Also, most of this stuff is highly optional and it's stored mainly because it can be. 20 years ago standard FDRs on aircraft like the 777 had the capacity to record 64 or 128 words per second (0.77 or 1.54 Kbps). After the expansion of the list of required parameter groups in 2002, Boeing started installing FDRs capable of 3 Kbps.
Perhaps, but will it be Robust and Sustainable to be Fit For Purpose?
