We’re aware of user reports of sim crashes on PC experienced by Navigraph users following the installation of Aircraft & Avionics Update 3.
While all teams involved investigate, a user-submitted workaround is available by disabling the AIRAC Cycle 2409 rev.1 package within the Navigraph Hub app.
UPDATE 2024-10 @ 0350 UTC: As an alternative to disabling the AIRAC Cycle 2409 package in Navigraph, a different workaround is to uninstall the “Bush Trip - Scotland” package from World Update 17: United Kingdom and Ireland. This will allow you to continue using Navigraph along with AAU3. Thanks to forum user @RookieOneqc who discovered this workaround.
