Open Climb
Not sure if you are a pilot but if you are you will appreciate that all simulators are poor at reproducing the landing phase because they lack the richness of visual cues.
I have used MSFS in the past to practise map reading (how good are you, nowadays?) and on occasions to take-off my 747 from local grass fields.
If you say "I hope you are joking..." it doesn't really add much to the discussion because you don't reveal what your point is. I have met a few people who have landed full-motion simulators even though they are not pilots. By contrast I've see several people with no hope. So I think the person who started this thread is probably correct. An ordinary person has a very low probability of saving a plane whereas a PPL has a high probabilty providing the meteorological conditions etc are not too bad.
By the way it's nothing to do with FMSs. ATC will do all the navigation for you. It is can you land a big jet?
