I’ve been flying some large loiter circles and noticed that the plane is flying consistently larger than radius set in WP_LOITER_RAD. It’s the same behavior in the field and in SITL. Same in Loiter or Guided. I’m playing with radius between 200 and 400m, so this is not a tuning performance issue.
The image below is a 300m radius, however the plane is flying 360m. WP_RADIUS is 2m. Default quad-plane (stable FW) SITL.
This isn’t a big issue for me, I’m just more curious about the behavior and why the plane is doing it.
