Agree 73qanda, the why is the training system that considers a cross wind landing a risk to the operation. On the Airbus it is also spreading to the use of manual thrust for landing where most pilots are actually apprehensive to turn the thing off. Certain aspects of flying require constant practice to a) get good at it in the first place and b) maintain that skill. It works for the training system to teach new pilots to fly by sim numbers. The assumption must be that by the time you reach the LHS you have attained the necessary skill through meditation and the ways of the Jedi.
