Brief description of the issue:
So this bug is still happening to me. I was hoping this was fixed with the recent update, but I guess not? I just updated the game and took 747-8 out for a spin. I did an ILS high altitude flight, so was expecting a steady ascent to FL42 after takeoff. But lo and behold, after I cross FL10, ATC tells me I’m 500 ft above assigned altitude and I need to descend. I check my Barometer reading and everything seems to be correct (29.92 IN). This was brought up recently in the other closed thread, but I’m not sure why this is still happening. Anyone else?
