At Armidale, NSW (YARM), the tarmac and taxiways, even though the correct dark colour, are covered in grass, with no taxiway lighting. This is not the case in real life, they are asphalt, with lights.
Apron at Armidale (YARM), NSW, Australia made of grass instead of asphalt and missing taxiway lights
That bugged me also, I did some modifications for it (taxiways, aprons etc) which I’d be happy to share with you, but it won’t let me include the zip file or a link to it.
Sorry for the long time lag. This has been addressed in the Australian update. Not as good as add on scenery but better than the original. Armidale apt still looks a bit fake and FSXish.
