It is not possible to give a defintive approach as all airports are different however, if possible have a long as possible final to establish the real crosswind and crab into it. This will change as you lower and on the ground. Keep crabbing all the way down with the centre line extending to between your legs this does bring you right down in the middle. Bring the plane down and flare like this, just before touch down opposit rudder to bring straight, it does work very well as I have been given students that other instructors were having trouble with and two lessons sorted. The first being the low app and go round. Its all about staying calm and making sure that the student is always enjoying what they are doing even if it is hard work.
