Don’t worry; it will “click.”

Try to break your crosswind landing technique into smaller components:

a) Use rudder to align the longitudinal axis with the runway centerline.

b) Use aileron to lower the wing to control drift.

c) Flare normally.

Practice on narrow runways to hone your drift control.

Practice on long, long, wide runways to get the sight picture. I used to take students to a 12,000 foot military runway to practice slow flight at 3 feet agl.

You’ll get it. Good luck!
