Which glide ratio needs to be achieved for glider to be considered as a sailplane?
Actually i would like to know if the Pipistrel Taurus still can be considered as a sailplane if its best glide ratio is actually below 30 despite in theory it was supposed to be 1:41
Thank you very much gentlemen.

There is no such official distinction. A widely accepted definition is that a sailplane is a glider designed to fly efficiently and GAIN ALTITUDE from natural forces, such as thermals and ridge lift. Therefore, given sufficient lift, even a low-performance glider can meet the definition of a sailplane. German gliders of the 1920's certainly can be called sailplanes and they had glide ratios in the range of 18:1 to 22:1, allowing them to soar for extended periods in 20 mph wind blowing accross the Rhone mountains.

It isn't glide ratio or even sink rate. If it can gain altitude from launch altitude it can be considered a "sailplane". If all it can do is descend it's a glider.
Just like Z B already told you
