ChristianJ;
The continuous data stream into the FDR includes far, far more parameters
Depending upon the data frame programming, up to 40,000 parameters are available on later types but realistically, between 2000 and 3000 parameters can be done in a FOQA Program. DFDRs typically capture between 300 and 1000 parameters at varying sample rates. QARs, (optical disc, PCMCIA card etc) will almost always have higher sampling rates than DFDRs which for some parameters, ('g', control stick position etc) increases the usefulness - just like a strobe-light going off at ten times a second is more useful in a dark room than once every 4 seconds...QED.
I am aware from others' contributions of some technologies which can transmit such data on available satellite bandwidths which have been touted as "cost effective". Trouble is, I haven't seen the boxes and I have already commented on the
Aeromechanical Services solution on the Tech Log thread. The security of the data is paramount and so far, no one advancing these "solutions" has broached or discussed the topic.
