Narrative:

Our IFR clearance out of osaka-kix was kec-ai-miyakejima- organ-renau-OTR17-ferar-mason-milva-N3400.0/E17000- N3100.0/E18000-N2700.0/W17000 syvad. This is what I read back. However, N3200 was skipped in either initial clearance from ATC or in my readback but was never corrected. Therefore we were going direct from N3400.0 to N3100.0, instead of veering to the north to the N3200.0 position. After N3400.0 were re-issued clearance to N3200.0 coordinate. Supplemental information from acn 316951: clearance delivery issued a re-route, which first officer copied and read back twice. Clearance delivery rogered readback. In-flight, ATC asked us to confirm routing (in non-radar environment, our position reports must have clued them in.) routing read back, and ATC revised clearance to include a coordinate originally shown on our first flight plan. Due to lack of automation in this cockpit, pre-departure is a hectic time anyway, what with loading INS's and fuel checks and performance calculations and required briefings and last-minute maintenance. The cockpit environment, and the obvious language problems, contribute to poor communications. It is possible no error was made here, but the point is more that, despite the efforts of a very conscientious crew, mistakes are possible.

Title: NAV DEV.

Narrative: OUR IFR CLRNC OUT OF OSAKA-KIX WAS KEC-AI-MIYAKEJIMA- ORGAN-RENAU-OTR17-FERAR-MASON-MILVA-N3400.0/E17000- N3100.0/E18000-N2700.0/W17000 SYVAD. THIS IS WHAT I READ BACK. HOWEVER, N3200 WAS SKIPPED IN EITHER INITIAL CLRNC FROM ATC OR IN MY READBACK BUT WAS NEVER CORRECTED. THEREFORE WE WERE GOING DIRECT FROM N3400.0 TO N3100.0, INSTEAD OF VEERING TO THE N TO THE N3200.0 POS. AFTER N3400.0 WERE RE-ISSUED CLRNC TO N3200.0 COORDINATE. SUPPLEMENTAL INFO FROM ACN 316951: CLRNC DELIVERY ISSUED A RE-RTE, WHICH FO COPIED AND READ BACK TWICE. CLRNC DELIVERY ROGERED READBACK. INFLT, ATC ASKED US TO CONFIRM ROUTING (IN NON-RADAR ENVIRONMENT, OUR POS RPTS MUST HAVE CLUED THEM IN.) ROUTING READ BACK, AND ATC REVISED CLRNC TO INCLUDE A COORDINATE ORIGINALLY SHOWN ON OUR FIRST FLT PLAN. DUE TO LACK OF AUTOMATION IN THIS COCKPIT, PRE-DEP IS A HECTIC TIME ANYWAY, WHAT WITH LOADING INS'S AND FUEL CHKS AND PERFORMANCE CALCULATIONS AND REQUIRED BRIEFINGS AND LAST-MINUTE MAINT. THE COCKPIT ENVIRONMENT, AND THE OBVIOUS LANGUAGE PROBS, CONTRIBUTE TO POOR COMS. IT IS POSSIBLE NO ERROR WAS MADE HERE, BUT THE POINT IS MORE THAT, DESPITE THE EFFORTS OF A VERY CONSCIENTIOUS CREW, MISTAKES ARE POSSIBLE.
