Just beginning to become familiar with programming the INS but can anyone tell me where I can get hold of VOR DME altitudes please? They are easily obtainable for flying in the US but can't seem to find any source for flying in Europe. Frequencies and coordinates are easy to find but altitudes are a problem. I may be missing the obvious but can anyone point me in the right direction?

Thanks Vololiberista for info. I am OK with the programmes and updates you have linked. My frustration is that all my flight planning is prepared before I enter flight sim. Airnav.com is an excellent site which I use regularly for flights in US. It provides all the data on nav aids you would want and if you enter a VOR identifier it brings up all the info for that VOR ie frequency, coordinates and altitude of the VOR. There does not seem to be a similar site which would do the same for flying in Europe. All I am stuck on is obtaining the altitude for VOR's in Europe. I know for instance there is high altitude and low altitude VOR's but I think that is simply a way of describing the capability which different aircraft have to lock onto the VOR signal.

Thanks Vladimir for the update. Regards
