I’ve spent enough hours in flight simulators to land one. The trick is to level off at zero throttle and reach stall speed just above the ground, and let the plane drop onto the runway on its own. That way, you are certain that the plane touches the ground at the lowest possible speed.
I’ve been doing MSflight sim since it’s very first edition 40 or so years ago. At this stage all I sim fly are jumbos. I know most of the speeds and flap settings etc for landing Boeing, Airbus etc. And all the procedures to land like butter on bread.
I play with all realism on with absolutely no aides enabled. So yeah, I could land it even without ATC as long as I have the right chart and clearance. After all, I land them all the time in my sim.
If you pull the throttle at an airport at a high elevation, you're coming in hard.
