I am unsure which section to post this in - but we start here.
We already have the instant replay feature, which can re-create some part, or all of a flight, without the external scenery.
From this, one could derive an aircraft reduced to a very simplified graphic symbol, on chase view - or similar.
In the same way, simple symbols showing things like a side view of an aileron outline moving up or down.
Then, just like the live telemetry used in Formula 1 racing, there is the possibility to have graphical plot records of (say) instrument readings, aileron and rudder positions, etc.
To take this concept all the way, suppose we have the datalogger capture of these things, taken from a real flight. This data would be similar to what might be available from a aircraft black box (OK - it is orange, but we move on).
This is not supposed to be about crash analysis, but a training aid, a kind of post-flight forensics!
The real aircraft is instrumented to record the important control surface movements during a flight, plus some instrument readings, and possibly G-force. The real flight is also captured on pilot-view video from a dash-cam, or similar.
We now have all the ingredients to see the plots showing the things that happened during the flight, which can be played back together with the video of the real thing. There is the possibility that others have already done something like this with flightgear, but I had to ask, because my search did not find much.
Is this notion realistic?
