I added an ILS to my airport in the scenery editor by clicking on the runway and adding the ILS on the drop down (secondary runway ILS). I added the frequency (I put in 108.7 MHz but it kept changing to 108.699999 MHz… not sure how to fix that), correct heading and glide slope etc, but when I loaded up in the sim and put in the frequency, it didn’t register or show up on the needle / nav display.
Try changing it to the primary runway… It worked for me, as it seems to be reversed compared to the other settings. You could also test this by approaching the other end of the run way with the frequency and see if it captures the ILS there.
Thanks. I ultimately realized that I was overriding the ILS system with the “deleteAllILS” box checked, so getting rid of that fixed the problem. Odd that it bugs out though.
