Free Flight vs. Centralized Air Traffic Management
Journal Title: INCAS BULLETIN - Year 2011, Vol 3, Issue 4
Abstract
The current Air Traffic Management system is subject to structural changes, which are expected over the next 20 years. These changes are required for a number of reasons: The current system inflicts delays and fuel inefficiencies to flights (as demonstrated by the historic Paris-Miami Air France flight in April 2010) The current system has structural and operational capacity limitations Under current system, the complexity of the Air Traffic Controller’s work increases steeply with traffic Voice communication on a single radio frequency in ATC is limitative and subject to errors Safety is sometimes jeopardized and separation relies on a safety net (ACAS) The introduction of the ACAS systems as a separation safety net presents a structural risk in the classic ATC philosophy (as demonstrated by the Überlingen 2002 mid-air collision) ATM is the only system left in Civil Aviation, with virtually no automated core process There is a major choice to make for the future Air Traffic Management automation in both NextGen and SESAR programs: the free flight concept, and the opposite, the centralized management. This paper is an assessment of both scenarios, and their implications for traffic capacity, air traffic control complexity, safety and efficiency.
