In addition gliders come under the aegis of EASA (in the EU) which

fitted when the glider was transitioned in was accepted.

As I understand it, only the required instruments need to be
certified: ASI, altimeter and, in motor gliders only, compass.
Otherwise you can fly with what you like, just as power pilots have
been flying for years with non-certified GPS receivers, and nobody
needs a certified wris****ch.
