Is the AFT FA required to conduct a preflight inspection of the cabin communication system on the ERJ 175?

The AFT FA is not required to conduct a preflight inspection of the cabin communication system on the ERJ 175, as this task is generally designated to the flight crew or maintenance personnel. The responsibilities of an AFT FA typically include ensuring the safety and comfort of passengers, conducting safety demonstrations, and preparing the cabin for flight. While each airline may have specific procedures in place regarding safety inspections, the fundamental requirement for inspecting cabin systems often falls within the realm of the flight deck crew rather than the flight attendants.

Because of this division of responsibilities, it is not within the duties of the AFT FA to perform a preflight inspection on the communication system; rather, they will rely on the flight crew to handle such technical checks as part of their preflight protocols. Other choices imply varying responsibilities or conditions under which an inspection might be needed, but those do not align with the standard procedure for the ERJ 175.
