    RE: Crosswind landings

    Not to be picky, but ...

    A crab is straight flight into the wind. The plane apears to 'crab' sideways due to the cross wind. Plane is into the wind. It crabs on a ground reference down the runway.

    A forward or side slip involves application of rudder and opposite aileron. From reference in the cockpit, as you approach the runway, you apply downwind rudder to straighten out with reference to the runway. Opposite aileron (dipping the upwind wing) is necessary to avoid a yaw turn.

    From the ground, as the plane comes toward you (assuming on a correct line of approach) it has the nose crabbed into the wind until you kick in the rudder. The way I remember which way to push the rudder is to move the stick into the wind as I face the airplane. I apply rudder just before flair (timing is personal choice) and match that with opposite aileron.

    Important to remember that stall speed is higher when cross controlled and is lopsided. A sure way to enter a stall-spin. Deadly on approach.

    Us Cub flyers learn to use slips to eat up energy on approach when we are too high and fast.

    Have fun!
