A321 XLR - Systems/Sound Mod

I should add that I don't own or Mac and won't be purchasing one, so I can't test any of this. This is just a hobby for me, I initially created these mods for myself as a stop gap until the devs do their own versions, but that could obviously be years (if at all)

Whilst all the fault overlays will work on Mac, the actual code driving the random faults is through PowerShell and Python, and I have zero clue how that works on Mac.

What the Mac version will need is a GUI, and more more importantly, a script that copies each failure into the respective system and parameters files. Below is an example of the code for severe faults like engine failures.

Also, these are the paths for Aerofly in FS4 and the PC version; the equivalent paths need to be located for Mac.

FS4 PC mods go here \Documents\Aerofly FS 4\aircraft\a350_1000

FS4 Steam folder - C:\Steam\steamapps\common\Aerofly FS 4 Flight Simulator\aircraft\a350_1000

FS4 Failure mod lives here - \Aerofly FS 4\aircraft\a350_1000\A350 DISPATCH (folder name needs to be changed to lower case for other platforms, works fine on PC)

I'll try to assist as much as I can, but the whole mod took me a long time to create on PC, and my time is limited. Thankfully, all the system failures are cross-platform, and that was the hardest part.

THIS IS ONLY PART OF THE SELECTOR CODE - Each component is weighted with a random chance of being selected and injected into the sim. For example, an engine failure is set to 1 (extremely rare). The hydraulic yellow system is set to 10 (still rare). Medium and minor faults (Electrical, Pneumatic, flaps etc) are dealt with separately and are more common.

The 'Weight' determines the likelihood of a failure.
