FAA’s Free Flight Modernization Initiatives
**** Hidden Message ***** An Update on:<BR>2<BR>© 2000 The MITRE Corporation<BR>Abstract<BR>In the early 1990’s, airlines recorded record losses, most notably due to traffic delays. The Air Transport<BR>Association estimated the cost of delays alone at $3.5B per year - some avoidable, some unavoidable. In<BR>August 1993, the National Committee to Ensure a Strong Airline Industry reported, “…In the history of<BR>American business, there has never been a major commercial industry whose minute-by-minute operating<BR>efficiency was capped by the daily operating efficiency of the federal government - except for the airlines.”<BR>There was a growing recognition that the ATM system in the US was not making significant progress toward<BR>taking advantage of advances in CNS and computing technology. These concerns gave birth to Free Flight.<BR>"Free Flight" is a concept that reflects an operating environment wherein airspace users are granted greater<BR>freedom in planning and operating flights in order to reduce operating costs and enhance the safety and<BR>capacity of the national airspace system (NAS). Free Flight is the core concept underlying current FAA<BR>modernization plans (NAS Architecture 4.0, FAA, January 1999).<BR>"Free Flight Phase 1" (FFP1) is an FAA implementation program to expedite the fielding of low-risk,<BR>potentially high benefit capabilities at selected locations as a first step in fulfilling the concepts of Free<BR>Flight. Begun in 1998, FFP1 will complete the implementation of five new air traffic management capabilities<BR>at over 25 sites by 2002.<BR>“Free Flight Phase 2” (FFP2) is a follow-on program to FFP1 designed to sustain the momentum of FFP1 and<BR>add additional capabilities to the National Airspace System. Some FFP1 capabilities will be geographically<BR>expanded and new capabilities will be deployed. The most notable new capability will be CPDLC.<BR>“Safe Flight 21 is an FAA Free Flight implementation program that implements advanced communication,<BR>navigation, and surveillance capabilities for safety and system capacity enhancements. The primary<BR>implementing technologies for Safe Flight 21 activities are Automatic Dependent Surveillance – Broadcast<BR>(ADS-B) and aircraft avionics called Cockpit Display of Traffic Information (CDTI).<BR>The presentation will highlight the current status of these Free Flight initiatives. 好东西哦~~~ initiative, 这个词我喜欢。
