The description of the large cross wind landing crossover and the root description of the large cross wind landing crossover, as well as the description of the FCTM manual on events requiring maintenance Appendix A.2.1, the following statements are correct.
A.The risk of veer-off is high when landing with cross-grounding in high cross winds, or when there is a deviation in the directional position when grounding, if the rudder is not used properly, superimposed on the length characteristics of the B787 fuselage, which will lead to a large lateral overload. B.For dry runways with significant cross wind conditions, the "uncrossing method (uncrossing before grounding)" is the recommended landing technique. C.When stirring the rudder, the upwind wing will move to the downwind side to produce a cross roll. It is necessary to keep the wing level by going up the wind pressure plate at the same time. This type of grounding uses a crossover maneuvering method, where the left and right main wheels are grounded simultaneously. During the whole grounding process, the upwind pressure plate is used to keep the wing level. D.All of the above正确答案D
