On the 764 model, which doors are equipped with double lane slide rafts?

• A. Doors 1, 3, 4
• B. Doors 2, 3, 4
• C. Doors 1, 2, 4
• D. Doors 1, 2, 3

Answer: (C)

Double-lane slide rafts are used on doors that must provide the highest evacuation capacity and, in water ditching, also serve as rafts. Not every main door gets this configuration because adding two slides increases weight and packaging needs, so the aircraft pairs the double-lane system with the doors that have the largest expected passenger flow or the most favorable geometry for two slides. For the 764 model, the doors that get the double-lane slides are the doors at positions 1, 2, and 4. Door 3 does not have the double-lane setup, due to its location and the associated space/weight considerations. So the correct doors with double-lane slide rafts are 1, 2, and 4.
