Red: CH2 (Throttle); Green: Target Altitude
This is a Log from my last flight, where I was using a downward facing rangefinder.
Now, in Loiter mode the altitude hold was not to good and while browsing the logs for a reason I was wondering why the Target Altitude Changes without any RC input. Maybe somebody can explain to me what this TALT actually is?
Oh I see, I got that wrong. Thank you for the clarification!
Let me try again: DAlt - Desired Altitude
Now on this graph you can see again the Throttle (Green) but this time DAlt (Blue). For comparison I also put in DSAlt Desired Sensor Altitude (Red). (The log is from the same day as the last one.)
As you can see, at constant throttle DSAlt stays constant as well but DAlt does not. Why is that so? What could make DAlt change it’s value?
