Distance Limit for Guide-Rail Tethered Flights

In plain language

If you tether your drone using a guide rail or main line, you must ensure the drone never drifts more than 30 meters away from the structure, even if the main line sags.

Requirement as structured

JCAB states that when tethering a drone using a main line or guide rail, the drone must not be allowed to move 30 meters or more away from the structure, regardless of the connecting line's length, such as due to slack in the main line.

Original regulatory text

なお、連結索の長さによらず、主索をたわませる等により無人航空機が物件から 30m 以上離れることがあってはならない。
