Why is it essential to secure an aircraft's cargo door?

Securing an aircraft's cargo door is crucial primarily to prevent safety hazards. An unsecured or improperly secured cargo door can lead to various dangerous situations, such as the door inadvertently opening during flight or taxiing. This could result in cargo spilling out, which poses a significant risk to people and property both on the ground and in the air. Additionally, it can lead to further complications affecting the aircraft's structural integrity and overall safety. Ensuring that the cargo door is locked and secure helps maintain the safety of passengers, crew, and those on the ground, making it a top priority during ramp operations.

While securing the cargo door does contribute to overall aircraft balance and could indirectly support fuel efficiency and minimize noise, the primary reason is the immediate safety concerns related to unsecured cargo.
