I just noted a small "bug" probably present in all versions of SD. When planning a border crossing flight and adding a published border crossing reporting point, SD will still add its own border crossing point in the flightplan in lat/lon notation. To wit, a flight from Graz (LOWG) to Maribor (LJMB) with a border crossing point of OLMOT will still insert another border crossing point.

I suggest to omit the calculated crossing point in case there already is a waypoint in the flightplan which is within 5 miles (measured along the planned route) of the physical border crossing.

Also, what were thise superfluous DCT's in the route portion? In Austria this drives the controller crazy. Have got an admonishing call twice because of them.

I'm afraid Austrocontrol are rather unusual. They seem to have a very specific view of VFR flightplans and what should (and should not) be included on them, which contradicts the view of every other European state with whom we deal when it comes to flightplans.
We looked in to doing EET/POINTxxxx in the past and discovered that while some people informally do it, the correct ICAO way to do it is to name the FIR, which we already do. I believe (despite what Austrocontrol might say) that we are doing it in the correct way. Certainly there haven't been any problems with the receipt of flightplans (Austrocontrol excluded) that include this method of specifying arrival point at the FIR boundary in the years we've been sending them (tens of thousands of flightplans).
We could omit the DCT, but why would we? You're supposed to have them to comply with the ICAO flightplan specification, and only Austrocontrol objects to them.

Well, just to prove I'm not making this up it is all spelled out in this document:
http://www.austrocontrol.at/jart/prj3/austro_control/data/dokumente/bbABB_227_tcm586-72348.pdf

Specifically, according to ICAO, you are supposed to use DCT if the departure point is not on an ATS route, followed by the first point on the ATS route and then the route designator. Or, if you are leaving an ATS route, use DCT before the first off-route point, except if both of these points are specified by geographical coordinates. For flights off ATS routes, use DCT between successive points unless both of them are given by geographical coordinates or radial and distance from a radio navigation aid.

So, it seems you are doing it correctly if, indeed, you abstain from using DCT between points given in lat/lon format (I haven't checked this yet.

Austrocontrol do, however, specify that for flights inside the FIR Vienna, DCT must only be used by flights of the Austrian military if their mission so demands and flights for geographic surveying.

Oh well, -- Chris.
