I flew jets (727's and A310's) in a South American, very third world country for 25 years doing high density airport operations, NDB and step down VOR approaches at high elevation airports with very poorly designed CAA approach charts that left me with nothing but grey hair and an bad attitude, but when GPS came out of the blue sky, I was involved in the design of GPS approach charts for all those runways along with this foreing US company that provided us with company taylored charts. My company invested heavily on cockpit CMA900 GPS/FMS equipment to be used with this new technology. Thinking that this would really improve the safety record in my airline and that all those white knuckle approaches were over....guess what? WRONG!!!! like you guys mention, I had to struggle with the local system, first to approve the WGS84 Datum system which my beloved country did not approve until recently, why? because the military Geodesic Institute was in charge and they wanted a big piece of the action (Money), then the authorities (DGAC) formed the most outrageous bureaucratic process imaginable where every one wanted money. "Corruption" is the only reason I can imagine why those poor third world countries don't come out ahead, no matter what you give them, even if its free!
