Aerofly is by far the best flight simulator, but not finished yet. I tried to fly from LSZB to LSZA with a flight plan. The flight path is well chosen, but the altitude is deadly, because it collides with the terrain several times and leads through uncontrolled airspace. If the automatic flight planner does not set a sufficient altitude itself, you should at least be able to manually enter a suitable altitude for each waypoint. Or do I see something wrong here?
