Module 4 will now look at the electronics or better known as “black boxes.” It’s evidence for data collection. It’s field collection and a lot of it is recorded. It
could be the FDR, the CVR, or air traffic control recordings.
What you’ll do in this discussion area is you’ll pick two FAR 121 accidents. Again, it could be from the ASIAS or the NTSB. You need to discuss the similarities
and the differences that may have challenged the investigations. Then, you need to compare and contrast data that came from the good and old CVR, FDR
and ATC recordings. You will need to identify some of the challenges in collecting from crash sites or other places.
You need to know how important electronic evidence is in determining the cause of an accident.
Pick any two Federal Aviation Regulations (FAR) Part 121 accidents from the Aviation Safety Information Analysis and Sharing Program (ASIAS) or the
National Transportation Safety Board (NTSB) website and contrast the accident reports. Focus on similar or different challenges presented to the accident
investigators during their field investigation and evidence collection based on crash site differences.
Using the same two accident reports you picked above, compare and contrast the information collected from the Cockpit Voice Recorders (CVR), Flight Data
Recorder (FDR), Air Traffic Control (ATC) Recordings, and other electronic media in the accidents. What challenges were there in collecting electronic
evidence? How important was electronic evidence in determining the cause(s) of the accidents?
