Which item is NOT required for Flight Attendants to carry during duty?

The flight manual is not required for flight attendants to carry during their duty precisely because it is typically housed in a central location on the aircraft, such as in the cockpit or a designated area intended for official documentation. Flight attendants are trained on this material but do not need to carry the physical manual with them during each flight.

On the other hand, items such as a SkyPro device and its chargers, a pen for necessary documentation, and a working watch to manage timing during the flight are essential for the effective performance of their duties. The SkyPro provides access to critical information and resources, while a pen is vital for noting down important details or completing forms. A working watch ensures that flight attendants can keep track of timings related to safety protocols and passenger service throughout the flight.
