As you may be aware, the Working Title Team has been one of the most popular Modifications to improve Autopilot and Avionics systems on the Garmin equipped planes in MSFS.
They have now joined the MS-Asobo team in a formal partnership, which means those previous volunteer efforts will now become a full-time dedicated improvement to the core simulator. In the meantime, they will continue to provide their Open Source and frequently updated changes to the general public.
Please see the announcement thread for more details. And if you’ve not tried the Working Title Mods before, I encourage you to do so - it so greatly improves the immersion and experience of the sim.
