Dundee Airport - EGPN
Dundee is really the only prominent Scottish Airport that good quality payware hasn't been developed for.
Sim720 have been kind enough to give us Oban, Stornoway and Inverness
UK2000 have released Edinburgh, Glasgow, Cumbernauld - Prestwick is due for 2014 release
Aerosoft have done Barra
Orbx have Sumburgh and Aberdeen in the pipeline for 1st half 2014 release
I'm aware of the Scotflight scenery packages; no disrespect to the devs but it just doesn't cut it visually for me.
I think if Sim720 could give Dundee their attention then that would nicely round off all the regional and international scottish airports
