titleData & Data Analysis
  • houston cold battery endurance time: 8 min

  • temp today: 3 degree outside

Expand
titleWhat Went Well?
  • good logsitic solid plan

  • Houston still in one piece

  • Battery got charged and discharged

Expand
titleWhat was less than ideal but turned out okay?
  • we figured out the cold battery is not enough to complete auto tune even with one axis

  • pegasus is not ready in advance

    • sensor not plugged in

    • not knowing how to set up LTE

  • Takeoff in stabilize once and pilot wasn’t aware

    • that leads to a crush- didn’t break anything tho

  • Houston battery performance were greatly affected by cold temperature

Expand
titleWhat major issues occurred?
  • We lost the flight logs by accident

  • Pegasus bullet connector fails

    • the insulation of the wire got rip off

All of these major issues should be addressed via Root Cause Analysis Forms:

titleAction Items Following Test

Daniel Puratich Directing this section of flight test post mortem!

  •  Nathan LTE lesson - teach more ppl how to set it up
  •  consider battery heater
  •  Fixing pegasus motor bullet connectors
  •  reconsideration of wiring inside arm, it is ripping the insultaion
  •  Daniel Puratich will make an example of good bullet connector
  •  Daniel already emailed about the golden ring spacer for pegasus prop
  •  labelling the rangfinder and ofs connector
