How is the floor running load calculated in relation to the aircraft?

The calculation of the floor running load involves determining how the weight of the load is distributed along the aircraft’s fore and aft axis. This allows for an accurate assessment of how the load affects the aircraft's center of gravity (CG). In this context, dividing the weight by the length of the load along this axis provides a clear metric on how the load is spread out and its influence on the overall balance of the aircraft.

This method is crucial because it ensures that the aircraft remains within safe weight and balance limits, which are essential for optimal flight performance and safety. Understanding how the weight interacts with the different dimensions of the aircraft helps in making informed decisions regarding loading procedures and ensuring compliance with operational guidelines.

In contrast, other options either misrepresent the relationship between weight and distance or do not utilize a proper mathematical approach to calculate the running load effectively. By focusing on dividing the weight by the length of the load, the correct method ensures a precise understanding of how loads will affect the aircraft dynamics during operation.
