On April 8th, 104 test aircrafts of the ARJ21-700 aircraft independently developed by China went to Iceland, "away home" for 41 days, and after more than 20,000 kilometers of voyages, they landed smoothly at Xi'an Yanliang Airport and slowly greeted them. The "Watergate", the European Icelandic cross-wind test flight draws a full stop. On March 26, China Civil Aviation Administration test pilot Zhao Zhiqiang and China Aviation Industry Corporation test flight center test pilot Chen Ming drove six takeoffs and six landings at the Keflavik International Airport in Iceland with the ARJ21 aircraft 104. The data shows that during the take-off phase, the maximum instantaneous wind speed of the crosswind is 47.4 knots (about 87.78 km / h, equivalent to 9 gale), the average wind speed is 38.4 knots (about 71.11 km / h, equivalent to 8 winds); in the landing phase The maximum instantaneous wind speed is 48.7 knots (about 90.19 km / h, equivalent to 10 winds), and the average wind speed is 35.2 knots (about 65.19 km / h, which is equivalent to 8 winds). The anti-crosswind capability is a very important feature of the aircraft. Strong crosswinds can seriously affect the take-off and landing of the aircraft. The safe take-off and landing of the aircraft under large cross-wind meteorological conditions must be verified by test flight test. As the first jet airliner to be put into commercial operation in China, the ARJ21-700 aircraft obtained the type certificate on December 30, 2014, the first flight on June 28, 2016, and the production license in September 2017, officially entered into mass production delivery. stage. There are 21 domestic and foreign customers and 453 orders. The completion of the target task of the large crosswind test flight cleared the obstacles for the ARJ21 aircraft to further expand the market and expand the scope of operations.
