I'm well aware that GS is not representative of aircraft performance, but it's also a guilty pleasure to track 'em :) One figure I'm truly interested in is what the maximum sustained true airspeed is in level flight for various Lancair 360s. I know my plane is good for 197ktas with me in it...no more and no less. I actually use that information as a gauge for how the plane is doing on any given day. One day I was getting 202, sustained for a few minutes in level flight. That got my attention. It turned out to be a very slight updraft. I paid the piper later on, though, entering a similar downdraft, taking me down to around 185ktas. Groundspeeds are fun to giggle over. True airspeed in level flight is something to admire. I'm guessing the cleanest 360's with 180hp power plants are good for around 205ktas, perhaps?
