The HSI is showing the Chinook centred on the localiser off to one side (photo as an example). I have tested this at several airports and verified in another chopper that this is a Chinook problem, not a general ILS problem. I haven't checked if this affects tacan or VOR navigation as it's a lot harder to see if a radial is correctly aligned.
Miltech Simulations @MiltechSimulationsWe are aware of the issue and its currently under investigation.

Great, thanks. I did wonder if you were using true bearings instead of magnetic or vice versa, but my photo was taken at Rio with a large magnetic variation and the effect seems the same size as in the UK with small variations.
Miltech Simulations @MiltechSimulationsThat could very well be the case. We are using the stock ASOBO templates for these instruments, so it will need a little bit of digging.
