Assertion (A): A quick access recorder does not satisfy the mandatory recorder requirement.

Reason (R): It is not crash protected and would not survive an accident.

Select the correct answer from the options below.

  • A.Both A and R are true, and R is the correct explanation of A
  • B.Both A and R are true, but R is not the correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true

Answer: A

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the second is precisely why the first holds. The mandatory requirement exists so that data survives an accident, and a recorder in an ordinary avionics enclosure would not.

The QAR records the same parameters and is fitted almost universally, but it answers a different question - what is happening across many flights - and its accessibility is the whole point of it. Recording the right data is not sufficient; surviving to be read is the requirement.
