SIDESLIP - A movement of an aircraft in which a relative flow of air moves along the lateral axis, resulting in a sideways movement from a projected flight path, especially a downward slip toward the inside of a banked turn.
Sideslip: The deliberate or involuntary movement of an aeroplane downwards and outwards from its true course. A stable type with adequate keel surface will right itself.

Sideslip to a crosswind landing
In a sideslip to a crosswind landing the aircraft is always banked with the into-wind wing down so that the sideslip can be smoothly decreased to a forward slip [see below] before the roundout.
Wing down / sideslip
The wing down/slip method requires the pilot to fly the aircraft lined up with the runway and banked into the wind when turning on final, at this point the aircraft slips and consequently stall speed is higher.
Fig. 2: Non-zero sideslip sets the lower, upwind wing to a higher angle of attack, resulting in stabilising roll moment P.
The aircraft is shown flying towards the viewer.
The potentiometers for measuring the angle of attack and angle of sideslip are mounted in a common boom fitted on the right wing tip. The wiper arm of the potentiometer is directly connected to the vane.
If the aircraft has a right wing pushed down, the positive sideslip angle corrects the wing laterally before the nose is realigned with the relative wind.
If you’re using a sideslip during crosswind landings (as I suspect you are), this increases drag which helps counteract the floating caused by excessive airspeed.
Some aerodynamics texts use the term sideslip angle, which is synonymous with slip angle.
maneuver in which a significant component of the prevailing wind is perpendicular to the runway centerline. The three most popular and widely utilized crosswind techniques that are used to correct for cross winds are: De-Crab, Crab, and Sideslip.
