Who among the following would wear a purple jersey on the flight deck?

The individual who wears a purple jersey on the flight deck is responsible for aviation fuel operations. This role is critical as it involves the safe handling and transfer of fuel to aircraft, and the distinct color of the jersey signifies their specialized training and responsibilities. Wearing the purple jersey allows for quick identification of personnel who are dedicated to fueling operations, which is essential for maintaining safety and efficiency on the flight deck, where hazardous materials are handled.

In contrast, maintenance personnel typically wear a different color to identify their role, as both maintenance and fuel operations involve distinct tasks and safety protocols. The arresting gear officer, responsible for using the cable designed to stop aircraft during landing, would also not wear a purple jersey, nor would the crash crew which is tasked with emergencies and firefighting on the flight deck. Each of these roles is recognized by their unique jersey colors, reinforcing the importance of efficiency in coordinating operations on the flight deck.
