Question 3608 Deck General

The correct answer is C) static grounding device. Each hose in the fuel transfer system for helicopter refueling must have a static grounding device to prevent the buildup of static electricity, which could cause a dangerous spark and fire hazard during the refueling process. The static grounding device ensures that any static charge is safely dissipated, reducing the risk of ignition. The other options are incorrect because a quick-disconnect nozzle is used to quickly and safely stop the fuel flow, a splash guard is to prevent fuel spills, and a vapor recovery system is to capture and contain fuel vapors, but they do not specifically address the need for static electricity control during helicopter refueling.
