Which item is considered essential in the required duty items?

A working flashlight is considered essential among the required duty items for flight attendants because it is critical for safety and efficiency, especially during emergency situations or when visibility is low. Flight attendants may need to navigate dark cabins or aircraft exteriors, and a reliable source of light ensures they can perform their duties effectively.

In emergencies, a flashlight assists in guiding passengers during evacuations and locating emergency equipment. Given the nature of their responsibilities, having a working flashlight readily available is not just practical; it's a safety necessity to ensure the well-being of both crew and passengers.

While personal laptops, extra uniforms, and food supply bags can support a flight attendant's functions, they do not carry the same level of essentiality tied directly to safety and operational readiness as a working flashlight does.
