AT A FOREIGN ARPT THE FLC OF A MIL C130 TAXIED INTO POS ON THE RWY AND HELD CONTRARY TO THE ACTUAL TWR INSTRUCTIONS OF 'CLRED ON FOLLOWING THE LNDG TFC.' THIS CAUSED THE TWR TO SEND AROUND A B727 ON FINAL.

Narrative

PROB AROSE DUE TO A MISUNDERSTOOD 'CONDITIONAL CLRNC' RESULTING IN A RWY CONFLICT BTWN US AND A LNDG B727. THE CLRNC AS WE PERCEIVED WAS 'CLRED ONTO THE RWY TO WAIT FOLLOWING ACR X' (ACR X BEING THE ACR THAT WAS BEGINNING ITS TKOF ROLL). TFC ON A 5-8 MI FINAL WAS OBSERVED BUT THE THOUGHT WAS THAT WE WOULD RECEIVE AN IMMEDIATE TKOF AND WE READ BACK THE CLRNC AS WE HEARD IT. UPON SEEING THE ACFT IN FRONT COMMENCE HIS DEP TURN; TWR WAS QUERIED FOR TKOF CLRNC. AT THAT TIME HE INFORMED US THAT WE WERE 'CLRED ON FOLLOWING THE LNDG TFC.' WE ASKED TO CLR THE RWY; WHICH HE DENIED AND SENT THE B727 AROUND. CONTRIBUTING FACTORS: LANGUAGE PROBS COUPLED WITH PROBLEMATIC VHF RADIO. NOT ONLY DO THE CTLRS AT EL DORADO INTL SPEAK ENGLISH WITH AN ACCENT VERY HARD TO UNDERSTAND; BUT WE ALSO HAD A DEGRADED VHF ON OUR MIL C130E (ONLY EQUIPPED WITH ONE) AND THERE WAS NO UHF CAPABILITY AT EL DORADO. WE ARE NOT ACCUSTOMED TO THE ICAO CONDITIONAL CLRNC AND HAD NOT GIVEN FORETHOUGHT TO THE HAZARDS INVOLVED. HAD ANY OF THE CONTRIBUTING FACTORS BEEN ELIMINATED THIS OCCURRENCE WOULD LIKELY NOT HAVE OCCURRED. IT IS VERY HARD TO ELIMINATE THE LANGUAGE BARRIER. I WILL CONTINUE TO PUSH FOR A SECOND VHF RADIO IN OUR UNITS C130 (WITH NEW VIGOR AND WITH ADDED JUSTIFICATION). THE CONDITIONAL CLRNC HAS BEEN IDENTED AS A PROB IN THE PAST (AS I UNDERSTAND). LET THIS BE MY VOTE AGAINST SUCH A CLRNC. I SEE VERY LITTLE TIME SAVED VERSUS THE HAZARD INVOLVED. ALTHOUGH IN THE VMC CONDITIONS WE HAD ELIMINATED MUCH OF THE SAFETY HAZARD; IT MAY HAVE CONTRIBUTED TO ITS USE AND RESULTED IN A HAZARD AND A GAR FOR THE LNDG TFC.
