Physics, software and aircraft engineering expertise are only going to help you so much. It's enough to build a general purpose sim, but to simulate real aircraft you also need real data, which is often a trade or a military secret, as DCS developers learned the hard way when one of them got arrested for alleged smuggling of F-16 manuals. For a serious sim, you need a lot of communication with the aircraft developer, and a lot of money for licensing fees.
