MSFS 2024 - iFly Max constant error on ILS approach (app/rw error)

Hello

I wasted now 8 hours and still am unable to use ILS with the iFly Max… I know how to do an ILS - did many with PMDG 737 and many many other airplanes.

What I checked:

  1. Navigraph is up to date incl. iFly 737 - checked in Navigraph Hub
  2. ILS Frequency is propperly dialed in (to be sure in both radios)
  3. Approach Ref is selected (30 Flaps)
  4. NAV is set to rw course
  5. HDG is set to rw course (optional - but I was getting desparate lol)
  6. Speed and Altitute are all perfect

But as soon as arrive at the GS and hit APP I got the app/rw error in FMC.

What is going on here? Any idea? It’s really getting ridiculous - I do ILS for over 20 years and now I can’t anymore? Is this a bug?

Thanks for your ideas all :slight_smile:

OK - and here is the solution:
In the approach page where you select your flap settings, you can also see the EXACT approach course. Make sure to enter this course also exactly the same on the MCP and you’re golden.
