Hi Tim, I know I am riding your nerves, but here it goes again:
I have now checked various Airports in Europe with the Standard Garmin/Jeppesen Aviation Database, which gets loaded every 28 days into on-board devices.
This database (at leaast for Europe ) contains now VRPs and even displays them if the latest SW is installed on your onboard devices. SD also Shows These VRPs on the map!
The naming convetion they use is ICAO identifier minus Country Identifier i.e: for UK White Waltham EGLM = LM only, or Vöslau Airport LOAV = AV and then 1-3 letters of the VRP idenitifier. This is now true for most European countries.
When I plan a route with SD over these VRPs and Export into G1000 or GTN Format, they get strong names/numbers which do not resemble the VRP identifier. I have checked again and again and even found in the latest (December 8th) database a lot of VRPs even in UK (you might check out
http://www.thehangar.co.uk/waypoints/waypoints.shtml 

So the nomenclature is equal over Europe (EGLM has LMS, LMW, LMN for example) why does SD still not use the VRP names which all Cockpits in Europe use, when they use the Jeppesen electronic Navigation database?
As per DCT and/or coordinates please note that Coordinates in FPLs in Austria will not be accepted, same as in Slovenia and Germany! If you use a City for example as a waypoint you MUST specify the City Name in the VFR Plan....
I hope SD will consider this in a future release. If you want, I can copy a European Nav DB Example from Jeppesen to you, which conatains ALL Vrps in Europe (including UK) :-)
best regards
Erik
