Difference in kinds of plot shown in PX4 log (online tool)

1

Hi, it’s my first time to post something on this forum.

I got logs of my flight test yesterday, and would like to analyze the result.
However I found that there are differences in kinds of plot shown in PX4 log (online tool)

flight 1
https://logs.px4.io/plot_app?log=fd941d79-d09e-414b-9c13-1ab6c38f3c77

flight 2
https://logs.px4.io/plot_app?log=463401ac-a862-4439-927b-ae6e9bda433b

I see “Airspeed” plot in flight 2 log, but there isn’t “Airspeed” plot in flight 1 log.

For flight 1 and 2, I did not change any hardware configuration nor parameters other than the cruise speed.

Can anyone tell me why contents are different like this?

Did you notice the ‘airspeed sensor missing’ warning? The warning is at the bottom of the log page. If it was there it wasn’t being detected for some reason.
