RE: IFR into Weston
I had absolutely no problem. If requested to make an RNAV approach just inform ATC that you are not RNAV equipped. Has never happened to me on the approach as you are always just radar vectored.
The more likely problem is on departure when tower may tell you to make an RNAV SID. Again, just tell them you are not RNAV equipped and they will give you alternate instructions.
Note that when filing your flight plan the great Eurocontrol computer will automatically fill in the RNAV SID/STAR for you, so the copy ATC get will indicate you want the RNAV SID. It may help to put a note on the flight plan that you are not RNAV equipped although they should be able to work this out from the absence of the 'R' in the aircraft equipment.
