“CLEARWAY
Clearway is the area beyond the runway not less than 152m wide centrally located about the extended centerline of the runway and under the control of airport authorities. Clearway is expressed as a plane extending from the end of runway with up slop [sic] not exceeding 1.25% above which no object or terrain protrudes with exception of threshold lights.”
That took about 20 seconds. Maybe it would take longer to find a definition without the error. Over here we would say it’s 500 feet wide - FAR 1.1.
