4.4. Crosswind Takeoff. The procedures for a takeoff with a crosswind are the same as for a no- wind takeoff except aileron is held into the wind to keep the wings level. Aileron deflection is necessary because the upwind wing develops more lift, causing it to fly (begin rising) before the downwind wing. If the upwind wing rises, skipping may result (Figure 4.2.). Skipping is a series of very small bounces caused when the aircraft attempts to fly on one wing and settles back onto the runway. During these bounces, the aircraft moves sideways and increases stress on the landing gear. Pilots should anticipate aileron requirements due to the crosswind and either pre-position aileron into the wind or apply aileron into wind as required during takeoff roll. Use rudder to keep the aircraft pointed straight down the runway and to prevent the aircraft from “weathervaning” (i.e., “crabbing” or turning into the wind). The flight controls become more effective as airspeed increases, so progressively smaller control inputs are required to maintain aircraft control.
