According to Airbus's convention, the name of the new passenger plane should be A350. However, according to Airbus, after a thousand years and entering the new century, Airbus also needs a big leap in technology, so it should be named A360 to cross A350. However, A360 means to turn a circle in British aviation language, and Airbus certainly doesn't want to just turn a circle. Next should be A370. However, in Airbus's eyes, 7 has a symbolic connection with competitor Boeing. Boeing's aircraft starts with 7, and then "8" is a well-known auspicious number in Asia, especially in Greater China, so this future passenger plane is named A380. A380(Airbus A380 is the world's largest wide-body passenger plane manufactured by Airbus Europe, and is known as the "Big Mac in the Air". It is the passenger plane with the highest capacity in the world [1] and the first real double-deck passenger plane in the aviation industry, that is, it has a double-deck cabin from beginning to end. The aircraft uses more composite materials, which improves aerodynamic performance, reduces the weight of the aircraft, reduces fuel consumption and emissions, and reduces operating costs. Airbus A380 completed its first flight on April 27th, 2005 and put into use on October 25th, 2007.
