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.

A Thermal-Solar System for De-Orbiting of Space Debris
This paper presents a system for removal of space debris, which can be placed on geocentric, heliocentric or Sun-synchronous orbit. The system is composed of two parabolic mirrors, a large one and a small one. The concav...
IAR-93 military aircraft monument
In this presentation, we will concentrate on the vertical support, which is free from all sides. A Finite Element Model (FEM) of the IAR-93 aircraft monument has been developed in PATRAN/NASTRAN®, partly from a previous...
A Practical Method to Estimate the Aerodynamic Coefficients of a Small-Scale Paramotor
There are few aircraft other than lighter-than-air vehicles that have the payload carrying capability, short field take-off, and slow speed ranges afforded by a powered parafoil. One very interesting aspect of the powere...
