Foreign acceptance of GPS.
I am non certain whether this is the correct forum to post my question on, but it seems to be the closest one that I can find.
After many years of the availability of "free" GPS coverage worldwide, and the proven successes of GPS approaches in a number of countries, I am puzzled on why the acceptance has not been more wide-spread in other countries, particularly poor countries, as a valuable tool to enhance air commerce and improve aviation safety.
In particular, I am talking about the rareness of GPS instrument approach procedures. While obviously not always the most prefered type of approach, the obvious benefactor would be the numerous airports which are not served by any type of an instrument approach at all. It seems to me that a Government-established procedure is still better than no procedure at all and also better than "home cooked" procedures.
Any thoughts on this?
