In 1992, the FAA entered into a cooperative research agreement with the Air Transport Association of America to determine the value of providing Traffic Situation Display data to the aviation industry. The research found that providing such information would offer economic benefits to airlines by allowing increased dispatching flexibility and more efficient management of aircraft and crews. As a result of this finding, in December of 1997, the FAA created the Aircraft Situation Display to Industry (“ASDI”) data feed. The ASDI feed uses Traffic Situation Display information, but filters out aircraft being used for military and other sensitive government operations. In order to subscribe to the FAA’s ASDI data feed, a company must enter into a Memorandum of Agreement with the FAA. The Memorandum of Agreement sets forth the conditions and limitations by which a direct subscriber can make the ASDI feed available to users and by which the direct subscriber can market the data to secondary subscribers. Subscribers can obtain one of two types of ASDI data streams: (1) a near real-time display; or (2) an historical display that is delayed by at least five minutes. The Aviation Association decided that it wanted the option of blocking certain aircraft from the ASDI feed. Blocking the information at its origin — the FAA’s hub site — would preclude any possibility of information about the location of those blocked aircraft from ever reaching an ASDI primary or secondary subscriber. Accordingly, the Aviation Association asked the FAA if it could provide to the FAA a list of aircraft registration numbers to be filtered out of the ASDI feed; the FAA agreed. The Aviation Association now provides such a list, called the Block List, to the FAA on a monthly basis. The Block List contains only aircraft registration numbers. The FAA enters the numbers from the Block List into its system, and program software filters out those aircraft from the ASDI data feed. The FAA does not solicit Block Lists.
