So at the moment when I setup an ILS landing at any US airport I use the information on Airnav which tells me what stage of the approach to intercept the glide slope, the nav frequency etc.
I was under the impression all the airports navigation data is contained within the worldmap. I believe, if this is true, you have to really drill down into the location, and eventually it is there. You also have to setup an arrival AP and then just zoom into the WM until it provides the map, as I have seen examples of it doing that. I have not tried it, as my sim won’t work now.
This is map linking to official AIP databases for different countries. Some of these are in the public domain, some may require registration, and some are restricted (you may have to pay to get access).
I assume this functionality will be coming with the NavBlue Charts+ option for MSFS, but no word yet on when that will make its debut. I strongly suspect that Charts+ will come with some kind of DLC fee, unlike the NavBlue AIRAC data that is embedded in the sim.
Navigraph Charts is another current option, though it is also a paid subscription service.
As others have noted, many national AIP agencies in Europe and elsewhere permit downloading current approach charts for free, but for a flight simmer, that would involve keeping track of multiple different web sites and log-in credentials.
One advantage of a service like Navigraph or Charts+ is you would get immediate access to procedures for many dozens of countries in one unified application.
navigraph airac doesn’t work with fs2020. Besides that AP/FMC/MCDU is completely broken in the current version…so there is no point in paying for the navigraph subscription yet.
I wasn’t referring to the core nav data in the sim itself. The OP’s question was about sources of approach charts for airports outside of the US. Navigraph is one option to obtain worldwide charts, but there are several free sources as well.
Some good websites are: www.airnav.com - mostly US locations and some outlying locations. www.skyvector.com - I think worldwide locations via sectional charts, good videos on YT to read them. https://www.mypilotstore.com/mypilotstore/ - pay for stuff here.
However, in the Sim, under the world map, I think all the information is contained for ILS, etc., via which runway you choose to land on. I think you have to select high altitude airways, but could be wrong. I know I saw that information there just a while ago, while planning flight from KATL to KCHA. I did not setup an ILS approach as i was flying C172G1000 - don’t like G1000 way too much stuff to learn, but this link shows how to use and operate it very well. https://www.youtube-nocookie.com/embed/5e8FiFzoZsU
