31-674: The Horticulture Building was a building at the Dakota County Fairgrounds in Farmington, Minnesota , United States. It was built in 1918 and demolished in 1988. The Dakota County Fair began in 1858 when the Dakota County Agricultural Society was organized. Henry H. Sibley , the first governor of the state of Minnesota , was guest speaker at the first fair which was held in Nininger . The fair moved to Hastings ,
62-487: A different ICAO code. Pilots typically use high frequency radio instead of very high frequency radio to communicate with a center when flying over the ocean, because of HF's relatively greater propagation over long distances. Military aircraft, however, are typically equipped with ARC-231 SATCOMs that allow over-the-horizon communication. Area control centers (ACCs) control IFR air traffic in their flight information region (FIR). The current list of FIRs and ACCs
93-450: A first-come, first-served basis. Aircraft passing from one sector to another are handed off and requested to change frequencies to contact the next sector controller. Sector boundaries are specified by an aeronautical chart . Air traffic controllers working within a center communicate via radio with pilots of instrument flight rules ( IFR ) aircraft passing through the center's airspace. A center's communication frequencies (typically in

Most centers are operated by the national governments of the countries in which they are located. The general operations of centers worldwide, and

Some centers have ICAO-designated responsibility for airspace located over an ocean such as ZNY and ZOA, the majority of which is international airspace .

Farmington is home to three properties listed on
465-903: The United States, centers are electronically linked through the National Airspace System , which allows nationwide coordination of traffic flow to manage congestion. Centers in the United States also have electronic access to nationwide radar data. Controllers use radar to monitor the progress of flights and instruct aircraft to perform course adjustments as needed to maintain separation from other aircraft. Aircraft with center contact can be readily distinguished by their transponders . Pilots may request altitude adjustments or course changes for reasons including avoidance of turbulence or adverse weather conditions. Controllers can assign routing relative to location fixes derived from latitude and longitude , or from radionavigation beacons such as VORs . Typically, centers have advance notice of
