Please define for me what is specifically modeled "very simply" in Aces High
or MSFS.

The dynamics of the airframe. Frequency, damping, poles, zeros,
transfer functions, the stability and control coefficients of the six
equations of motion, the atmosphere, the actuators, controller
dynamics, mass characteristics, that kind of stuff. As well as the
flight control system.

The mathematical model of the vehicle, in other words. That which
makes each airplane fly like that kind of airplane.

I spent a lot of my career determining this stuff so it could be put
into engineering simulations. Read Iliff & Shafer on the estimation
of S&C derivatives for the Space Shuttle to see how we determine such
numbers and put them into the mathematical model used in the
simulation. You'll find it on www.dfrc.nasa.gov, in the technical
reports section.
