When we got the first generation CAPSTONE equipment installed in our aircraft with the Apollo MX-20 MFD (not synthetic vision), I had a hell of a time NOT incorporating the screen into my instrument scan. In IMC, and even more so in white-out conditions, my eyeballs kept get getting drawn to it and tried to fixate. Drove me nuts, and several times I just pulled out the sticky pads and covered it up because I found myself waaaay behind the airplane with unintended big heading changes (I like using a heading up arc on the display settings). The once a second update rate on the display is way too slow for real time use.
However, once I figured it out, and slowly gained trust that the data programmers didn't cross their zeros and ones, and the GPS data wasn't going to ignore that ridgeline that was actually there, that box was magic. I had approaches into runway ends at all my strips, and the ability to tighten up the CDI to 0.01 mile and draw out a course line made for a localizer approach into all of them. Very cool stuff.
I left AK before the second generation equipment made it that far north, but a buddy of mine in Sitka says it's even better with the Chelton boxes. However, he warns that the box may get you down the the water in a 100 ft overcast, it won't see a 200 ft tall cruise ship right in front of you!
