Which doors are initially blocked as exits for a water landing?

• A. 2L and 2R
• B. 1L and 1R
• C. 3L and 3R
• D. 2L and 3R

Answer: (A)

When evacuating a aircraft on water, the crew plans which exits to use first to keep everyone safe and to get life rafts into the water quickly. On the 737-700, the doors located over the wings are blocked at the start of a ditching. The forward and aft doors are the primary exits in a water landing because their slides can be deployed as life rafts and provide stable access to the flotation devices. Opening the wing exits first could allow more water into the cabin or complicate raft deployment, so those wing exits are held back initially. Once the situation is under control and rafts are in position, the wing exits can be considered if needed.
