Hello Ed,
Yes the video is gold. You should save it in case it gets deleted on day.
The Honeywell gauge looks very interesting.
So it has a double RA. One conventional and one of the TRA-45A.
The magenta arrow indicates the DH or DA I guess.
Regarding the TAWS/EGPWS I had attached a pdf, long time ago.
It describes for XPLANE a very simple way of getting elevation data. I thought you might be able to try that analog for FS9.
If this is the document which you mean, then you should look for EGPWS TAWS XPLANE C-17 Globemaster with google.
That was a real good Eureka moment regarding the visors.
Actually you could make rain effects for passenger windows this way.
(Static and during acceleration)
You should try to implement them in all your panels, like A300/A310.
Regarding the Heat effects I only know those from Nick Black AI effects.
You can adjust the intensity in his effect.
P.S.
Did you know that the conventional old style RA has a rolling tape that indicates the Height?
