Hi Ray,

thanks for sharing your result.

I think to have solved the matter reinstalling from scratch AI Manager. The first error I did was to not installing manually (as requested) some AI models, so no models no flightplans. Now I'm using only BGL and no AIGFP. 

One compiled all flightplan I don't use Traffic Controller to inject aircraft. This is needed only for AIGFP as far as I know. But instead FSHud that's also controlling the amount of traffic. This is a partial compiled result on Fiumicino LIRF at 6:49 UTC with DELTA, ITA and other airlines, a huge difference from before:

What is not completely clear for me is:

1) the advante to use AIGFP vs BGL 

2) in C:\ProgramData\AIGTech there are a big amount of GB, I hope this is a temp data. Is it possibile to delete once done?

3) which folder we can back-up for a reinstall purpose in the future without redo all the download process (I know...outdated flighplans...)

Many thanks to all

Hi Ric,

AIGFP plans use jet routes, BGLs use Great Circle Routes.

This gives guidance.

I would backup the following including all subfolders.

C:\AIG
C:\AIG Manager
C:\AIGTC
C:\ProgramData\AIGTech
