Well, in Austria you could visit the home of Diamondair at LOAN (Wr. Neustadt), IFR procedures here

This sits close to the Hunagrian border south-east of Vienna. If you arrive IFR, you won't have a problem, VFR however beware: Wiener Neustadt has TWO airfields! One LOAX is mil, the other, LOAN, civ. And coming from the west you route around/along LOAX to get to LOAN
