What does the cabin ready switch control on the A350?

• A. Activates the galley waste disposal units
• B. Notifies the FD crew that cabin is ready for takeoff
• C. Opens the cabin crew rest door
• D. Powers the heated floor panels

Answer: (B)

The cabin ready switch is a signaling function from the cabin to the flight deck. When the cabin crew has completed securing the cabin and is in the final stages of prepared for takeoff, they press this switch to inform the pilots that the cabin is ready for departure. The flight crew then has this explicit confirmation to proceed with the takeoff flow, coordinating with the pilots and cabin status. This switch does not control galley waste disposal, open a cabin crew rest door, or power heated floor panels; those systems have separate controls and purposes.
