Do you crab or forward slip in X wind landings
Do you crab or forward slip landing in x-winds and why? When I was taught how to fly an airplane the crab method was used when I transitioned to gliders my instructor emphasized forward slip over crab. Years later I have established my procedures, but I thought this might be a useful discussion for newer pilots.

Standard UK training, at least when I learnt and I haven't heard any different from our instructors since, is to crab with wings level on approach and kick the glider straight just before touchdown. Another point is that we are taught to do fully held-off landings regardless of the size and surface of the club field on the grounds that its the only sensible way to land out, so we should be able to do it well. I think the two are related because this keeps the wings level while speed bleeds off and its fairly easy to kick the glider straight as it settles. If you also manage a neat two-pointer you can award yourself brownie points as well as knowing that this will help to keep the glider running straight despite any cross-wind. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

One comment on the crab method, you must transition to forward slip before touchdown. What if when you if you go to kick out the crab, just above runway and you find out that the x-wind is too strong for a forward slip to maintain track.

If I do the crab+held-off landing properly, I should be under 3 ft up (at the very most: half that is better) and already sinking when I kick the glider straight. If you're too early straightening up, of course you're being blown sideways when you land. AFAIK the upwind wing low technique you guys call 'forward slip' isn't taught to UK glider pilots. I was never taught it and can't recall seeing anybody using it on our field. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

Wouldn't that be a "side slip" since the glider's fuselage is aligned with the runway (hopefully) while the windward wing is a little low? |

I have found over the years that students have a much easier time dealing with cross wind using the slip method. The aiming point does not change. They look right over the nose as usual. They do not have to try to kick out a crab and move to a wing low attitude while trying to time the round out to a low energy landing. Obviously they nee to be aware of their bank angle near the ground but the reduced drift down low seems to take care of that. UH |

I tend to use slip as you can keep lined up on the approach and it is easy to adjust the slip for wind shear. |
