What is one method of controlling aircraft loading?

Utilizing weight distribution charts is crucial for controlling aircraft loading because these charts provide detailed information on how to distribute cargo throughout the aircraft in a way that maintains balance and stability during flight. Proper weight distribution is essential for safe aircraft operation, as uneven loading can lead to difficulties in handling and increased risk of accidents. Weight distribution charts help ensure that the center of gravity remains within acceptable limits, thereby enhancing safety and efficiency.

The other methods mentioned may lack the precision and safety considerations required for effective aircraft loading. For example, random loading techniques could lead to imbalances, while counting cargo only after loading does not ensure that the load is distributed properly before the flight. Loading items based on color does not provide any relevant information concerning weight or balance, making it an ineffective strategy for aircraft loading management.
