OOHHH great, that clears it up. I've done a sideslip, looks like the forwardslip is for REALLY bad crosswinds.
Think of it this way: the term "slip"indicates the plane is not going entirely nose-first into the relative wind ( I know it's not that simple, but you get my meaning?). So now to describe slipping along one's ground track (the runway centerline), with the low wing leading the way, the term "forward slip" makes some sense. Likewise, to describe slipping across one's track, just quickly enough to compensate for wind blowing across that track, the term "sideslip" is more appropriate. Anyway, that's how I clarified it for myself; I needed to do that, 'cause these maneuvers are two very different animals! I guess you could call them the "sideslip" and the "forward sideslip"...Thanks Rotty. I suspected as much but, being old-fashioned, a forward slip is still a sideslip to me.
Doesn't surprise me... reminds me of the US/UK discrepancy between "angle of attack" and "angle of incidence". Let's face it, you people talk funny. ;) Doesn't matter, as your introduction to slips was probably more practical ("sideslip this way, or this way"...). Probably for the best, 'cuz a demonstration is worth a thousand words... but it's odd that you've never seen the term "forward slip" in a book; I own a few that mention it by that name, i.e. the USDOT manual shown above. Maybe it's a relatively new distinction in books...I've been interested in aviation since I was 6 years old & read many books on the subject over the years. I got my gliding licence when I was 16 & my first job (in 1960) was with a flying club. I've been in the aviation industry all my working life. This is the first time I've ever heard the expression.
He's right, beefy. And not only is it beautiful to watch, it's a joy to execute! Very handy sometimes- I've often done it to salvage a high approach, as well as for clearing obstacles.No Beefy. You have the wrong idea. Nothing to do with crosswinds. This "forward slip" is simply a different term for a sideslip used to lose excess altitude quickly on the approach, typically to get into small fields over high obstacles (like tall trees) on the boundary. When done properly by an experienced pilot it's beautiful to watch.
I've found the forward slip is much easier to execute without much crosswind... if your nose is pointed to the right into the wind and your downwind (left) wing is low, you may not be able to check that drift very well. As for yawing away from the crosswind: I've never tried it. With a good crosswind, I'll stick with a sideslip or a good ol' crab (coordinated turn into the wind) .There are other times it can come in handy but you can do it when there is no wind at all.
