The ICAO standard I think was upgraded in 2006. It was recommended at that time that an additional 90 metres be added, actually, not 60. You've recommended 60. That is my understanding. The United States currently is at 300 metres, approximately, or 1,000 feet, so it is 330 metres, probably, or somewhere around there.
