We are looking to fly from Drezden to Karlovy Vary. We have filed DCT flight planes (VFR & IFR) but all were rejected due to border crossing points. We were told that we have to fly further south inside germany then cross and fly north to K.V.
Have you got an IR? If not you cannot file IFR outside the UK.
If you want to fly around Europe IFR you need to use proper tools e.g.
FPP. See some of my IFR trip writeups (on my website) for the planning process.
There are no border crossings to be specified on IFR flight plans. Only on VFR ones do you put the ETA to the FIR boundary.
If anybody can find a reference to EASA rules or proposals on cost sharing, I would be very interested... I am doing a "VFR to Europe" presentation and there are a few bits I am having problems locating.
