I flew 16 missions today using IOS Capture. After 6 successful missions, the next time, the P3P just started descending after the end of the mission. I had to take over and land the Phantom. I don’t think I got a mission complete message. I had to abort the mission to start the next one. This pattern continued for the next 4 missions. Luckily I was paying good attention the first time and I will also always do so now… On Mission 11, I shut everything down and started the mission like it was the first mission of the day. Now the P3P finished the mission, gave me a mission complete message, rose 25’ more feet to 125’ and returned home correctly.
We have been flying a lot lately and this behavior was unique for today. I had noticed that the P3P flies slowly to the start point but races back fast after the end of the mission so I usually put the finish at the far end of the project. I was doing a short street segment today and got lucky to notice the unusual behavior.
I am using an Ipad Air 2 with the latest version of Capture and with the latest versions of the Phantom 3 Pro firmware. I have a Maxx UAV antenna. I am currently flying city streets for Plan and Profile sheets for paving and drainage project.
Hopefully this behavior was random but it sure was scary.
