In the form of the Swiss Soaring Society there is a link to a link to a regulation of the Italian aviation authority about Transponder requirements in Italy.
http://www.fivv.it/documenti/2003/Reg-Transponder.pdf
In Paragraph 1.2.f it is written 'a partire dal 30 giugno 2004 tutti i velivoli e gli elicotteri che operano nello spazio areeo italiano in aualungue classe di spaci aereo'
I don't speak Italian, but as far as I can understand this means transponders will be mandatory for gliders from 30 June 2004 Is this true?
