Several times I had the experience, that temporary RAs (e.g. for military exercises) that were announced by (national) NOTAMs giving a huge circle around a specific location were also shown in neighbour countries, where they are clearly not valid. For example a Czech TRA for sure has no relevance in German or Polish airspace, as the authorities of one country do not have legal competence in another country. Such false map-markings in the not affected country are misleading and confusing. If there really are multi-national TRAs (which may rarely be the case), then the respective national parts of it would be published in each nation‘s own NOTAMs, adding up like a puzzle.
Therefore I highly recommend to create an algorithm, that the highlighted TRA on the map ALWAYS ends at the borders of the respective country which issued this specific TRA - even if the original NOTAM specifies a huge circle that reaches beyond this countries borders.
People said: the marking on the map is as unprecise, as the NOTAM itself may be. That‘s not a valid argument: The NOTAM legally assumes, that its validity ends at the borders, therefore they should be read and interpreted accordingly. So should SkyDemon do.

Very qualified answer for an aviation IT expert, Mr. Erchegyi. Is that the current usability and safety approach in Lufthansa culture? Is this your usual approach to discussions about possible deficits in human-machine interaction?
