In plain language

If you are flying a medium drone and visibility drops to 4 miles or less, you cannot fly further away than half of whatever that visibility is (e.g., if visibility is 2 miles, you can only fly up to 1 mile away), unless you have an SFOC.

Requirement as structured

If ground visibility is four miles or less, a pilot must not operate a medium remotely piloted aircraft in VLOS at a distance greater than half of the ground visibility unless authorized by a Special Flight Operations Certificate.

Original regulatory text
