Which doors are equipped with dual-lane slide/rafts?

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

Answer: (A)

Dual-lane slide/rafts are used to maximize evacuation capacity and provide life-raft capability if the aircraft must ditch. They give two parallel paths for passengers to exit and can also function as rafts when the aircraft is in water. Because of this, they’re placed on exits that carry the highest potential load and can accommodate two slides without conflicting with interior layouts or wing structures. The mid-to-rear doors are the logical locations for this arrangement, since they serve as the primary high-capacity exits while keeping weight and complexity manageable. The forward doors are typically equipped with single-lane slides to save weight and because they handle a smaller immediate evacuation flow. So the doors in the middle and aft sections are the ones equipped with dual-lane slide/rafts.
