What I mean is: Being unable to abort AND holding throttle down coming from altitude. Both were not an issue in the earlier firmware. maybe the newer firmware messes op logic giving manual input (holding throttle down) higher priority than VPS data and completely disregarding data from the ultrasonic sensors saying that the aircraft is NOT in landing position. I personally think nothing wrong with the sensors, just monkey programming.
Well, I believe the issue of Mavics going into auto-land at high altitudes has nothing to do with software changes. The software logic has been the same since the beginning. Basically "If VPS height is less than or equal to 0.5m, and throttle is held down for 3 seconds, then initiate auto-landing." The only thing that causes Mavics to incorrectly enter auto-landing at altitude is a faulty reading or interpretation from the VPS ultrasonic sensors. I personally believe those Mavics with this issue have faulty ultrasonic sensors. DJI released a "fix" for the problem in the newer firmwares, but it seemed more like a workaround than a real fix. And several people who had this VPS issue still had the issue even after the firmware fix, and ended up having to send their Mavics back, anyway. |
