Dear users,
I’m using Arduplane V4.0.2 in a Pixracer 15.
Yesterday during a CRUISE flight the plane suddenly lost altitude while at the same instant I saw the altitude reported by Mission Planner had grown by about 70 meters.
Fortunately there were no consequences having immediately taken manual control of the model.
Analyzing the logs at the time of the fact I see that GPS.alt and BARO.alt correctly report the altitude values during the bad moment, therefore the cause must be sought elsewhere.
In particular AHR2.alt at the moment of the problem detects a short glitch of considerable amplitude; being just a glitch it normalizes after a fraction of a second.
However the value POS.alt and NTUN.AltErr remain largely erroneous in for 4 seconds.
Here is a the log https://easyupload.io/6pl9py and the bad moment is at 14:11:12.498
I would be very grateful if anyone could take a look at the log at that time.A cordial greeting to all
