Foreign business travelers have welfare! The aircraft is equipped with a time-lapse LED light

Curiosity Daily After four years of Boeing’s launch of the 787 Dreamliner, Airbus finally responded.

They recently delivered the first medium-sized aircraft A350 XWB to Qatar Airways, the successor to the A330 and A340, which you may see on domestic or nearby countries.

The design of the A350 XWB is bold and innovative, new materials, wings, space... but the biggest bright spot is that it wants to adjust the time difference with the lights. In fact, it is not a secret. The 16.7 million color LED lights in the machine can adjust the color temperature to mimic the sunlight, and the change is the same as the rhythm of your body, regardless of the time of the aircraft.

Other designs for the jet lag response include a venting system that changes every 2-3 minutes and stabilizes the cabin air pressure at an altitude of 1828 meters.

These designs may also be the reason why Qatar Airways is eager to order the A350 XWB, which currently travels across Europe, America and Asia with large jet lags.

The bold design of the A350 XWB doesn't stop there. Half of its structure uses carbon fiber, which is lighter than the aluminum used in aircraft today, making flight more economical.

As for the seat space of the economy class, it will be better. This is due to the wider fuselage of the aircraft, which is what its name means, XWB - Xtra Wide-Body.

At present, in addition to Qatar Airways, Vietnam Airlines, Finnair and other companies have placed orders for the A350 XWB.

The A350 XWB's biggest competitor, the Boeing 787 Dreamliner, was delivered in 2011. The fuselage also uses carbon fiber, and the design is also designed to improve ride comfort and flight economy. However, from 2007 to 2009, the Boeing 787 experienced no delays of five launches, which shows that these designs are not easy.

Can the A350 XWB help Airbus overtake Boeing? According to analysis by aviation consultancy Avitas, Boeing's total order volume in 2014 reached $115 billion, more than Airbus's $79 billion.
