Foreign business people have benefits. The aircraft was equipped with a time difference LED lamp.

After four years of curiosity launched by Boeing, 787 airplanes finally responded.

They delivered the first medium-sized aircraft A350 XWB to Qatar Airlines recently. They are the successor models of A330 and A340. You may see them in domestic or near National flights.

The design of A350 XWB is bold and novel, new materials, wings, space, but the biggest bright spot is that it wants to adjust the jet lag through the light. In fact, it is not a secret. The 16 million 700 thousand color LED lamp in its machine can adjust the color temperature to imitate the sunlight, which is the same as the circadian rhythm of your body, but has nothing to do with the time of the plane.

Other designs to combat jet lag include changing the air exchange system every 2-3 minutes and stabilizing the cabin pressure at 1828 meters above sea level.

Airbus A350 XWB's wing rises at the rear of the Airbus A350 XWB wing.

These designs may also be the reason why Qatar Airlines urgently ordered A350 XWB. The company's current routes span the larger difference between Europe and America and Asia.

The bold design of A350 XWB is more than that. Half of its structure is made of carbon fibers, lighter than the commonly used aluminum materials currently used by aircraft, making the flight more economical.

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

At present, besides Qatar Airlines, Vietnam Airlines, Finland airlines and other companies have placed orders for A350 XWB.

The biggest competitor of A350 XWB, the Boeing 787 Dreamliner, was delivered in 2011. The fuselage also uses carbon fiber, which is designed to improve ride comfort and flight economy. But in the past 2007-2009 years, Boeing 787 has experienced more than five delayed releases.

Can A350 XWB help Airbus anti super Boeing? According to the analysis of aviation consultant Avitas, Boeing's total orders in 2014 reached US $115 billion, more than 79 billion of Airbus.
