I Have just purchased Caernarfon Airport and installed to Prepar3d v2.5,
I am using Horizon photo scenery and have used the control panel to select this option.
everything appears ok except for a couple of issues,
1st there appears to be a ridge surrounding the airport and the airport is sunken.
2nd there is a large section of North Wales missing and Snowden is covered by water.
I have tried the scenery above & below horizons
I am attempting to upload photos.
