Passengers don't tolerate slips well. Crab until you flare works in every airplane. On the B747 touchdown in the crab and let the friction of 16 tires swing the nose around. In most other airplanes, crosscontrol to make the gear trucks roll straight the runway.
You will learn what to do when you go to training on that particular type of aircraft. Get good landing a Cessna 172 in a crosswind and everything else will seem easy.
