With no moving parts, there are fewer maintenance issues and a decreased chance of something breaking during a crash.ĭata from both the CVR and FDR is stored on stacked memory boards inside the crash-survivable memory unit (CSMU). Solid state uses stacked arrays of memory chips, so they don't have moving parts.
Solid-state recorders are considered much more reliable than their magnetic-tape counterparts. Following any airplane accident in the U.S., safety investigators from the National Transportation Safety Board (NTSB) immediately begin searching for the aircraft's black boxes. That's why investigators turn to the airplane's flight data recorder (FDR) and cockpit voice recorder (CVR), also known as "black boxes," for answers. There are usually many unanswered questions when a plane goes down. The voice recorder should also provide the cockpit crew's voices, engine sounds, instrumentation warnings and other audio recording during the flight. According to reports from AP, the flight data recorder should help investigators get some answers about what caused the two-month-old Boeing 737 MAX 8 to crash just after takeoff.

The NTSB displayed Asiana Airlines flight 214 flight data recorder and the cockpit voice recorder in July 2013 in Washington, D.C.
