In terms of safety, why should hoses not pass underneath an aircraft during fueling operations?

During fueling operations, ensuring safety is the paramount concern. Hoses should not pass underneath an aircraft primarily to reduce the risk of accidents. Aircraft are typically large and heavy vehicles, and if hoses are placed underneath, they become a tripping hazard or can be inadvertently damaged by the aircraft's movement or by personnel moving around. An accidental disconnect or rupture can lead to fuel spills, which pose a fire hazard and create environmental risks.

Additionally, the visibility of operations is compromised when hoses pass under the aircraft, which can lead to confusion about their status or positioning. Proper hose management not only ensures safety for personnel and equipment but also contributes to smooth and efficient fueling operations. This emphasis on minimizing risk and maintaining control over the fueling environment makes avoiding the placement of hoses underneath the aircraft a critical practice in tactical fuel systems operations.
