Wide-body Aircraft
A wide-body aircraft, also known as a twin-aisle aircraft and in the largest cases as a jumbo jet, is an airliner with a fuselage wide enough to accommodate two passenger aisles with seven or more seats abreast. The typical fuselage diameter is . In the typical wide-body economy cabin, passengers are seated seven to ten abreast, allowing a total capacity of 200 to 850 passengers. Seven-abreast aircraft typically seat 160 to 260 passengers, eight-abreast 250 to 380, nine- and ten-abreast 350 to 480. The largest wide-body aircraft are over wide, and can accommodate up to eleven passengers abreast in high-density configurations. By comparison, a typical narrow-body aircraft has a diameter of , with a single aisle, and seats between two and six people abreast. Wide-body aircraft were originally designed for a combination of efficiency and passenger comfort and to increase the amount of cargo space. However, airlines quickly gave in to economic factors, and reduced the extra passen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N26902@PEK (20181229152149)
N, or n, is the fourteenth Letter (alphabet), letter of the Latin alphabet, used in the English alphabet, modern English alphabet, the alphabets of other western European languages, and others worldwide. Its name in English is English alphabet#Letter names, ''en'' (pronounced ), plural ''ens''. History One of the most common Egyptian hieroglyphs, hieroglyphs, snake, was used in Egyptian language, Egyptian writing to stand for a sound like the English , because the Egyptian word for "snake" was ''djet''. It is speculated by some, such as archeologist Douglas Petrovich, that Semitic languages, Semitic speakers working in Egypt adapted hieroglyphs to create the first alphabet. Some hold that they used the same snake symbol to represent N, with a great proponent of this theory being Alan Gardiner, because their word for "snake" may have begun with n (an example of a possible word being ''nahash''). However, this theory has become disputed. The name for the letter in the Phoe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
