ILS freq in FMC

Recommended Posts

Does anyone know where the PMDG 737NG FMC gets ILS frequencies from? In other words when you select an ILS approach in the FMC how does it know the frequency? I flew into KSTL today and selected the 30L ILS approach and in the App REF page it had the wrong freq.

Some airac cycles listed the LDA freq before the LOC freq, and the FMC only picks up the first available freq for any runway. Stefan said he was going to fix that during Cycle 0611...but I just check cycle 0612 and the LDA is still listed first. Look in file wpNavAPT.txt, search on STL... you'll find the LDA (111.75):LAMBERT-ST LOUIS INTERNAKSTL30L11019301 38.738078 -90.347061111.7530200586listed before the ILS (111.50):LAMBERT-ST LOUIS INTERNAKSTL30L11019301 38.738078 -90.347061111.5030200586Either swap those lines or delete the LDA if you don't fly it.The data format includes airport name, icao, runway id, length (11019), course (302), latlon, freq (111.50), and elev (586). The column is significant, gotta use real spaces instead of tabs.Hope this helps. Maybe more than a couple of us need to complain, especially since we are now paying for the data.

Thanks so much Dan I didn't realize it was coded that way in the file. I'm going to go test it right now.

Thank you for spotting the thread. I had no doubt that you'd take care of the LOC/LDA issue as soon as you learned of it.
