It is a known fact that CFIT risk is increased significantly with a non precision app . This particular proc . is more difficult than the average especially when the last time I did it ATC wanted 180 kts to 4 miles . That said it may not be attributed to CFIT but there is no doubt that a VOR/DME in these conditions at night into an a/f with high terrain would have increased the workload with a consequential reduction in situation awareness which in turn means that any other additional problem encountered eg wx tech fault atc or even ice could catch of any of us out at some stage .
This app whilst reducing noise does increase the risk .
