ETE calculation in LX90xx
I have been using the 9000 series for several years. The ETE based on Average Speed + Vario works surprisingly well unless you get low and have to dig out.
To quote from the manual:
"All four methods of calculating ETA and ETE (Estimate Time of Arrival & Estimate Time Elapsed) take into account glider altitude, wind and safety (arrival) altitude thus ensuring that the calculation made is the best possible."
