You can fly an unmanned aircraft as far as you are able to see its orientation, and objects around it, with your own eyes.
You need to watch your unmanned aircraft yourself and not rely on binoculars, a monitor or smartphone. If something unexpected happens you need to be able to take immediate action to get your aircraft out of the way or land it.
