The Side-Slip Technique
The Sideslip Technique differs from the Crab and De-Crab techniques when the wheels touch the runway. The upwind wheels touch first in the Sideslip.
When you start the sideslip, on your approach, you use the crab technique to correct for drift caused by the crosswind. The actual heading of the planes body, after drift correction, is controlled by using the rudder and ailerons to align with the runway center line.
If you keep the position of the rudder/aileron and apply pressure, the plane stays at a constant sideslip angle unless the crosswind changes velocity, like on a gusty wind day.
The plane tries to correct back, under these pressures and control applied by the pilot, to the aircraft's natural stability in straight and level flight.
The sideslip configuration creates a tendency for the wings to cause the plane to roll. This is referred to as the dihedral effect.You must apply aileron to check the bank angle.
When you make contact a small amount of bank angle is present that causes the upwind wheels to touch the runway first.
The danger,in this technique, is excessive control that may cause over-banking where damage occurs to the wing.
If the crosswind is strong and gusty it makes control of any of the techniques difficult. Flying on days where gusty conditions are present is dangerous.
A Instructor can help you learn when to fly or wait for a better day.
