Flight simulators are, by definition, all about the replication of conditions, requirements and procedures of real-world flight. Of course the focus in Light Aircraft GA & Military is more on performing Stick & Rudder VFR oriented manoeuvres & procedures while the Heavy Aircraft simulation realism is based more in the detailed replication of NAV, Autopilot & other IFR related systems.
One feature of FS2 that has always interested me is George the co-pilot. Observing his airmanship skills or quite often his complete lack & disregard is both interesting and at times amusingly curious.
FS2 has a huge advantage here. With refinement, after sending George back to flight school - and a reduction in salary - George the co-pilot could demonstrate real-world procedures as skilfully & accurately as possible, at least in some scenarios but hopefully available at all times to demonstrate gold standard airmanship. Of course, a skill adjustment slider could work well too, demonstrating exactly what not to do :? Maybe not I guess.
The point is the FS2 is more versatile than ever now, as physically & visually accurate as always but now also procedure realism adds another dimension. How can it get better?
