Just today I notice an altitude inaccuracy from start to finish, so I need to do some more testing to figure it out just what it going on.
When I launched a Litchi mission this morning, I had the first way-point set at 10'. When I enabled the mission, the craft went to the 1st way-point set at 10' AGL (I was on a cliff), and it did indeed start the first way-point at about 10' high, as expected. As I flew the mission I cancelled it. I wasn't happy with the route, so I started flying manually around the area collecting video for about 15 minutes. However, when I returned, flying manually, the elevation data on the screen got skewed somehow. When I returned to the original way-point #1 (manually flying to that location, very close to right above my head), instead of showing 10' high, it showed 50' high, when in reality it was only 10' high. Since it was 40' off, I'm thinking if I had finished the mission, during the return leg to the last way-point set at 10', it would have run into the cliff I launched from. This was 8am, it was about 85F, and getting warmer. I'm wondering now if heat skews the barometer accuracy.
I had never noticed this elevation anomaly before because I always flew WAY ABOVE ground level 150' or more, too high to discern any elevation inaccuracies of 40'. Has anyone else flying Litchi missions noticed this problem?
