A quick access recorder differs from a crash protected recorder in that it

  • A.Is required by regulation on all aircraft
  • B.It is not crash protected
  • C.Records voice rather than data
  • D.Has a longer retention period

Answer: B

Correct answer: It is not crash protected

A quick access recorder holds the same data stream but in an ordinary enclosure, easy to reach and to download. It exists for routine flight data monitoring, not for accident investigation, so it needs no armour.

That is what makes it useful: the crash-protected recorder is deliberately difficult to access, and downloading it after every flight would be impractical. The QAR is not mandated by regulation, records data rather than voice, and typically holds a shorter period.
