Well, actually there are lots of folks who use gps units to make precision approaches to airfields now. My brother is the FBO manager at a small airport in the north GA mountains. One day he heard a plane call in to ask about the weather. It was raining cats and dogs. A short time later he heard a plane fly over at about 500 feet. A few minutes later the plane taxied up to the ramp and a good friend he recognized as a local pilot got out. He asked him if he was crazy and he said his gps was all he needed along with being familiar with the airfield and surrounding area. Some of the newer planes with the Garmin 1000 instruments are absolutely incredible with the detailed 3D display they can give you. It is much more precise than an ILS setup.
