Which of the following is not crash protected?

The quick access recorder

The flight data recorder

The cockpit voice recorder

The combined voice and data recorder

  • A.The quick access recorder
  • B.The flight data recorder
  • C.The cockpit voice recorder
  • D.The combined voice and data recorder

Answer: A

Correct answer: The quick access recorder

The quick access recorder sits in an ordinary avionics enclosure, which is exactly what makes it quick to access. It exists for routine flight data monitoring, where the data is downloaded after every flight, and armouring it would defeat the purpose.

The other three are all crash protected, with the memory module in a hardened container that must survive impact, crush, penetration, fire and deep immersion in sequence. The combined unit simply holds both recordings in one such module.
