🚩 Pre-flight Safety Checklist

 Pre-Flight Inspection
  • Air Frame
    • Check all antennas, ensuring they are secure and in good condition
    • Check the battery emplacement and secure attachment and ensure there are no cracks
    • Check that all lights are operating normally
    • Check that all sensors are secured and clear of any obstructions
    • Check that the GPS is receiving satellites and providing a navigation solution
    • For rotary aircraft:
      • Inspect top and bottom of air frame arms for cracks, loose parts, or signs of damage
  • Propellers / Rotors
    • Ensure propeller is secured
    • Check for nicks, chips or cracks
    • Ensure prop direction is correct
  • Batteries
    • Inspect to ensure there is no signs of swelling, external leaking or other defects
    • Battery wiring and connectors from the battery are connected securely
    • Batteries (and spares) are adequately charged
    • Wires are not pinched
  • Control Station / Receivers / Transmitter
    • The battery and spare batteries if required are adequately charged
    • Control Station device and cables are properly connected and functioning
    • All flight interfaces are functioning normally
  • Safety
    • Good visibility and safe wind speed
    • Surrounding is free of obstacles
    • Crew far from drone

Flight Test Post Mortem

  • Autopilot was swag

  • All systems functioned well (RTL, Land, etc)

  • Our RFD900x worked well

  • Battery lasted a long time (at least 8 minutes, exact time tbd)

  • Failsafe (Lost link) went to RTL

  • Roughly 600m range tested (though we had historically done a 3km test)

  • Nobody got hurt (physically or mentally)

  • We weren't rigorous in our testing methodology

  • It was difficult to view the ground-station due to glare and short usb-cable to antenna tower

  • Key to WRESTRC was forgotten and we had to go back

  • No safety briefing

  • Roles were not well defined

  • Timelines were not followed

    • and they were incorrect

  • Flight Controller configuration was not complete by the day before

  • Nothing was conformal coated

  • Houston was not registered and PIC phone number was not on the aircraft

  • Trusting the autopilot too much

    • not paying attention to the aircraft when near ground/people

  • No fire extinguisher

  • We messed up prop directions initially

  • The battery test was not added to the list of things to test

  • The entire premise of doing this RFD range test was misfounded

    • We had previously tested the RFD to 3km with worse antennas so the entire point of this range test was pointless

    • Last cornflakes (FrostedFlakes) flight test had an RTL

      • though this occurred when it wasn’t flying…

  • ZeroPilot PPM didn’t get tested

    • We wanted to test this but it wasn’t done in time

  • We crashed into snow and there was no liquid protection

    • Including RCA for crash

    • We did not know what to do when the crash occurred

  • Flight test didn’t validate anything

    • This flight test cost us a ton of money and didn’t validate anything

      • We didn’t test the ZP PPM

      • We didn’t test range (which was already tested)

    • Clearer flight test plan should have been done in advance

      • We made out 2km test waypoint mission on the spot
