Hello,

Could you please check the Navigraph data for the IGS Rwy 01 approach data at LSZA ?

017° 108.9 ILU takes the aircraft slightly to the right of the runway.

If i remove the navigraph AIRAC data and use the default msfs2024 data everything is correct (_i obviously don’t want to do that_ 😀 ) but when navigraph is enabled it seems wrong.

Not sure if you need more info, but just 2 quick approaches one with the navigraph AIRAC enabled and one without should show you the difference. According the the chart this should not be an ‘offset’ approach.

Thank you !

edit : using latest cycle 2512 rev.1

Hi,  
Thank you very much for your report. I can confirm the slight offset. I will look into it more closely and analyze why this happens and how I can address the issue. Try to find a solution in one of the subsequent cycles. I will inform you here, when it´s fixed - I keep this topic open! Thank you!

Cheers,  
Richard
