Re,
but the EPR and ENG VIB give a better picture.
Thanks TP - (the VIBs are also ev. 4 seconds).
Typical FDA/FOQA QAR installations record FF at once-per-second, which speaks more to the need for finer granularity for DFDRs.
That said, it would be nice to have had the N1's here - they're there on the DFDR I'm sure, but don't know why they're not included in these traces.
