   China's first domestically-developed heavy transport aircraft, the Y-20, successfully took off for its first test flight on January 26. Now, Y-20's trial flight has entered a new phase. Our reporter Li Dong has the details.


 
  Different from the previous yellow-green paint, the new Y-20 has been repainted a dark gray, signifying that the aircraft's trials have entered a new phase.
 
  The large and multi-functional transport aircraft can carry out long-range transportation missions even under difficult weather conditions.
 
  Tang Jun, chief commander of Y-20 research project says the aircraft is a big step forward for China's aviation industry.
 
  "The successful first flight of the Y-20 indicates the gap between China and American and European transporters is shortening. In some areas, we are even at the same level with those countries who manufacture such transporters."
 
  Guo Zhaodian, deputy chief designer of China aviation industry heavy transport aircraft says the designs of many parts of the Y-20 were self developed.
 
  "The design of the wings is the most complicated and advanced part in terms of aerodynamics. We can see that Y-20 has leading edge slat and trailing edge flap. These are designed to provide enough lift for such a heavy transporter, so the take off and landing distances can be shortened."
 
  One of the most important features of the Y-20 is the carrying capability 2 which reaches over 100 tons. It can be used for military operations, disaster relief and rescue work.
 
  Du Wenlong, a military commentator 3, says the ability to develop such a heavy transport aircraft is a demonstration 4 of a country's comprehensive power, from its economy to its technology.
 
  "I think one of the difficulties is the dynamics 1 system. It requires high propulsion and low fuel consumption. The engine technology is a key technology. It's hard to develop totally relying on your own capability."
 
  "Another difficulty is the trunk of the aircraft. Because the weight heavy transporters are required to carry is way more than ordinary flights, it's very demanding on the material used in building the plane, as well as the cabin design."
 
  "So the heavy transporter can transport large scale cargo 5, machines and equipment. Plus, the safety design is very demanding, because fighter jet pilots can eject and parachute when there is emergency situation. Big planes don't have such safety measures. So the heavy transporters need to be very safe for pilots. That's why many countries can manufacture fighter jets but they can't build heavy transporters."
 
  The Y-20 was developed by Xi'an Aircraft Industry Group, a subsidiary of China's leading military aircraft maker 6, the Aviation Industry Corporation of China.
 
  The Y-20 project was initiated 7 in 2007. It only took 5 years to turn it from draft on paper into the real transporter.
