I like the way you sum things up. That's exactly what I wanted to say in
a much less understandable manner. ;-)

That's more or less the way it is.

Now that would be nice... Actually, our symbology is probably
non-standard. However, I've tried to search the internet for
"MIL-STD-1787A" (or B or C or D), which is a document mentioned
(incorrectly as MIL-STD-1797A) in FlightGear's README.xmlhud and the
document itself does not seem to have been published on the internet.
Maybe you have to buy it ? Or can we request it from an official source ?

Of course...

Maybe that's the easier way to put it, although it is not that simple.
Part of the answer is in Rick's post.
