Bounding Information

Bounding information is used to limit the output to a specific geographical area.You don't absolutely have to specify bounding information. If you don't, the output file will contain all of the currently active Temporary Flight Restriction (TFRs).

Instead of the rectangular latitude/longitude coordinate method employed in most programs, this site uses circular bounding. You specify the three or four letter FAA/IATA identier of an airport at the center of your area of interest and a fixed radius (in nautical miles) from the center airport. The output file will contain all TFRs within the bounding radious.
