Several Points...
Magplug and others...
A non-precision approach is just what it says..."non-precision"...The whole idea is to descend safely to an altitude from which the runway can be seen and a safe landing accomplished...
After passing the FAF, basic instrument skills (no FMS, just time, speed, distance) apply...descend to MDA and fly the course until arriving at the MAP or the runway enviornment becomes visable. Land or go around as appropiate...
These approaches are in widespread use in Africa and the Mideast...any pilot flying in these regions knows the drill and can practice it, or they have no business in this business...
As for the quote re: "without radar assistance..." this a/c most likely was under ATC control during the approach...how else could ATC have mandated a "missed approach" thus "preventing a crash"?
