BCpilot - actually you are correct, I also have a Canadian CPL, I flew floatplane charters in BC last year.
I always think that the definition in the FTM is the wrong way round logically but it is right as you are slipping in a forward direction in a forward slip - Thanks
I just find it easier to think of it that way round, if I am looking out of the side of the aircraft I am going sideways, If I am looking over the nose I am going forward
