The reader of these transcripts is cautioned that the transcription of a CVR tape is not a precise science but is the best possible product from a group investigative effort. The transcript, or parts thereof, if taken out of context can be misleading. Therefore, the CVR transcripts should only be viewed as an investigative tool to be used in conjunction with other evidence. Conclusions or interpretations should not be made using the transcript as the sole source of information.
Furthermore, this transcript is made available for educational purposes, so the reader is encouraged to read the accident description associated with the transcripts for better understanding of the circumstances.
