Hi everyone!
During Loiter, my throttle oscillates rather consistantly. The tuning graph suggests that APM is responding to airspeed (as opposed to altitude) because of the frequency of the oscillations and how it relates to my target alt.
If there were a PID for airspeed alone, I'd probably be able to make sense of it.. .maybe lower P and increase D a bit. However, i don't see such a loop for that particular aspect, so I'm a bit lost.
What would be the best way to smooth out throttle oscillations during loiter (and probably auto)?
i'm using the airspeed sensor (enabled) and while my alt is oscillating as well, it is doing so on a much slower rate--pretty sure that's the pitch/alt PID loop that needs work. This throttle thing seems separate.
Here is a clip of what the tuner shows me:

Hi,
If I may ask, what does the airspeed sensor installation look like?
Is the pitot tube installed in an undisturbed airstream?
I'm just curious because I need to install the one I've recently received from the store here. Thanks.

I know this one's a puzzler, but doesn't anyone else have this in operation on their plane?
