In the U.S., the recommended RSA may extend to 500 feet in width, and 1,000 feet beyond each runway end (according to U.S. Federal Aviation Administration recommendations; 1000 feet is equivalent to the international ICAO-RESA of 240m plus 60m strip).
I USA kan den rekommenderade RSA (runway safety area) vara uppemot 500 fot brett och 1000 fot bortom varje rullbanas slut (enligt USA Federal Aviation Administration rekommendationer motsvarar 1000 fot den internationella standarden ICAO-RESA på 240 meter plus en 60 meter remsa).
