  1. RF07

    March 16, 2024

    Tech: Richard Freeman


    Taxi: 09:40Z

    Takeoff: 09:46Z

    Landing: 17:50Z

    Pre-Flight: 

    • 09:43Z - DSM325 time lag of 1-3 seconds observed on controls status page.
      • Rebooted DSM. Time lag remained
    • RSTT came up without issue.

    Flight:

    • Camera's failed to start. Firewire card "zombie" process appears to be the culprit. No in-flight solution possible.
    • 10:07Z - Another reboot of DSM325 was attempted with the same result.
      • Lag determined to be within acceptable margins by Catherine.
    • 11:29 Z - Power cycled PHIPs at Franzi's request.
    • 12:30Z / 15:30Z - Topped of dry ice reservoir at L9 rack.
    • 15:58Z → 16:18Z - ADIFR flooded during descent and ascent of cloud profile pass. Recovered afterward. CVI and SDI Inlets thought to be similarly impacted.


    • 2DC performed better than on RF06. Brief ~10 seconds drops noted on occasion. But no sustained outages. 


  2. Re: dsm325 time lag on control page - there is a line item somewhere, "crony tracking" I believe.  Updates slowly, every 11 or 17 seconds, that should tell you the DSMs real time offset.
