Well use a 20-knot wind. Statistical evidence, based on historic accident data, shows that the accident risk increases exponentially when operating in conditions with crosswind exceeding 20 Kt, including gust. register a celtic supporters club. During the final approach to land, the tower reported the wind as gusting up to 47 kt, and the aircraft continued the approach. These are the steps to use a crosswind chart: Find the line that represents the angle between your direction and wind direction. By the end of this article, it will all make sense. Many pilots think it is an actual [real-time] measurement; it is not. To find the crosswind component, you need to multiply wind speed by the sine of the angle between wind direction and the direction you're facing: crosswind speed = wind speed sin () In this text, is the angle of the wind from the direction of travel. History shows most loss of directional control during landing crashes occur with less than 10 knots crosswind component. By learning to make a crosswind estimate early on, student pilots will be better positioned to decide on the best runway to use.
