I am a low hour rec pilot, got about 150 hours up now. Just about to do the PPL test.
One thing I realiased about crosswind landings is that if you slip it in, you are dragging it in under power. I was doing some training with an instructor in less that ideal conditions once, low vis, crosswind etc. I had this mental block, and kept using the rudder to keep me aligned with the runway but could not understand why I had to keep feeding in the power to keep the approach angle and speed where it should be.
I dont know what the best way to approcah a crosswind is, but I have had it hammered into me to keep a tight circuit and not drag the plane in under power. Not sure how many engine failures you get on final, but that was the excuse for that style of training. I can say from my limited experience that crabbing in and using rudder just before touch down certainly requires the least amount of power. This is now my preferred technique. Is it right or wrong? I dont know, but it works for me.
