I kind of explained that in the post before. You approach the runway and then you look in the front and concentrate always on the height between your Autopilot panel and the runway. If you keep the same distance until landing, you will be landing directly on the threshold. With that i don't mean the actual distance, only the distance you see with your eyes out of the cockpit. Or if your runway has PAPI's you can just follow them. So 2 white lamps and 2 reds is the right altitude, 3 whites and 1 red is to high, 1 white and 3 reds is too low. And don't overcorrect on approach. Just minor corrections by pulling/pushing slightly at your joystick. Pitch is difficult to use if don't know what value you need. Another thing is the speed. You can loose altitude fast if you are too slow. Hope that helps, SwissCyul
