An air carrier B757 flight crew had to make an instrument approach to runway 35 with a 12 KT tailwind due to a company policy. While on final approach another air carrier, a DC10, was on final approach to runway 17. The approach controller, apparently, attempted to have the reporter do a 360 degree turn to delay, but he used a company aircraft's call sign. The reporter made a go around and the other company flight crew refused to make the delay turn due to terrain clearance concerns.

Narrative:
Both company mia-uio flight arrived nearly the same time in uio. My flight was on final approach runway 35 with a 12 KT tailwind. Another aircraft, a DC10, was on short final runway 17. Continuous light occasional moderate turbulence in terminal area due winds. ATC requested our other flight (flight Z) to a 360 degree heading, thinking he was us. Flight Z was confused as this would put him in the rocks. The other flight (Z) was starting approach over qit VOR. Ensuing chaos was very undesirable as flight Z argued with ATC, we could not land due to DC10 and on account of turbulence on our second approach. ATC was totally screwed up with the 2 call signs for quite a while. Eventually we all landed ok, but...this captain believes tailwind lndgs at uio are far more hazardous in some WX conditions than making a visual approach to runway 17. It's dumb to tie the hands of a pilot with silly policies like this. Dumb. Yee-hah...more south american adventures next week.

Title: AN ACR B757 FLC HAD TO MAKE AN INST APCH TO RWY 35 WITH A 12 KT TAILWIND DUE TO A COMPANY POLICY. WHILE ON FINAL APCH ANOTHER ACR, A DC10, WAS ON FINAL APCH TO RWY 17. THE APCH CTLR, APPARENTLY, ATTEMPTED TO HAVE THE RPTR DO A 360 DEG TURN TO DELAY, BUT HE USED A COMPANY ACFT'S CALL SIGN. THE RPTR MADE A GAR AND THE OTHER COMPANY FLC REFUSED TO MAKE THE DELAY TURN DUE TO TERRAIN CLRNC CONCERNS.
Narrative: BOTH COMPANY MIA-UIO FLT ARRIVED NEARLY THE SAME TIME IN UIO. MY FLT WAS ON FINAL APCH RWY 35 WITH A 12 KT TAILWIND. ANOTHER ACFT, A DC10, WAS ON SHORT FINAL RWY 17. CONTINUOUS LIGHT OCCASIONAL MODERATE TURB IN TERMINAL AREA DUE WINDS. ATC REQUESTED OUR OTHER FLT (FLT Z) TO A 360 DEG HDG, THINKING HE WAS US. FLT Z WAS CONFUSED AS THIS WOULD PUT HIM IN THE ROCKS. THE OTHER FLT (Z) WAS STARTING APCH OVER QIT VOR. ENSUING CHAOS WAS VERY UNDESIRABLE AS FLT Z ARGUED WITH ATC, WE COULD NOT LAND DUE TO DC10 AND ON ACCOUNT OF TURB ON OUR SECOND APCH. ATC WAS TOTALLY SCREWED UP WITH THE 2 CALL SIGNS FOR QUITE A WHILE. EVENTUALLY WE ALL LANDED OK, BUT...THIS CAPT BELIEVES TAILWIND LNDGS AT UIO ARE FAR MORE HAZARDOUS IN SOME WX CONDITIONS THAN MAKING A VISUAL APCH TO RWY 17.
