Which of the following is NOT one of the components of total airplane weight?

Total airplane weight is comprised of several key components that directly contribute to the overall operational weight of the aircraft. These components typically include the weight of the airplane itself, which encompasses the airframe, engine, and essential systems. Fuel weight is another significant factor, as the amount of fuel carried directly impacts both the weight and performance of the aircraft. Additionally, the passengers and their baggage also contribute to the total weight, as their presence and cargo must be accounted for when calculating load and performance metrics.

Weather conditions, however, do not constitute a physical component of airplane weight. While weather can affect flying conditions, aircraft performance, and handling, it does not add to or subtract from the actual weight of the airplane. Instead, pilots must consider weather when planning flights, but it remains an external factor that does not factor into total weight calculations. Thus, the correct answer identifies weather conditions as the component that is not part of total airplane weight.
