Prepar3d from Lockheed Martin has an academic license for anyone 'studying' flight simulation. It is built on the code originally from the Microsoft series of flightsims and in its current iteration is quite good. Add on some Orbx mesh and scenery (currently on sale at 50% off) and the visual realism is pretty decent.
