@ TurtleX696 My experience has generally been ok with the default a320 when using the Avialsoft EFB, in effect you create/amend the flightplan and the EFB injects it to the plane rather than using the FMC. I have no deep understanding but it appears when I load a flightplan from Avialsoft EFB it sends it ‘deeper’ somewhere. The flightplan generated from the MSFS main page shows on the PFD, but the Avialsoft EFB flightplan (which might be different to the MSFS generated one) sits elsewhere. The plane flies the Avialsoft EFB flightplan, not the MSFS one. Generally the a320 follows the EFB one but does throw a wobbler everyso often, but clicking the ‘Direct To’ in the external EFB to the next waypoint gets the show back on the road. If you adjust anything directly on the FMC, then the MSFS flightplan kicks in and all goes to pot. After the update, could no longer track the ILS irrespective of what flightplan in operation, hence now using the FBW (with fix) until the default gets patched. In reality, have no idea what 's going on - just hope it gets fixed soon!
