Boeing 787 KSV Practice Test

Two 3-tiered carts are used on the 787-9 to support cabin service. The three-tier design maximizes carrying capacity so you can serve meals and beverages efficiently in a single cart, which helps crew work faster and keep meals accessible to passengers. The aircraft’s galley layout and aisle width are arranged to accommodate two of these carts, typically located in the forward galley so service can be conducted on both sides of the cabin without crowding the aisle. One cart would limit service capability, while three or more would exceed the galley footprint, so two is the practical, standard setup.
