Um, yeah, well, OK so my ASI is 10 mph fast. The point is that we touch down a bunch faster than the little tail draggers at full stall. That lets us handle a much higher cross wind. Nag nag.

Yes, I did come down final at 80 indicated before I got my faulty ASI replaced. Afterward, with an ASI that checked out to within a mph or two to actual speed, 70 was a better number and my actual touchdown was right close to 50. And yet, the Coupe handles 25+ mph crosswinds just fine in spite of that terrible, low touchdown speed.

It is the fact that the bird comes over the fence at 80 mph and lands not a lot slower. This, mathematically speaking, decreases the crosswind component vector effect on the Coupe side travel. In other words, over a given distance of travel, a 25 knot crosswind has half less effect on a bird traveling 80 mph that is does on a bird traveling 40 mph. Straight vector analysis. This can have a major impact on touchdown. The added benefit of slip sill not really contribute much. Dave W
