Cockpit Voice Recorder Transcript

The following is a transcript of the Fairchild model A-100A CVR installed on Korean Air flight 801 (a Boeing 747-300, HL7468), which crashed while approaching Guam International Airport on August 6, 1997.

The CVR transcript reflects the final 31 minutes 1 second of the accident flight. Times are expressed in coordinated universal time (UTC time), which is 10 hours behind Guam local time. Only radio transmissions to and from the accident airplane were transcribed. Items that were stated either partially or completely in the Korean language are shown as two entries. The first, in bold type, is translated into the English language. The second is typed as if it were spoken in Korean and/or English. Items with only one entry were spoken entirely in English.

I will give you a short briefing .. ILS is one one zero three .. NIMITZ VOR is one one five three, the course is six, when we are in the visual approach, as I said before, set the VOR on number two and maintain the VOR. for the TOD, I will add three miles from the VOR, and start descent when we're about one hundred fifty miles out. I will add some more speed above the target speed. well everything else is all right. in case of go-around, since it is VFR, while staying visual and turning to the right . . . , request a radar vector. if not, we have to go to FLAKE ... turn towards FLAKE ... turning towards a course zero six two outbound heading two four two and hold as published. since the localizer ground slope is out, MDA is five hundred sixty feet and HAT is three hundred four feet. it was a little lengthy. this concludes my landing briefing.

아, 간단히 말쑴드리겠습니다. ILS가 110.3,

  NIMITZ VOR 115.3, course 063, 시정 6 이라니까 visual 되면, 음. . (아까 이야기 했던대로.. . . 어- -, VOR NO 2 VOR 계속 set해 주시고. . .
