How is cargo typically loaded in bulk cargo compartments?

The correct choice highlights the common practice of loading bulk cargo, which is generally done in a way that allows for flexibility in placement. When loading cargo in bulk compartments, the primary focus is on ensuring that the cargo is secured properly using tie downs and cargo nets to prevent movement during flight.

This method of loading is advantageous because it can streamline the loading process, allowing for quicker and more efficient handling. Since bulk cargo can vary greatly in type and weight, it is often impractical to load everything in a strictly predetermined order. Instead, the focus is on securely containing the cargo to maintain overall safety and balance.

While there can be some guidelines related to weight distribution, the essential requirement is that the cargo is adequately secured to meet safety standards during transit. Therefore, the use of tie downs and cargo nets becomes critical to prevent shifting or movement, regardless of the order in which items are loaded. Thus, allowing for some unpredictability in loading can aid operational efficiency while still adhering to safety requirements.
