Estimate from the variant's published specs, 0-5; scores are only comparable within one criteria year. Variant: 747-400 passenger, MTOW 875,000 lb. Range 4.5 from 7,285 nmi with 416 passengers (Wikipedia 747-400). Capacity 5 from Boeing's airport-planning typical 400 seats in three classes. Speed 4 from Mach 0.85 cruise (ACAPS 747-400 Rev F, payload-range charts). Runway 1.5 from the ACAPS sea-level standard-day takeoff graph (CF6-80C2B1) at 875,000 lb, read as about 10,400 ft. Efficiency null: no fuel-burn figure. Comfort null: the reviews found are pilot handling reports, not passenger-cabin reviews.[4]
The 747-400 is a gentle giant. It flew like a dream, and was light on the controls.
the control surfaces are large enough and well boosted to provide very positive control feel in all phases of flight. It feels no more "truck-like" than any other transport category airplane I've flown.
pilots who have flown the 747 relate that she's a gentle giant, with relatively benign handling characteristics at low speeds, as well as surprising maneuverability for an aircraft with such mass and such a long wingspan
