VFR flying (navigating via intersections!)
If you plan to fly VFR ie: flie your FPL as "V" in the flight rules section, but you have the aid of an on-board GPS can you put intersections and VOR's / NDB's in your rout part of your flight plan to be filed with ATC?
I mean they may say "own nav to LIFFY" (an intersection east of Dublin, Ireland) knowing you are VFR!! is that acceptable with ATC?
