Narrative:
ATC clrncs and high terrain in south america. We were flying into call columbia when ATC cleared us direct to the cali VOR and descend to 5000 ft. Cali has a STAR and high terrain of either side of the STAR routing. When I checked the points on the STAR against our current direct the VOR route of flight it looked like we would be very close to the STAR routing. When you are 200 mi out, a 15 mi difference is barely noticeable. Further checking of the area chart and our direct the VOR routing showed terrain at 14000 ft to 11000 ft directly along our path. A similar ATC clearance happens very often flying into lima, peru. Many, many, many pilots are not aware of just how crucial it is not to accept these deadly clrncs. Please get the word out again.

Title: MINIMUM ALT ASSIGNMENT POLICY -- THE ATC PERSONNEL AT THIS FACILITY (FO) WILL OFTEN ASSIGN ALTS TO ACFT OFF-RTE THAT ARE BELOW INTERVENING TERRAIN.
Narrative: ATC CLRNCS AND HIGH TERRAIN IN SOUTH AMERICA. WE WERE FLYING INTO CALL COLUMBIA WHEN ATC CLRED US DIRECT TO THE CALI VOR AND DSND TO 5000 FT. CALI HAS A STAR AND HIGH TERRAIN OF EITHER SIDE OF THE STAR ROUTING. WHEN I CHKED THE POINTS ON THE STAR AGAINST OUR CURRENT DIRECT THE VOR RTE OF FLT IT LOOKED LIKE WE WOULD BE VERY CLOSE TO THE STAR ROUTING. WHEN YOU ARE 200 MI OUT, A 15 MI DIFFERENCE IS BARELY NOTICEABLE. FURTHER CHKING OF THE AREA CHART AND OUR DIRECT THE VOR ROUTING SHOWED TERRAIN AT 14000 FT TO 11000 FT DIRECTLY ALONG OUR PATH. A SIMILAR ATC CLRNC HAPPENS VERY OFTEN FLYING INTO LIMA, PERU. MANY, MANY, MANY PLTS ARE NOT AWARE OF JUST HOW CRUCIAL IT IS NOT TO ACCEPT THESE DEADLY CLRNCS. PLEASE GET THE WORD OUT AGAIN.
