What it changes

Adds a voiced ATC client with keyboard and menu controls.

Red Griffin ATC is a community add-on for FlightGear. A full speaking controller for VFR and IFR procedures using FlightGear's speech synth. PlayBound unzips the add-on into FlightGear's Addons folder, then Play FlightGear — PlayBound passes --addon for each installed module. Mods are versioned separately from the base game — match the recommended engine or client release before joining multiplayer, and keep a clean backup of your settings if you experiment with several packs at once. PlayBound only lists projects that publish redistributable archives or clear external download pages. Always read the upstream README for credits, required assets, and known incompatibilities.

Compatibility: FlightGear 2024.1+ addon module (`--addon`)

Install with the PlayBound Launcher

The launcher installs this into (game root) for FlightGear. If the base game is missing, it will install that first.
