• A. True
• B. False
• C. Only in case of cabin fire
• D. Only with permission from the pilot

Answer: (A)

The statement that the interphone cannot be used to signal an emergency to the cabin on the A321/321 neo is true. In this aircraft, the interphone system is primarily designed for communication between the flight crew and the cabin crew or among cabin crew members. While it is a vital tool for operational communications, protocols are established to ensure that emergency situations are effectively managed.

In the case of an emergency, signaling to the cabin typically relies on other methods, such as activating emergency alarms or utilizing specific cabin signals, rather than the interphone system. This distinction helps to ensure that communication during an emergency is clear, direct, and adheres to the established emergency procedures, which might include the use of visual signals or specific emergency announcements. Understanding the limitations and intended uses of the interphone system is crucial for the crew to ensure effective communication in various situations, especially during emergencies.
