The following guidelines are advised by Boeing for a crosswind landing. These guidelines assume steady wind (no gusting). These winds are measured at 10 metres (33 ft) tower height for a runway 45 metres (148 ft) in width. Basically, there are three landing techniques which may be used to correct for cross winds: de-crab, crab, and sideslip.
A flight path parallel to and in the direction of the landing runway. It is offset from the runway and opposite the downwind leg. Crosswind leg. A short climbing flight path at right angles to the departure end of the runway. Downwind leg. A long level flight path parallel to but in the opposite direction of the landing runway.
The sideslip method for crosswind landings is not suitable for long-winged and low-sitting aircraft such as gliders, where instead a crab angle (heading into the wind) is maintained until a moment before touchdown. Aircraft manufacturer Airbus recommends sideslip approach only in low crosswind conditions. [7]

For example, a 10 knot wind coming at 45 degrees from either side will have a crosswind component of 10 knots × sin(45°) and a head/tailwind component of 10 knots × cos(45°), both equals to 7.07 knots. Pilots can use a use a crosswind component chart to calculate the headwind component and the crosswind component.
Crosswind landings - where a significant wind not aligned with the landing area is a factor [4] Short field landings - where the length of the landing area is a limiting factor [ 4 ] Soft and unprepared field landings - where the landing area is wet, soft or has ground obstacles such as furrows or ruts to contend with [ 4 ]
So the analysis would be applied, for example, assuming: Straight and level flight Turn at constant speed Approach and landing Takeoff. The speed, height and trim angle of attack are different for each flight condition, in addition, the aircraft will be configured differently, e.g. at low speed flaps may be deployed and the undercarriage may be ...
