I was wondering if obstacle avoidance would kick in if it detects a moving object like a train approaching at close range that could potentially hit the low flying drone that was hovering to capture the moving train? Luckily, I was a foot or so above the locomotives, but wow, scary. I will never do that again. But it got me thinking about OA.
I’m guessing the answer is NO, and as a pilot keep your drone out of arms way of moving trains. Which is did, with about a foot to spare. If that.
