Separating airplanes is numero uno among an air traffic controller’s many duties, but it’s really only the tip of the iceberg. On a day-to-day basis, we’re purveyors of information, passing it back and forth between parties who can make use of it.
Weather and NOTAMs are a huge percentage of the mountains of data controllers process daily, and a significant chunk of that comes from pilot reports. Some pilots wonder how the information they share gets processed by ATC. As one IFR reader expressed: “It appears that most reports of icing/tops/bases that are reported to ATC never make it into the PIREP system.”
