Hello! I like to do long haul flights in the Samen XPP A330 (a very good freeware aircraft), and it has a very good and straightforward 2D cockpit. I am able to load my flight plan into the default FMC, and I can set all of my autopilot fine including my HDG. But the localizer doesn’t work, which is a necessity for long flights! I have done everything right! Any help would be greatly appreciated!!!
