I was always taught the crabbed method and it has never been an issue the fact that I haven’t done the wing down method. Landed in a 12kt crosswind (club limits for PPL holders on club a/c) on Tuesday and the crabbed method worked great. Although, I wouldn’t have liked to have done it as a solo student. Even of there wasn’t a limit on club a/c landing in crosswinds, iv set my limit at 12 kts for the min, not much higher than that.
Said airport that I think the king is learning at though seems to always have a massive crosswind on landing. Its like the runway is just at right angles to the prevailing wind! Good cup of tea though in the tower
