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

The correct response is that the AFT FA is not required to conduct a preflight inspection of the cabin communication system on the ERJ 175. Preflight inspections are generally conducted to ensure that all necessary equipment and systems that are critical for safety and operational procedures are functioning correctly. However, the specific operational procedures for cabin communication systems may designate that such inspections are not a requirement for every flight or may be covered by other routine checks performed by maintenance staff.

It's essential to understand that certain systems, such as cabin communication, may not require a checklist inspection by flight attendants unless there is a confirmed issue or malfunction reported prior to the flight. This allows for efficient use of crew resources without compromising safety, as regular maintenance is performed on these systems per the airline's operational guidelines.
