How does the 787 sit in the water?

• A. Nose slightly high
• B. Nose level
• C. Nose down
• D. Tail low

Answer: (A)

When a large airliner sits in water, it trims at the balance point between buoyancy and gravity. The way the 787 is built—the fuselage shape, weight distribution, and where the engines and tail add mass—causes the floating configuration to settle with the nose slightly higher than the tail. This nose-up attitude helps keep the forward fuselage and cockpit above water and reduces spray or water ingress into sensitive areas. A nose level or nose-down orientation would imply a different balance and isn’t how the aircraft tends to float in calm water.
