在侧风风速超过55公里每小时的条件下，试飞员驾驶着ARJ21-700飞机104架机在冰岛凯夫拉维克国际机场执行了6个起飞和6个着陆。该机场的两条交叉走向的跑道提供了适合侧风试验的环境。
Test pilots performed six pairs of takeoffs and landings with crosswind speeds of over 55 kilometers per hour at the Keflavik Airport in Iceland, where two intersecting runways generate a suitable crosswind test environment.
对于飞机来说，抗侧风能力是很重要的，因为强侧风可能会影响它的起飞和降落。
It is important for an aircraft type to counter winds from the side, as strong crosswinds may affect its takeoffs and landings.
