跑道。但倘若转得太晚，飞机的起落架在接触地面时仍没有对齐跑道，可能会因而损坏或折断，严重时可以导致飞机撞毁。就算飞机师是在适当的时间扭转机头，飞机在蟹形角度减少之后会短时间随风向侧飞，令起落架无可避免需要吸收一定侧向的负载。
记得以前教科书上说，修正侧风有两种办法，通俗的讲就是蹬舵或者侧倾单轮着陆，客机进近的时候如果以为的侧倾，比较难掌握降落的横向位置和乘客会感到不安，所以一般采用蹬舵，所以机身与跑道成的夹角很大，但是进近的最后阶段，接地的时候，因为重型客机像777、744，靠稍微的侧倾就可以修正侧风了，所以飞行员一般就在最后一霎那让机轮单侧着地，但是机头与磁航向基本保持一致.
Airliner landing technique
Did you ever intentionally land with the crab angle intact?
It's a fact F16 can be crab landed with a max crosswind of 25 knots.
An F-16 is a very different beast than an air transport jet.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Here's an explanation by a highly qualified (F-4G, F-16, and B-52) USAF
pilot:
'
have the wings level through touchdown, the landing 'trucks' aligned
with the runway, and the aircraft fuselage crabbed in to the wind.
and, using a handy 'crosswind landing chart,' computes the number of
degrees that the landing 'trucks' must be offset to ensure they are
aligned down the runway on landing. Then the pilot or copilot reaches
down to a mechanism sitting between the pilots and 'dials in' the
appropriate number of degrees of offset for the trucks. This procedure
is accomplished for EVERY landing.
for 20 degrees of offset. More offset is possible but slightly
uncomfortable for the new pilot making such a
looking straight ahead at touchdown but rather he will be looking toward
his left or right shoulder.'

downwind rudder, surely.

Correct, downwind rudder and upwind aileron.
wind is from 360 at 25, the left foot will be on the rudder and the control wheel
will be to the right. ;-)
