Wind that faces opposite side of a plane when landing

A crosswind is any wind that has a perpendicular component to the line or direction of travel. This affects the aerodynamics of many forms of transport. Moving non parallel to the wind direction creates a crosswind component on the object and thus increasing the apparent wind on the object; such use of cross wind travel is used to advantage by sailing craft, kiteboarding craft, power kiting, etc. On the other side, crosswind moves the path of vehicles sideways and can be a hazard.

In aviation, a crosswind is the component of wind that is blowing across the runway, making landings and take offs more difficult than if the wind were blowing straight down the runway. If a crosswind is strong enough, it can damage an aircraft's undercarriage upon landing. Crosswinds, sometimes abbreviated as X/WIND, are reported in knots, abbreviated kt, and often use the plural form in expressions such as "with 40kt crosswinds". Smaller aircraft are often not limited by their ability to land in a crosswind, but may see their ability to taxi safely reduced. Crosswinds can also cause difficulty with ground vehicles traveling on wet or slippery roads (snow, ice, standing water, etc. ), especially when gusting conditions affect vehicles that have a large side area such as vans, SUVs, and tractor trailers. This can be dangerous for motorists because of the possible lift force created, causing the vehicle to lose traction or change direction of travel. The safest way for motorists to deal with crosswinds is by reducing their speed to reduce the effect of the lift force and to steer into the direction of the crosswind. Cyclists are also significantly affected by crosswinds. Saving energy by avoiding riding in wind is a major part of the tactics of road bicycle racing, and this particularly applies in crosswinds. In crosswinds, groups of cyclists form 'echelons', rotating from the windward and leeward side. Riders who fail to form part of an echelon will have to work much harder, and can be dropped by the group that they are with. or flat stages of the Tour de France.
