|747-8 Freighter |
The first 747-8 Freighter at the fuel dock of Boeing Everett Plant, November 23, 2009The 747 has proven to be a very popular freighter, carrying around half of the world's air freight as of 2007[update]. In an effort to maintain this dominant position, Boeing designed a freight variant of the 747-8, named the 747-8 Freighter or 747-8F, which was launched on November 14, 2005. The 747-8F will be the initial model to see entry into service (EIS). As on the 747-400F, the upper deck is shorter than passenger models; the 18 feet 3½ inches (5.575 m) stretch is just before and just aft of the wing. With a 975,000 lb (442,000 kg) maximum take-off weight, it will have a total payload capability of 308,000 lb (140,000 kg) and a range of 4,390 nmi (8,130 km). Four extra pallet spaces will be created on the main deck, with either two extra containers and two extra pallets, or three extra pallets, on the lower deck.
The 747-8F is expected to achieve a 16% lower ton-mile operating cost than the 747-400F and offer a slightly greater range. The 747-8F will have more payload capacity but less range than the current 747-400ERF. When Boeing launched the -400ERF, all of the 35,000 lb (16,000 kg) increase in MTOW over the 747-400F 875,000–910,000 lb (397,000–410,000 kg) allowed airlines to take off with more fuel, burn it during flight, and land at the same weight as the regular 747-400F. This increased the range of the 747-400ERF compared to the 747-400F. Cargo carriers often move machinery or indivisible loads that require a plane with a higher payload and landing capability. As is common with cargo planes, range is given with maximum payload, not fuel. The 747-8's 65,000 lb (29,000 kg) MTOW increase has been directed exclusively to its Zero-Fuel weight or payload capacity. If taking off at maximum payload, the 747-8 takes off with its tanks not full. On trips where the payload is not at maximum, the plane can take on more fuel and extend its range.
