Narrative:
Forced by air carrier to depart on route from rplb (sfs) to osaka rjbb (kix) with both HF radios inoperative. Due to experience area on route sfs via direct cabin attendant R597 8ar81 A582 elmas - bisig and the fir (N4HA rorg fir) could have blank VHF communication, and therefore require HF. However, air carrier maintained route would be total VHF communication. Flight departed with heavy pressure from company operations that the route did not violate MEL MD11. It is vague to guarantee this communication requirement, therefore, I am writing this report. Flight operated without incident. However, HF radios did operate normal and were utilized after waypoint sarsi - elmas to bisig on A582 to fir. Naha VHF at fir was good.

Title: MD11 CREW WAS REQUIRED TO OPERATE THE FLT WITH MEL INOP HF RADIOS ON A RTE REQUIRING HF RADIO COM.
Narrative: FORCED BY ACR TO DEPART ON RTE FROM RPLB (SFS) TO OSAKA RJBB (KIX) WITH BOTH HF RADIOS INOP. DUE TO EXPERIENCE AREA ON RTE SFS VIA DIRECT CAB R597 8AR81 A582 ELMAS - BISIG AND THE FIR (N4HA RORG FIR) COULD HAVE BLANK VHF COM, AND THEREFORE REQUIRE HF. HOWEVER, ACR MAINTAINED RTE WOULD BE TOTAL VHF COM. FLT DEPARTED WITH HVY PRESSURE FROM COMPANY OPS THAT THE RTE DID NOT VIOLATE MEL MD11. IT IS VAGUE TO GUARANTEE THIS COM REQUIREMENT, THEREFORE, I AM WRITING THIS RPT. FLT OPERATED WITHOUT INCIDENT. HOWEVER, HF RADIOS DID OPERATE NORMAL AND WERE UTILIZED AFTER WAYPOINT SARSI - ELMAS TO BISIG ON A582 TO FIR. NAHA VHF AT FIR WAS GOOD.
