Aircraft Crosswind Landings & Take-offs Video
In situations where a crosswind is present, the aircraft will drift laterally as it approaches the runway. If the crosswind landing is not executed safely, the aircraft may experience wingstrike, where a wing hits the runway. The following guidelines are advised by Boeing for a crosswind landing. Basically, there are 3 landing techniques which may be used to correct for cross winds: de-crab, crab, and sideslip. De-crab: The objective of this technique is to maintain wings level and the aircraft position near the runway centerline during approach. Crab: The airplane can land using crab only (zero side slip) up to the landing crosswind guideline . Side_slip: This sideslip crosswind technique is to maintain the aircraft's heading aligned with the runway centerline. The technique used during the initial takeoff roll in a crosswind is generally the same as used in a normal takeoff, except that the aileron control must be held INTO the crosswind. This raises the aileron on the upwind wing to impose a downward force on the wing to counteract the lifting force of the crosswind, and prevents that wing from rising. Video is 11 mins long but well worth a look. The airport is Birmingham (BHX), UK. Note the flexing of the wings, especially during take-offs. http://avstop.com/ |
