What about the QAR?
QAR data have been helpful in crash investigations before: Strasbourg for example, where the FDR itself was destroyed by fire, or Gonesse, where the QAR recording medium was more conveniently accessible (optical disc vs. magtape).
The interim report mentions only the CVR and FDR models installed on AF 447 (Honeywell 6022 and 4700, respectively), nothing about the QAR. Does anyone know what kind of device that might have been?
