Читать книгу Air Disasters: Dramatic black box flight recordings - Malcolm MacPherson, Malcolm MacPherson - Страница 4

After an accident occurs and the black boxes are located at the accident site they are pulled from the wreckage and quickly delivered to a laboratory where they are opened and examined. In America that examining agency, the NTSB, is located at L’Enfant Place, Washington, DC. To listen to the tapes a CVR committee is formed from the representatives of the airlines, the manufacturers of the aircraft and of its engines, pilots’ unions and the NTSB. This committee compiles a written transcript of the CVR to be used during the investigation, and examples of such transcripts, edited by the NTSB investigators, are what you are reading, for the most part, in this book. FAA’s air traffic control tapes, with their associated time codes, are used to help determine the local standard time of one or more events during the accident sequence. The transcripts, containing all pertinent parts of the recording, are edited. Anything other than factual information is removed in the knowledge that the transcripts very often contain highly personal and sensitive verbal communications inside the cockpit.
