China will deliver its first homemade C919 large passenger plane by the end of 2022,reported Xinhua.
   The plane,developed by the Commercial Aircraft Corporation of China(COMAC),gained the type certificate(TC) from the Civil Aviation Administration of China(CAAC) at the end of September.
   "The type certificate approval means the C919 has the 'certificate of entry' into the civil aviation market." Yang Zhenmei a senior CAAC official,told Xinhua.It also indicates that China has the ability to independently develop world-class large passenger aircraft,and marks an important milestone for the country's large aircraft industry.
   The C919 is a fourth-generation aircraft,which has a wingspan of nearly 36 meters,a length of about 39 meters and a tail height of around 12 meters.It has a layout of 158 to 168 seats.With a range of 4,075 to 5,555 kilometers,the C919 is able to fly between any two cities in China.So far,800 C919 aircraft have been ordered by 28 customers.
   Its aerodynamically - designed wings made from advanced metals and composites (復(fù)合材料) help improve fuel efficiency while reducing noise in the cabin .Its cockpit (駕駛艙)with the latest navigation technology and the so-called "fly by wire" computer controls,makes the C919 competitive with other narrow-body jets.
   Wu Guanghui,the chief designer of the C919,said he believes China will need around 2,000 narrow-body jets like the C919 in the future. "It will take up more than 70 percent of the commercial aircraft in China's civil aviation industry.We decided to make this kind of plane because it's the most in-demand product in the market." said Wu.

       Animals have been killed for their fur and feathers,for food,for sport,and simply because they were in the way.Thousands of kinds of animals have disappeared from the earth forever.Hundreds more are on the danger list today.About 170 kinds in the United States alone are considered in danger.
