Which file actually holds localiser freq information?

Recommended Posts

I've taken on the responsibility for making new sid/star information available for VATSIM's users for India, and I've noticed that some of the airports don't show ILS information in the FMC when you're coming in for approach.I started to look for where this information is found to see if it's in the SID/STAR files (it doesn't appear to be here), and I also checked the navdata site, and the files that you download with the AIRAC don't seem to contain it either (I'm not -positive- about that, but I looked in each of the files you get and can't see anything that looks like the ils frequencies in there).Where is this information stored, actually, how do I go about adding it for runways that aren't currently there, and who do I send this information to?Thanks in advance,Jeff Clark

The primary data source is wpNavAid.txt file (AIRAC data) located under the FMCWP directory. It is also encoded in the runway data for the airport in the wpNavApt.txt file (freq only). You can verify that the localizer is in wpNavAid.txt by opening it and searching for the ident text string (IABC for example). If it's not there, it's not too hard to figure out the data structure and you can add it, but you'll have to provide what has to be added to where for other users of your procedures. For an example of how I've done it you can look at my KMCO procedures from www.navdata.atYou can try sending the info the navdata, but if the FS9 doesn't include the navaid then either a bgl or AFCAD file needs to add the facility. This is what I had to do for the new runway at KSTL.
