Boeing's 747-300 model presented the unique extended upper deck which can seat up to 69 economy class travelers.
The 747-300 was the deciding aftereffect of various Boeing studies which took a gander at expanding the airplane's seating limit. Thoughts concentrated on included fuselage plugs fore and toward the back of the wing expanding seating to around 600, or running the upper deck down the whole length of the fuselage. At last Boeing propelled the more humble 747sud (Stretched Upper Deck) with more noteworthy upper deck seating on June 12 1980.
The 747sud assignment was soon changed to 747eud (for Extended Upper Deck), and after that 747-300. The new model first flew on October 5 1982 and was initially conveyed to Swissair on March 28 1983. Different clients included UTA, Saudia, SIA, Qantas and Cathay.
Contrasted with the -200, the -300's upper deck is extended toward the back by 7.11m (23ft 4in), expanding economy class seating from 32 to a most extreme of 69. The extended upper deck presented two new crisis retreat entryways and permits a discretionary flightcrew rest region promptly rearward of the flightdeck to be fitted. Access is by means of a traditional instead of winding staircase as on the prior models.
Generally the 747-300 is basically minimal transformed from the 747-200 and gimmicks the same takeoff weight and motor choices. 747-300 variations incorporate the 747-300m Combi and the short go 747-300sr constructed for Japan Air Lines for household Japanese administrations.
The developed upper deck was additionally offered as a retrofit to existing 747-100/ -200s, despite the fact that the main aerial transports to take up this alternative were KLM and UTA. KLM has since changed over two to vessels, bringing about the initial 747 tankers with the extended upper deck. Additionally, two JAL 747-100s were conveyed new with the augmented upper deck.
