Yes he was. There are actually two maps, depending on whether the

There are four maps per station. A short range(0-3 miles) and long
range (0-x). X depends on your terrain. When I worked at GFK the
horizon was at 10 miles so that's as far as the chart went. Here at BIL
the farthest mountains are 100 miles away so thats how far the chart
goes out. There are two charts for daytime and two charts for nighttime
