When loading aircraft, which principle should be followed?

The principle of "First in, last out" is crucial when loading aircraft, especially in the context of helicopter operations where balance, weight distribution, and accessibility of equipment are important for safety and efficiency. This principle ensures that the items that are loaded first into the aircraft are those that are least likely to be needed during flight, which can be critical during emergency situations or when the aircraft lands and immediate access is required.

By following this principle, loading can be managed in a way that allows for organized access to the most essential equipment or personnel without needing to unload items that are not immediately necessary. This practice also aids in maintaining the center of gravity and stability of the aircraft during flight, reducing the risk of complications while the helicopter is in operation. Essentially, this method ensures operational efficiency and enhances safety for both the crew and passengers.
