Which doors on the A350 have single-lane slide/rafts?

• A. Doors 1L/1R
• B. Doors 2L/2R
• C. Doors 3L/3R
• D. Doors 4L/4R

Answer: (A)

Single-lane slide/rafts are chosen based on the size and location of the door and how quickly evacuees can move through that doorway. On the A350, the forward doors at the nose, 1L and 1R, are configured as single-lane exits, so their slides deploy as a single evacuation lane that forms a raft if needed. This setup matches the door geometry and the required speed of evacuation from the forward cabin. The other doors have different slide configurations (larger doors or doors that support multiple lanes or additional rafts) to handle higher flow or specific structural layouts, so they are not single-lane.
