In 'Pilot' magazine about 4 years or so ago, this very situation was discussed by Editor Nick Bloom and retired BA Captain Bob Grimstead. Their telephone discussion led to an article by Bob Grimstead into the hows and whys of this very scenario, and led to the conclusion that the guy most likely to get anywhere near success was the guy who flew airliners on autopilot on MFS because the systems are pretty well in tune with the actual aircraft they purport to represent. As for the manual landing, his verdict was a most definite 'NO'.
Is there anyone out there who can post the article.? It made interesting [and sobering] reading.
