How to make an announcement on A350?

• A. For cabin and crew rest: Hold PPT bar
• B. For all cabin zones: Press PA and hold PPT bar
• C. For a specific cabin zone: Press PA +1 or 2 and hold PPT bar
• D. For the bridge crew: Press PA twice and hold PPT bar

Answer: (A)

The key idea is how to use the cabin PA/interphone system to reach passengers and crew rest. On the A350, a general cabin announcement is made by using the Push-To-Talk control. You press and hold the PPT bar so your voice is transmitted through the cabin speakers. Keep holding it while you speak, then release when you’re done. This path is used to address the entire cabin and crew rest area without selecting a specific zone.

The other options imply dialing a particular zone or contacting the cockpit separately, or combining PA with a zone selection, which isn’t how a standard cabin announcement is conducted. For a broad message to the cabin, holding the PPT bar is the correct approach.
