A good and useful article, I hadn't seen that one. Thanks for posting it.
Perhaps I should clarify my point.
My observation has been simply that the Microsoft flight sims are a self contained world, and answer to no reality other than their own code, their own graphic event presentaion.
One can have (perhaps) a NACA profile for a given wing type, repleat with test graphs and all long math , but the scientific data simply will not translate into FS' scalars, switches and tables.
The simple writing of a pilot's report, or the verbal reflections of a pilot experienced with the aircraft in question may be far more valuable than the long math equation of simple dynamic coupling. An illustration of a flight test telemetry report may look impressive, but any of us will quickly bypass that and dig into the written report to try and figure out just what the aircraft did, and why. (and how, and exactly at what stage of the flight envelope...?!)
I'm aware of more than one flightsim enthusiast who hold pilot's certificates, some of them very highly accredited, who enjoy the physical side of flight modeling.
The main challenge has not been to understand how the real plane behaves. They already have the bruises and band aids to show that.
The challenge lies in squeezing a convincing replication out of Microsoft's coded simulator. How to (get) the simulator to speak Super Cub/Spitfire/X-15......(?)
That's where the abstractions kick in.
Please don't misunderstand, I'm not criticizing Microsoft's program. The physics engine buried in Flightsim is an astounding body of code.....simply beyond brilliant,
......and.....it's a universe within itself, given to it's own values, the numbers generated within designed to drive a beautiful piece of showbiz. A little engineering helps, but surprisingly.....more interpretive detective work and translative ability may be required.
However....the neat thing about the process and the format featured here, is that anyone can figure out their own way to kick the can down the road. It just takes interest and enthusiasm.
There seems to be tons of that here, and the X-3 is certainly a good and exciting subject within which to explore the far out abstraction of Flight Sim, and see how convincingly it can be brought home to the end user.
My blessing, X-3 should prove to be a fun and expansive exercise for you!
