Except that the other bits you talk about are calculated, tested and verified.
I doubt that every sailplane type is deliberately ditched with wheel
up and down to see what happens. The Flight manual advice seems to be
based on generic sailplane types in actual water landings but not in
flight test situations and we really don't know what technique was
used, speed and descent rate on touchdown, pitch rate etc. This is in
the "anecdotal evidence" category.
I doubt that it has actually occurred to any glider pilots that there
might be a difference between landing wheel down on water with or
without the wheel brake applied. I stress the might. It certainly
hadn't occurred to me before the SA T6 video and then someone talking
about this being done in Alaska.
Looks like a fruitful test for the adventurous test pilots. Anyone
got any time expired glass airframes?
