@anon50268670 hmmm. Letās see, he is CAT2. CAT1 is gone missed in (at) November, and CAT3 has taken off this morning without filing a flightplan. So thatās the cat status atm.
The ILS for KPIT Runway 28L is off.
Instead of heading 281, it went for ~265.
I didnt correct it manually and just let it do its thing till I crashed into the woods next to the runway.
I didnāt understand you correctly, you said " I didnt correct it manually" which gave me the impression that you had a choice. Which in real life, of course, you would, sorry.
Like @PZL104 says, you canāt change the LOC course the same way you select a VOR radial. Even in real life where you might need to set the final approach course manually, the CRS you set practically doesnāt do anything, its just an annoyance having to fly an ILS with the CDI 30 degrees off for example, having to rotate the picture upright in your head.
The only purpose of setting the ILS course is to have a correct picture displayed on the OBI, HSI, ND or whatever instrument you are using. In other words, if the CDI shows one dot deviation to the left, you can turn the course selector 360 degrees around, it will keep displaying one dot deviation to the left the whole time. You can try it on the steamgauge C172, the course you set is completely irrelevant.
There is however a really stupid bug in MSFS, for some reason you can make the RMI or bearing pointers (blue needles on the Garmin) point towards the localizer antenna like it is a VOR or NDB. This is completely impossible in real life. You canāt home towards a localizer antenna like its a conventional beacon. The principle of operation is entirely different.
Iāve been using NDBs VORs and ILSs for years but Iām sorry that I donāt understand the concept here. You tune in the frequency and dial in the bearing or radial. As far as Iām aware you can use a localiser in the same way as a VOR.
The big difference is that with a VOR you can select any radial and fly on that radial towards or away from the beacon. You canāt do that with an ILS, you can only approach the localizer from the front (front course) and maybe from the back (back-course) but you canāt select, lets say 90 degrees off from the localizer course and approach the runway at a 90 degree angle. You can only receive the localizer directly from the front or directly from the back plus minus a few degrees and the course you select is only to make it easy for yourself, you could set CDI 30 degrees off and still fly the ILS, you are just making it difficult for yourself by not having the CDI point in the direction of the runway, the fly left / right indication remains unaffected.
Using an OBI like on the steamgauge 172 the OBS is not doing anything at all as soon as you select an ILS frequency. Try it in MSFS, line up on the localizer and turn the OBS, its not doing anything at all.
