Well, maybe… But that doesn’t explain why a Navigraph NavData update actually fixed these localiser alignments. But then again, maybe Navigraph deliberately shifted the navdata to match the inaccurate scenery, making it inaccurate in doing so.
Some mis information going on here. Magnetic variation or magnetic disturbances does not shift the ILS beams. This is a radio signal thing in relation to surrounding terrain, other aircraft etc. I very much doubt If any of this radio signal anomaly stuff is even modelled in the sim so I would tend to agree with @Neo4316 and say it’s a nav data issue.
That is something i dont understand eighter. But i am now certain it is not per design, i had some misconceptions about false localizers when i opened this thread.
Everything default scenery/navdata wise, FBW Airbus
