Harry,

When you have a strong crosswind it is in effect a headwind. A headwind will slow your ground track and also make reduce your power off glide distance. To counteract that effect you have to use more power to compensate for the "headwind." This is no different than using more throttle to control your descent whne you have wind right down the runway.

As for the wing being blown over it is not a wind gust that is doing that. When you use the rudder to bring track the nose around it also causes a rolling action. This is especially bad with a high wing trainer. Take the airplane up in the sim and use the rudder only to make a turn. What you will see is the tail move firstthen the out side wing will rise. To stop the turn use opposite rudder and the inside wing will com back up. This is how you fly a 3 channel aircraft on rudder. Now that is not the proper way to do a turn but is good for demonstrating why the ing will rise when straightening out in a cross wind.

Once the wing starts to rise the crosswind can get underneath it and compound the propblem. if you watch closely in my sim video you can see me use some opposite aileron right before I touch down. The reason I do that is to keep the wing from rising and flipping the plane over. This also keeps the plane from drifiting off the runway.
