COCKPIT VOICE RECORDER TRANSCRIPT

The method used to transcribe the recording consisted of faithfully reproducing, almost phonetically, what was heard, without interpretation or extrapolation.

This was why several aircrew who knew the voices of the crew, the background noise of a Concorde cockpit and the various alarms joined in with this work. In addition, filtering adapted to the flight segment allowing reduct"n of the parasite background noise was used to improve the intelligibility of the recording.
