Estimate from the variant's published specs, 0-5; scores are only comparable within one criteria year. Variant: 747-8 Freighter (GEnx-2B67, MTOW about 987,000 lb). Range 2.5 from 4,265 nmi with maximum structural payload (Wikipedia 747-8; freighter basis). Speed 4 from Mach 0.845 (ACAPS 747-8 Rev E). Runway 2 from the ACAPS sea-level standard-day takeoff graph at about 975,000-987,000 lb, read as about 10,000 ft. Capacity and comfort null (freighter); efficiency null: no fuel-burn figure published.[5]
The airplane performed as expected and handled just like a 747-400.
The 747-8 is one terrific airplane to fly, equal to the triple seven, if not even now my favorite, at least for some missions.
When we built the 747-8, we dialed it in to fly like the models before it as well.
