If im hovering say 2 meters and then something goes under it will it rise to avoid it because its to close ?

Try it lol, yes a simple way to test this is just put the palm of your hand underneath, be careful when testing this.

Hi there, thank you for reaching out and with regards to your question actually yes it will rise/climb the Aircraft and you will be notified from the App as well but make sure you enable the vision positioning.

I guess it depends on what is moving under the AC and how close it is. For example: if you place your hand underneath, the AC will rise.
