Lancair crash at SnF

Hi,

OK, too much noise here, let's just refrain from replying to personal
attacks shall we.

Anyway, speed is the magnitude of the velocity vector. In a constant speed
turn, speed is (obviously) constant, but the velocity is continuously
changing. This is by definition. It doesn't matter how you or anyone else
uses these terms. Speed is just a number, Velocity is speed plus a
'direction' variable. Since acceleration is the rate of change of velocity
(dv/dt), the above mentioned aircraft in the constant speed turn is
accelerating.

yeah but you got creamed in this thread! :-? :/ :') Þ lol
WingFlaps expressed precisely :
Stefan was doing quite well actually,

But it's relative to space, not the earth, as I posted earlier.
Earth pulls straight down, nothing more. Do this, as we have done many
times: Go out and fly on a day when the upper winds are at 30 or 40
knots and get under the hood, do 30 degree banked turns, maintaining a
constant altitude and power setting, and see if the airspeed changes.
Got to be done over flat land, BTW. Any orographic lift will screw up
the altitude. You won't see any performance changes, but the
airplane's flight path over the ground sure isn't circular. Try 45
degree banked turns. Try it in a glide. See if you can prove me wrong.

WTF? I wasn't talking about speed over the ground...
