Unfortunatly many A/C are flown in 3rd world countries who are not yet "modern".
It has little to do with the type of approaches. Non precision approaches have been normal procedure since instrument approaches were first used in aviation. This includes WW2. The problem is the incompetency of the pilots that fly them and the age old habits of `ducking` under. ` Change the attitudes, cultural or otherwise of the crews and the perceived risks associated with non-precision approaches will reduce.
"Real men don't go around" is the attitude that leads to crashes and kills people and there is plenty of evidence this attitude is common among certain types of pilots. Again, ethnic culture often plays its part.
