The 1:1 rule for safe distance from people

In plain language

Always maintain a horizontal distance from uninvolved people that is at least equal to your current flying height (for example, stay 20 meters away horizontally if you are flying at a height of 20 meters).

Requirement as structured

When flying near people, the remote pilot should maintain a horizontal distance from any uninvolved person that is at least equal to the drone's current flight altitude.

Original regulatory text
