A crosswind is any wind that has a perpendicular component to the line or direction of travel. 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 may exceed an aircraft's crosswind limit, and an attempt to land under such conditions could cause structural damage to the aircraft's undercarriage. Crosswind is sometimes abbreviated as X/WIND.Operations in crosswind conditions require strict adherence to applicable crosswind
limitations or maximum recommended crosswind values , operational recommendations
and handling techniques, particularly when operating on wet or contaminated runways.
Adverse wind conditions (i.e., strong crosswinds, tail winds and wind shear) are
involved in 33 % of approach-and-landing accidents.
Crosswind in association with runway condition is a circumstantial factor in nearly 70 %
of runway excursion events.
85 % of crosswind incidents and accidents occur at landing.

Some landing and take-off highlights in awkward wind conditions at BHX (a record winter for stormy conditions in the UK). Note the frequent flexing of the planes' wings in response to the turbulence.
Of the five "missed approaches" shown, three diverted to other airports, two were "go arounds" and landed successfully on second attempt.
