MSP Class B

Well, I stuck with it and got some tips from a Google Earth user in Australia.

Anyhow, after a whole bunch of messing around I was able to display a good chunk of the MSP Class Bravo airspace in 3D via Google Earth.

It turned out to be a bunch of work, but once I figured out how build a three-dimensional circle and shade it the work was just tedious cut and paste/search and replace.

The end-result is actually sorta neat. I haven't figured out how to display the odd shaped bits of the Class Bravo that extend beyond the 20NM ring, but if I can figure out how to get the lat/long coordinates that define it I'm guessing it'll be simple enough.

Here's the .KML file if you want to download it and check it out for yourself.

Also, I couldn't find a lat/long for the I-MSP 30L localizer/DME that is used to define the distances for the airspace lateral boundaries so I used the MSP VOR/DME instead. It's close enough for this exercise.

Anyhow, it's incomplete for now until I figure out how to build the odd-shaped bits but who knows, maybe somebody will find it useful even as a work in progress.

For now, I'm going back to studying aerodynamics.
