While it is usually preferable to take off directly into the wind whenever possible or practical, there will be many instances when circumstances or wisdom will indicate otherwise. Consequently, the pilot must be familiar with the principles and techniques involved in crosswind takeoffs as well as those for normal takeoffs. A crosswind will affect the airplane during takeoff much as it does in taxiing. With this in mind, it can be seen that the technique for crosswind correction during takeoffs closely parallels the crosswind correction techniques used in taxiing, previously explained in this handbook. Additional discussions of crosswind factors are contained in Chapter 9.
