Well, chalk up another one to the limitations of sims. Today's return-to-launch (RTL) testing was a mixed bag. When the Superstar was heading off away from us and I enabled the autopilot, it nicely turned back, but when it got overhead it went into a death spiral and I had to disable the autopilot to recover. This happened multiple times, despite it working fine in the sim. Perhaps this was due to the wind (10-12 mph) or the airframe, but the software should be doing a better job regardless.
I think we need to work harder on our "circle overhead" algorithm and otherwise put a little more AI in our navigation routines. This is pretty normal for this stage of development and we'll get there. Meanwhile, it was nice to fly on another beautiful day in the Bay Area.
