Thanks Cubdriver. My current field is actually aerospace technology
working with RF communications. I have some background in programming, process automation (PLC) and circuit design to name a few.

My interest is primarily 'how' all of the systems are emulated to reproduce
certain measurements and produce an interactive display. Ultimately I'm
wondering how far back the electronics are peeled away from their jet
counterpart.

Altitude for instance could be simulated by a computer data steam that
connects directly to the altimeter hardware driver...or it may be more
complete and run through the Flight Management Computer via the
static port transducer.

In any case, I'm not looking to pull any proprietary information from the
MFG; I thought this might be general knowledge.

My last question pertains to flight data and how it can be used to
recreate a flight scenario and/or train a user. I read about the
Airbus landing in the Hudson river and how investigators used the
data from the Flight Data Recorder to playback the entire flight in the
simulator.

Apparently, the yoke and thrust are automated (along with other
controls)? Investigators could actually watch the controls move
just as the pilots would have operated the aircraft in their emergency
landing?

This is what sparked my initial post; I didn't realize the real world
jet could produce flight data that could interact synonymously with
a flight sim. It's amazing how detailed and accurate the sims. really are!
