Hello from the USA !
So I decided to give this a try - moreover that's such a noble cause - but upon following the instructions "EGLW" is nowhere to be found when selecting an airport (P3D 4 3). Then it seems obvious as the "addon file" is missing in the download. Which is confirmed when launching P3D 4 3 as I am not prompted to accept the addon in question.
I will add them all on here for download
