A couple years ago my company contracted to have all of our Special Use approaches in the region to be updated by a new company and I had to go fly a couple of them with the guy who was validating them. It wasn't a complicated process, but kind of interesting to watch. Since the approach wasn't valid, it wasn't in the data base so I had to build the approaches manually in the GPS (a laborious process on the legacy Garmins). Then we'd fly an approach with his laptop out that validated our actual position. He would also look for obstacles that may have been missed (which happened) and then notate them in his software.
The end product was light years ahead of what we previously had, to include having actual weather mins and not having to do the mental math of subtracting nearby field elevation from the pad elevation and then carrying the one and then...inevitably screwing it up. Basically it was a much more professional end product.
