Which of the following is not a required manual app for duty items?

The correct answer is that a Weather Report is not a required manual app for duty items. In a flight environment, duty items typically include essential manuals and checklists that cabin crew must refer to in the course of their duties, such as the Emergency Procedures and safety protocols, which are covered in the EFAOM (Emergency Flight Attendant Operations Manual) and EFAAB (Emergency Flight Attendant Awareness Briefing). The Safety Checklist is also critical for ensuring the safety and preparedness of the crew and aircraft before departure.

While a Weather Report is important for flight operations and influences overall flight planning and passenger safety, it is not categorized as a core manual app that flight attendants are required to have on hand for duty items. Instead, it serves as supplementary information that, while valuable, does not directly pertain to the immediate responsibilities outlined in the mandatory manuals and checklists used by flight attendants.
