Which statement correctly describes the A330's escape devices?

• A. Doors 1, 2, and 4 have double lane slide/rafts; Door 3 has a single lane slide that can be used as a flotation device
• B. Doors 1, 2, and 3 have double lane slides; Door 4 has a single lane slide
• C. All doors have double lane slides
• D. No slides on any doors; all exits use rafts

Answer: (A)

Escape devices at passenger doors come in two main flavors: double-lane slides that can function as flotation rafts, and single-lane slides that can still be used as a raft if needed. On the A330, most door exits are equipped with double-lane slide/rafts to provide rapid egress and sufficient raft capacity for several exits at once. One exit uses a single-lane slide that can still be used as a flotation device, which saves weight while maintaining flotation capability. This combination matches the aircraft’s design needs: quick evacuation through multiple doors with ample raft availability, balanced by the lighter single-lane option at the specified exit.
