Which statement about the 787-9's 3-tiered carts is correct?

• A. The 787-9 has 0 carts
• B. The 787-9 has 1 cart
• C. The 787-9 has 2 carts
• D. The 787-9 has 3 carts

Answer: (B)

Understanding how many 3-tiered service carts the 787-9 uses helps you answer quickly. The 3-tiered cart is a single three‑level trolley used in the galley for in‑flight service. In the standard 787-9 configuration described in the training materials, there is one of these carts installed per aircraft. That’s why the correct statement is that there is one cart. This design keeps service efficient with a single, compact unit for beverages and meals; claiming zero would ignore the galley equipment, while suggesting two or three carts would indicate more than the typical configuration for this model.
