Select the correct match.
Answer: B
Correct answer: A-1, B-2, C-3, D-4
Each device answers a different need. The data recorder holds aircraft parameters over a long period and the voice recorder holds speech, radio calls and ambient sound - together they give what the aircraft did and what the crew said and heard.
The underwater locator beacon guides the search with an acoustic pulse. The quick access recorder holds a removable medium for routine safety monitoring, and it is the only one of the four not concerned with accident investigation at all.
