Any feedback, suggestion, criticism and hint on how to improve this addon are warmly welcome. Red Griffin ATC is written in Nasal language and it has been tested in Flightgear 2019.1.1, 2019.1.2, 2020.2.0, 2020.3.x and 2020.4.0 git, specifically in my Fedora Linux FC33. I hope everyone will enjoy this addon as much as I did in developing and using it. I started this project a couple of months ago as I have always wished to have a similar addon or service in Flightgear.

I am also posting a couple of demo videos in which you can see my Red Griffin ATC addon in action and what it can do. I want, in fact, to give my personal contribution to the Flightgear community with gratitude for the countless hours I have spent in using this amazing flight simulator in the hope everyone can enjoy my addon and find it useful.

Red Griffin ATC is an Open Source project and will be released under GNU Public License Version 3 (GPLv3) and can be download from its repository at. I am very glad to announce my Flightgear addon for a speaking Air Traffic Controller.
