Do you own an older Boeing 747 and are looking to improve the way it looks? Does your upper deck just look so small compared to the 747-300, 747-400 and especially the 747-8I? Well, do not worry… Boeing has a deal for you: the 747 Stretched Upper Deck (SUD). Well, I guess Boeing had a deal for you, since they aren’t in the business of doing this anymore.
The SUD gave airlines operating older -100 and -200 747 models, the ability to stretch the upper deck and increase the number of passengers flown.Â When plane spotting, it is typically easy to tell the difference from a 747-100/200 and the 747-300 by check out the stretched upper deck, but the SUD makes it a bit more complicated.
From the image above: “The design of the Stretched Upper Deck option allows a 10 percent increase in capacity with only a 2 percent change in operating empty weight. This means added profitÂ potential, lower seat-mile costs and 5 percent lower fuelÂ consumptionÂ per available seat-mile.”
“This new option, available for the -100B/SR/-200B and -200B Combi models adds 280 inches of structure to the upper deck cabin.”
“The change is accomplished using current engine options and brake release gross weights of -100B/-200B models. Five maximum brake release gross weights are available ranging from the basic weight of 775,000 pounds (351 520 kg) to 833,000 pounds (377 780 kg). In addition to the basic JT9D-7AW, the -200B Stretched Upper Deck option is available with the following optional engines: Pratt & Whitney JT9D-JFW, -7J, -7Q and -7R4G2, General Electric CF6-50E/E1/E2 and Rolls-Royce RB211-524B2/C2/D4.”
“Weights and selected performance are presented on the following pages for only the 747-200B Stretched Upper Deck. 747-100B/SR and Combi performance is not shown.”
