Pre-flight: No ADC vars at startup Software group was able to sort out before takeoff.
Flight: 16:58 - lost DPs, VCSEL, and QCFR, and TAS_X after takeoff. - QCFR outage reported to be due to broken line. 17:03 - reset DPT and DBP with no result 17:35 - res et nimbus after software var change. 17:40 - lost all TEMP DAQ housekeeping vars. drops correspond to PPS error on status page for ttyCTI0 on DSM 321. - recovers sporadically throughout flight 18:16 - reset satcom 18:39 - reset nimbus for software change to PSFC. Fixed DP / VCSEL dropout issue.
QCFR was known down before flight. This rippled through many derived variables. It took two attempts at mods to the DependTable and restarts of nimbus to get it all. This was a switch from right pitot-static to radome pitot-static (QCFR to QCR).
