The 'classic' FLARM, without the IGC approval and seal, qualifies as
"Position Recorders" in Germany and France; without an additional
barograph.
Ironically the simplest and most prevalent type of "Position
Recorder"...
If you want to have it approved in your country, just let your
National Gliding Authority know:
