In a ditching, how will the 777 most likely settle in the water?

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

Answer: (A)

When a ditching occurs, where buoyancy sits relative to the aircraft’s weight distribution determines the pitch once the airplane is floating. The 777’s flotation features and how buoyant forces act on the fuselage place more buoyant force toward the forward portion, while the tail remains relatively heavier and settles lower. That combination causes the nose to rise slightly as the airplane comes to rest on the surface, so it sits with a gentle nose-up attitude. This position helps keep the forward doors and cabin area above water and aligns the life-raft/slide systems for an orderly evacuation.
