What is the standard average passenger weight currently recommended by the FAA, including carry-on baggage in summer?

The correct answer reflects the current FAA recommendation that incorporates both the average weight of passengers and their carry-on baggage during the summer months. As air travel continues to evolve, the FAA periodically updates weight standards to ensure safety and efficiency in flight operations. The adoption of an average passenger weight of 190 pounds is based on various factors, including historical data and trends observed in passenger demographics and behaviors. This weight takes into account the increase in average body weight over the years as well as typical carry-on baggage that passengers often bring aboard, thus providing a realistic and practical guideline for airlines when calculating load and balance for aircraft. This standardization helps airlines to optimize performance, fuel efficiency, and overall safety during summer operations when passengers may be more likely to travel with additional belongings.
