I'm using the last version of FlightGear (2016.3.1), and I don't know how does the autopilot work now. I tested more then 20 different models of aircrafts, more than 30 different airports, and I set a flight plan, but even though I activated the autopilot, it didn't follow the instructions I've set on the flight plan. And it seems that nothing is working (the LNAV button, HOLD altitude, HOLD speed), inclusive when I try to do an ILS landing, the LOC and APP button didn't work, too. I don't know what to do ....
Hope someone can help me.
