This undated chart, released through The Black Vault, is a radar flight path chart prepared at the FAA's Anchorage Air Route Traffic Control Center. The surviving text is its legend. The legend defines radar return categories: beacon with merged primary, beacon with offset primary, split primary returns and split beacon returns. It lists the chart's preparers as cartographer Phil Shutt, automation specialist Manfred F. Keller and quality assurance specialist Anthony M. Wylie. The text reaches no conclusions and does not name any incident.
