What are the two limits to consider for floor loading?

The correct choice highlights the importance of load distribution and intensity, as these factors are critical in ensuring the safety and structural integrity of an aircraft during operation.

When considering floor loading, it is essential to understand the distribution load intensity, which refers to how weight is spread over the area of the floor structure. An even distribution is crucial to prevent excessive stress on any part of the floor, which can lead to structural failure. The running load refers to the weight carried by the aircraft as it operates, taking into account dynamic factors that may increase this load during maneuvers or turbulence.

Recognizing these two aspects allows operators to ensure that they do not exceed the floor's load-bearing capacity, thereby maintaining safety and compliance with regulatory standards. This understanding aids in avoiding potential accidents resulting from floor overloads, which could compromise aircraft performance and passenger safety.

Other choices focus on different considerations that, while relevant to cargo loading, do not specifically address the critical aspects of floor loading limits. Understanding the intensity and distribution of the load is fundamental for proper weight management and structural safety in aircraft operations.
