Until this summer, the IPPI Card was tolerated. Not any more. CIVL received reports of pilots being arrested by the police and charged a 300-400 euros fine for not having a proper licence. The Austrian federation is aware of the problem. At the time being, it is collecting data from several countries, to find out which licences are acceptable for the Ministry of Transport. The new rules should be published in October 2013, showing the accepted licences.
Up to now, are collected samples licences/rating cards from following countries:
BEL, CZE, DEN, FRA, GBR, GER, HUN, ITA, NED, NOR, POR, ROM, SLO, SUI, SWE, AUS, CAN, NZL, USA.
The only one that might be accepted by the Ministry of Transport seems to be: CZE, GER, ROM, SLO, SUI.
