This plugin saves the Auto Brake, Auto Thrust, HF antenna and VOR/INS/FMC options on leaving the aircraft or changing the aircraft's livery. The fuel weight is also saved.
The settings are saved on a per-livery basis in X-Plane's Output/B720 folder.
The folder structure is as follows:
Output/B720/<Model>/<Livery>/persistent-loadout.json
These settings are restored when you load into the aircraft or after changing it's livery.
To install, download the latest release, extract and
copy the persistent-loadout folder to the aircraft's plugins directory.
If you want to reset the options for a particular livery, just remove the corresponding folder
from inside the Output/B720/<Model>/ folder.
