AVIA101 Lecture Notes - Lecture 21: Crosswind, Wind Shear, Aileron
Document Summary
When you approach a downsloping runway it appears as though it is sloping away. If crosswind is 70 to 90 degrees assume no head wind component. Into-wind wing gets more airflow = more lift which makes the aircraft want to roll. Take advantage of aileron drag to keep from drifting. When speed increases, lessen the aileron deflection. Airplane will naturally crab into the wind: not sufficient if crosswinds are high, need aileron deflection to maintain straight path. Lower wing slightly into wind, apply more rudder. See where nose is pointing, if pointing left wind is from the left: apply right rudder and turn into wind slightly. Keep side-slip through flare, upwind wheel should touch down first. Best to use 10 degrees flaps (too much flap = more surface for wind to influence a/c) Need higher approach speed due to wind shear. Half of the gust factor and add to as.
