💻 DEBRIEF

Flight test debrief report

Before Card 1:

Before departure

Yuchen Lin didn’t logistic going to flight test → next time book the car beforehand + long weekend machine shop does not open

Yuchen Lin Hardy Yu Testing with huston → connected to mission planner and able to forward the message(test 2 times)

  • first one does not flash the latest code

  • second one see tracking antenna working as expected

After departure

pre-flight tracking antenna testing: (no code change)

Keep rotating without stop and does not work

After adjust to the north keep rotating clockwise

does not help after adding delay

 

Card 1 Test 1

Info

Flight planning

  • conduct half task 1 goal (1.5 lap)

Flight test card requirements/objectives Performance

  • Comp sim

Panel
bgColor#E3FCEF

Control performance & payload situation

  • Four payload in the cabin + alien key

  • Hardy Yu manually track the drone

Note

Identified issue

  • Compass variance issue

  • place the drone backward and cause sharp turning

Warning

Issue need to be RCA

  •  Gemini not working (performance worse than without gemini) → fully lost link

    • Link quality got worst after first lap

    • possible thermal issue

    • flew lost link 750 meter

    • previously tested with the same gemini board with smaller antenna with 3km

    • gemini is not hot at all

    • look at power used(power limit)

 

Card 1 Test 1 retry 1

Info

Flight planning

  • conduct half task 1 goal (1.5 lap)

Flight test card requirements/objectives Performance

  • Check tuning in all three mode and compass variable at full throttle.

Panel
bgColor#E3FCEF

Control performance & payload situation

  • Four payload in the cabin

  • Current draw pretty good at calm weather

  • half of task 1 5000mah

Note

Identified issue

  • aggressive takeoff

  • Almost all the time ekf yellow

Warning

Issue need to be RCA

  •  

 

Card 2 Test 1

Info

Flight planning

  • Test the auto mission task 2 pathing and training pilot for landing

Flight test card requirements/objectives Performance

  • During flight time upload the mission to pixhawk

  • Arm in auto and complete the mission

  • Pilot navigate through and land on the pad with fpv goggle

Panel
bgColor#E3FCEF

Control performance & payload situation

  • Four payload in the cabin

  • GSO and pilot get familiar with callout (Better callout procedure for less than 1 meter → with range finder) practice next week

  • cannot really callout the height sub 1 meter

  • easy to land on the paved ground

  • all the landing are smooth and within timeframe

  • descent first

Note

Identified issue

  • Daniel Puratich callout at last waypoint based on height not ardupilot

  • Full path does not show outside of planning window

Warning

Issue need to be RCA

  •  

 

Overall performance and Lessons learned

Outcomes

  • confident in flight characteristics of the drone and electrical robsutness

    • spline waypoints looked good during flight but looks poor on mission plannre

  • low confidence in custom rf links and tracking antenna

    • not using tracking antenna for comp → cc Daniel Puratich to bringup at AEAC

    • Gemini board was low link quality

      • try another gemini board and see if it works

  • Nathan Green apply new mag fit data based on today’s data

Check weather before comp.

Flightline tasks:
bring vtx tower, drone(path uploaded, battery in , shourds on), controller and the monitor

Before takeoff

Daniel Puratich conduct the pre takeoff checklist

manually toggle safety switch

confirm take off flight mode

arm in auto
