Never mind I just figured it out.
tell us how please.
For anyone still wondering, to update AIRAC cycles for the 747-8I V2.1.1 (Steam version of X-Plane 11)
1. Create a new folder titled "UFMC" in your Custom Data folder. The resulting path should be: C:\Program Files (x86)\Steam\steamapps\common\X-Plane 11\Custom Data\UFMC
2. Open your Navigraph FMS Data Manager and add the "SSG Boeing 748i, E-Jets Evolution" addon.
3. Set the installation path to the "UFMC" folder you created.
4. Update and reopen X-Plane 11. Load the SSG 747-8I and verify AIRAC cycle is updated.
