The aircraft model is based on the German Lufthansa Airlines A340-600 alloy 1:470 aircraft as the prototype, and is produced according to the actual size of the aircraft by scaling-down (1:437). The fuselage and bracket are made of zinc alloy die casting, the base is made of transparent plastic, which is strictly controlled by experienced technicians during the production process. The craft is fine and the image is vivid, and it is a fine product of the same kind!

The fuselage of the Airbus A340-600 is more than 10 meters longer than that of the-300 model. A340-600 is the longest airliner in history. The length of the Bibo sound 747-400 is 4 meters, it is even 2.3 meters longer than Airbus's new super-large long-distance wide-bodied (airliner) A380, which is why A340-600 has the title of "French big stick. Four Trent 556 engines with a pushing force of 249 thousand Newton are adopted, and there is also a set of main landing gear composed of four wheels at the center bottom of the fuselage, which is used to bear the increased maximum takeoff weight (MTOW). At first, seven delivered A340-600 wings were too heavy, and the new planes had been revised. These planes with overweight wings were later sold to Cathay Pacific and Iberia at a lower price.
A340-600 designed to the early boeen 747 competition A340-600 in 3 ji cabin layout with a total of 380 passengers (level 2 cabin layout: 419) over more than 7,500 nautical miles (13,900 kilometers), A340-600 is powered by the turbofan engine of the Qida 500 model. The passenger capacity of this A340 ultra-long aircraft with 20 compartments (over A340-300) is similar to that of the sound 747, however, the pallet shipping capacity of the bilge is twice that of 747. The average travel and seat costs are lower than those of sound 747. A340-600 Boeing passenger planes of the same type are sound 777-300ER.
The "Higher Gross Weight" model of Airbus A340-600, named A340-600HGW. Its maximum takeoff weight (MTOW) is 380 metric tons, and its endurance capacity is 7,900 nautical miles (14,600 kilometers). The-600HGW model can achieve the above performance because of its enhanced structure and increased fuel carrying capacity. Trent 560 engine is used to replace the original Trent 556, each unit provides an additional 4000 pounds of thrust and new manufacturing technologies such as laser beam welding. The first A340-600HGW was first tested on November 18, 2005 and delivered to Qatar Airways at the end of 2006.
Airbus had previously issued a warning that the A340-600 aircraft was overweight due to improper design of the front and middle parts, which may pose a threat to flight safety. Airbus pointed out that the reason for the heavy weight may be that heavy furniture and entertainment systems were installed in the first class, which led to the head down of the plane's flight timing, which not only did not conform to the aerodynamic principle, and may bring danger to passengers and crew, and when the plane flies again, the front low and rear high will also increase the wing resistance, thus affecting the fuel consumption. The solution of Airbus is to reduce the loading of 5 tons of cargo in the front cargo compartment of the aircraft.
