You answered yourself why it is dangerous. Not necessarily for you or me but for others who may not be so cognizant of how the altimeter is used for RTH. Imagine someone putting in a RTH height of 100 feet when their altimeter is off by -100 feet. Is it really that hard to see the danger of crashing? I am not having angst over this. My altimeter is off by less than 10 ft after it is warmed up.
I received a new Vision+ V3.0 on Monday but it looks like I have a faulty barometer.
When turning it on at home the DJI Vision app altitude immediately starts counting down and eventually stabilizes around -2000 feet after several minutes.
I flew for the first time yesterday not realizing what problems this could cause. The outside temperature was about 48 degF and I took off when the altitude showed about -433 feet. I started testing Return to Home when the altitude showed about -375 feet and it looks like it started first to climb to altitude zero feet and then higher to the RTH height. I stopped the Return to Home pretty quickly since this was my first flight and was able to land normally.
Following is a screen capture shortly after starting Return to Home.
Anything I should do before returning it? FYI the Vision+ I received on Monday has a serial number PH645497XXX from Amazon.
