Hi John - I have a LX V7 variothat has that functionality. The automatic switching of the STF is currently based on a GPS input (straight flight = STF, turn = vario). I am moderatly happy with the automating switching based on that logic. Is there a better one? I understand that the vario could also switch to SFT above a certain speed (e.g. 60kts) but I find myself flying at best L/D at times. In that case, the vario would automatically revert to "Vario". What "automatic switching logic" works best in your experience?

Thanks,

B
