Wrong on all counts.
You asked me what the t1-t5 timing is for the ARINC 717.
I posted the link to the PDF, and also a link to the timing chart.
That information fully supports and answers your timing question.
The timing diagrams also shows the refresh of the buffer on ever
poll cycle.
That information totally blows your "old 2-6 second info" ASSUMPTION
out the window.
The other links and ARINC 717 PDF documents, aside from L3's e-mails
and voice call to ED Santana also support the <=500 msec timing from
sensor to CPM.
Three of your claims have been proven wrong.
Would you like to discuss data transfer, ARINC 717 and FDR over the phone
in real time so I can hear you babble and fumble your way through a scentence?
Man enough?
And if the FDR loses power. Or even if the sensors lose power. Even intermittently Then what?

A. Statement of the Problem
For many years, the National Transportation Safety Board (NTSB) has
experienced difficulties while investigating aircraft accidents and
incidents. The information recorded on cockpit voice recorders (CVRs)
and Digital Flight Data Recorders (DFDRs) has not always been
sufficient to support the NTSB's investigations. The problems
encountered by the NTSB include the limited duration of CVR recordings
preceding an incident, and the loss of power to both CVRs and DFDRs.
These issues arose in the investigation of the following accidents and
incidents: Alaska Airlines, Inc. flight 261 on January 31, 2000;
EgyptAir flight 990 on October 31, 1999; Delta Air Lines, Inc. flight
2461 on December 15, 1998; Swissair flight 111 on September 2, 1998;
SilkAir flight 185 on December 19, 1997; ValuJet Airlines flight 592 on
May 11, 1996; Trans World Airlines, Inc. flight 800 on July 17, 1996;
and ValuJet Airlines flight 597 on June 8, 1995. The notice of proposed
rulemaking that preceded this final rule was published on February 28,
2005 (``Revisions to Cockpit Voice Recorder and Digital Flight Data
Recorder Regulations,'' 70 FR 9752) and discusses these accidents and
incidents in more detail, starting on page 9753.
