I noticed that SD generated FPL's through Slovenian airspace will never be accepted because SD uses 'coordinates' rather than official entry/exit points. (I had one unaltered SD generated plan rejected recently for this reason). Slovenian AIP:

REF AIP SLOVENIA ENR 1.10 PARA 1.3. B. SPECIALARANGEMENTS FOR IFR AND VFR FLIGHTS (ICAO NOTIFICATION OF DIFFERENCE) FLIGHTPLANS WITH FLIGHT ROUTES CROSSING FIR LJLA BOUNDARY OR VOLUMES OF CONTROLAIRSPACE SHALL INCLUDE OFFICIALLY PUBLISHED ENTRY/EXIT REPORTING POINTS.COORDINATES OR ANY OTHER NAMES ARE NOT ALLOWED THEREFORE SUCH FPL WILL BEREJECTED.

.. not sure what we can do about that in SD. I guess we have to remember to make manual changes to the plans.

The points identified earlier in this thread were five-letter VRPs and therefore compatible with ICAO flightplans. You did not share the flightplan that was generated from your route, but be aware that ICAO designators are NOT valid in ICAO flightplans, and neither are town names, so SkyDemon would definitely have converted those into ICAO-compliant coordinates. You are of course free to reinsert town names before submitting the flightplan but bear in mind that other countries' systems may then reject the flightplan.

can you tell me which part of the FLP I can change, and whether it would be enough to put, in the REMARK section,  route in this form
