Twenty-eight years ago today, on August 13, 1997 (July 11, 1997 lunar calendar), the first test flight of the Airbus A330-200 passenger aircraft was successful. The first test flight of the A330-200 long-range passenger aircraft developed by the European Airbus Group was successful on the 13th in Toulouse, southern France. The new passenger aircraft took off at 11:30 am and flew for a total of 4 hours. During the test flight, the Airbus Group used telemetry technology for the first time, transmitting data to the ground through the instruments carried on the aircraft, so that the test flight results can be analyzed and processed as soon as possible. The test flight of the A330-200 will continue until the end of next year, and six aircraft of this type will be used before and after. The A330-200 is a new member of the Airbus A330/340 long-range airliner family and the smallest model. It has a maximum range of 11,800 kilometers. It is reported that 49 orders have been placed for the A330-200 airliner. It accounts for 40% of the market share of commercial aircraft in this class.
