"By the way side slip is when your airplane is not flying straight. It's flying sideway when you are trying to lose altitude. Forward slip is when your airplane is flying straight for example when you are doing a corss wind landing. Although you are using rudder your longitudinal axis of the airplane is aligned with the runway. Plus go by things your instructor tells you that way if the examiner finds you wrong you might just get to slide. Some times if you say something wrong and you can prove you were tought it wrong like this examiner will let you slide saying ok I'll tell you the right way and from now on go by my way. That happened to a friend of mine."


You've got it backwards, my friend. est of luck to both of you, I'll be taking my CFI initial in about 2 weeks.
