I’m using an mRo Pixracer, Arduplane 3.8.5 and Mission Planner 1.3.56.
In the beginning of a flight I launch in MANUAL mode and check the airplane to make sure it feels right and the systems are responding normally. Then I switch to AUTO mode to start a pre-programmed mission plan. Does the mission begin at the waypoint nearest to the airplane at the moment I switch to AUTO? Or, does the mission always start at the first waypoint?
I often abort a landing by switching to MANUAL mode. Then I fly another approach. Then I switch back to AUTO when I’ve got the airplane back near to the final approach leg. The airplane usually resumes the auto-landing. I believe this is because when the abort is triggered by a switch to MANUAL mode the mission will go back to the DO_LAND_START if I switch to AUTO again. Is this correct?
The reason I often have to abort a landing is because the airplane is overshooting the landing spot. The only time I came close was when I set the TECS_LAND_SPDWGT to -1. The airplane was forced down and landed near the spot but did not flare. I tried the same plan but with the TECS_LAND_SPDWGT set to 0.67 and it overshot by 200 feet again. I’m using an airspeed sensor and that seems to be working well and I have reasonable land and pre-flare airspeeds set for this particular airframe. Glideslopes are all between 3 and 7 percent when on base leg and final. What else can I try to get a nice flare closer to the landing spot?
