Basically, there are two techniques; kick off drift and wing-down. The aircraft configuration and control characteristics usually determine which method is favored. As wing-down involves bank, then low wing / pod engine configurations tend to avoid it. Manufacturers usually recommend the appropriate method – follow the manufacture’s advice.
Gerund I fear that you are grossly mistaken. Although the common understanding of ‘demonstrated crosswind’ is not limiting, in many aircraft, it can be, and is published as such.
When a limit is reached, it comes very quickly, +/- 1 kt. Also remember that the limit is based on an average pilot not requiring unusual skill etc. Assuming that everyone will class themselves equal too or better than that, then what happens to everyone else – it’s probably all of us on a bad day, night time, wet, tired and wanting to get home. The limiting component of the crosswind limit in many accidents is human performance.
Remember that that most aircraft require increasing rudder as speed decreases – fly the aircraft when on the ground by applying more rudder if required. For those aircraft without nosewheel steering or unavailability just after touch down, rudder may be the only control that is available as aileron does not work on all aircraft. You may need the entire rudder defection just to stay on course, but what if the course has already deviated towards the edge, where is the extra rudder coming from … then there is reverse which may not help. Beware the reported wind – it is far from the truth.
For background and further explanation of the points above see
‘Safety aspects of aircraft operations in crosswind’; read this in conjunction with ‘Safety aspects of aircraft performance on wet and contaminated runways’
I suggest that everyone should include in his or her crosswind landing check an item which asks ‘should we be doing this?’ – not can we do it.
