What items must be secured with straps in the bin planned for loading?

In the context of securing items in a cargo bin, the focus is on maintaining stability and safety during transport. The correct answer emphasizes the importance of securing sharp, dense, heavy items with straps. These types of cargo can easily shift during handling or in transit, posing risks not only to the integrity of the items themselves but also to the safety of the aircraft and its crew.

Heavy items can exert significant force if they move unexpectedly, which can lead to imbalances in the aircraft's weight distribution. This can compromise the aircraft's handling and stability. Sharp items, on the other hand, can cause damage to other cargo or present hazards if they are not secured properly. Therefore, using straps ensures that these items remain in place and reduces the risk of injury or damage effectively.

In contrast, fragile items, lightweight cargo, and electronics may have different handling guidelines. Fragile items may require protective cushioning or different types of restraints to prevent breakage rather than simply relying on straps. Lightweight cargo, while potentially needing to be secured, does not pose the same level of risk in terms of weight-related movement. Electronics generally need specialized handling to protect sensitive components, which may include static protection as much as physical restraint.

Overall, the need to secure sharp, dense,
