The ILS in the scenery are surely correct, meaning:
They are inserted using True heading, as they should, with the correct indication of the Magvar. For example, RWY 8L is about 100° Deg True with -18° of Magvar for the area results in a reading of 82° on the instruments.
If the readout on the instrument needles is correct ( and it surely is ), the problem here is ONLY the wrong course automatically set by the instrument, which seems to indicate a bug in the sim ( or the instrument code ) of not taking into account the Magvar which IS correctly set in the scenery ( otherwise the needle would be wrong too ) when automatically set the CRS.
It's *possible* there's a bug in the sim not taking into account the Magvar, but I think we should stick to set the ILS correctly, meaning the heading is set to True, and the Magvar is set because, if we tried to be smart and "fix" the error, by setting the ILS to its Magnetic course and the Magvar to 0, the following will happen:
- Asobo might fix the bug in the meantime, resulting to a wrong readout.
- The Magvar might change with an update, and the readout would be again wrong.
So, I think having to check the CRS to be correct and not relying on the automatic selection is probably the best choice right now, better than purposely set the ILS wrong in the scenery to make the instrumentation happy.
