On A321 door configurations, which reports to SCCM in interphone?

• A. Reports to CMDR
• B. Reports to SCCM in interphone
• C. Reports to SCCM verbally
• D. Reports to 4L interphone

Answer: (B)

The key idea is how certain cabin events are routed to the supervisory role aboard the aircraft. For door configurations on the A321, the standard channel to relay status or reports is the interphone to the SCCM. This ensures that the cabin supervisor can quickly coordinate safety and door-related concerns with the rest of the cabin team and with the flight deck as needed. The SCCM is the designated point of contact for these cabin-wide communications, so reports flow through the interphone to SCCM rather than directly to the commander or through a verbal message. The other options describe different, less appropriate pathways for this type of report.
