ATPL Mass And Balance Practice Test

The correct choice indicates that when 60 kg is spread over 11 square feet, it results in a distribution load calculated by dividing the total weight by the area over which it is spread. This gives a load per square foot of 5.45 kg/ft², which is the primary means of evaluating how the weight is distributed across a given area.

This calculation is important in mass and balance considerations because it helps engineers and pilots understand how weight affects the structural integrity and balance of the aircraft or other structures. The distribution load demonstrates how concentrated or spread out the weight is, which can influence flight dynamics and safety.

While considering other options, it is clear that the total load limit and maximum linear load pertain to broader concepts not specifically addressing the direct calculation of load per square area. The average weight distribution could imply a more general interpretation that does not focus on the specific calculation arrived at with the given figures. Thus, the emphasis on calculating load per unit area is critical in this context, making it evident why the distribution load is the correct interpretation of the scenario.
