environmental protection rather than aviation. The United Nations provides a broad range of international guidelines and normative frameworks but does not specifically regulate commercial flight operations or payload distribution. The American Medical Association (AMA) primarily focuses on healthcare and medical ethics rather than aviation. Thus, the FAA is the relevant authority for regulations governing payload distribution in commercial aviation.
