If you think mastering the user interface of an approach-certified TSO C129 GPS is tough, just try getting a new GPS approach! Case in point: the new GPS-A approach at Driggs, Idaho, a popular fly-in destination on the western edge of Grand Teton National Park. In this article, an aircraft owner and pilot based at Driggs documents his incredible two and a half year struggle to get a GPS approach commissioned, published and flyable. Believe it or not, getting the FAA to design and approve the approach turned out to be the easy part! Persuading Garmin to fix their software so it will recognize the approach turned out to be the real stumbling block. Is the ordeal over yet? Hard to tell.
