Choosing the longest side for floor running load calculations is significant because it optimizes balance and stability during flight. When calculating load distribution, positioning heavier items along the longest side allows for a more even weight distribution across the aircraft's structure. This is critical for maintaining the aircraft’s center of gravity within safe operational limits.

An optimal balance of weight contributes to the aircraft's stability in flight, ensuring that it reacts predictably to control inputs and environmental factors. If the load is unevenly distributed or placed too far forward or aft, it can lead to handling difficulties, increased drag, or in severe cases, a safety hazard. This makes the selection of the longest side essential for ensuring the performance and safety of the aircraft.

While other options may seem relevant, such as reducing calculation complexity or ensuring compliance with weight limitations, the primary reason for this practice lies in achieving an optimal balance, which directly correlates with safe flight operations. Accurate performance data is also essential; however, if the balance is not addressed first, the data derived may not reflect safe operational conditions.
