Hello, I'm planning to fly to the Aero-Expo Friedrichshafen show
www.aero-friedrichshafen.de with two private pilot friends in a PA28 from Biggin Hill (Cabair). We're IMC rated with good experience of flying in north west France and generally making trips away. Flying further east into France and Germany will be new to us though and so we'd welcome advice with regard to good navigation routes, avoiding restricted areas, busy airspace and so on. My first thought is to fly south of Lille, past Metz then south of Strasbourg. I can see a lot of class D airspace to negotiate as well as high ground. Any other suggestions for routing? Thank you. Regards, Neil Geddes
