TLDR
In this paper, the role of future Next-Generation technologies such as automatic dependent surveillance-broadcast (ADS-B) in the overall collision avoidance concept and architecture is analyzed.Abstract:
As the aviation community moves toward the next generation air transportation system (NextGen), current airborne collision avoidance technology may become inadequate. The traffic alert and collision avoidance system (TCAS) was developed some time ago, and its ability to accommodate the air-to-air applications and air traffic control (ATC) procedures that are envisioned for NextGen is limited. There is a need to analyze the role of future NextGen technologies such as automatic dependent surveillance-broadcast (ADS-B) in the overall collision avoidance concept and architecture. This paper will describe a MITRE research effort addressing the following three fundamental research questions: What are the desired NextGen operations that are incompatible with current TCAS? What new enabling technologies and design principles could meet the NextGen needs? What are the key functional needs that ensure enhancements and modifications do not detract from safety-the primary function of the collision avoidance system? In this paper we will discuss the technical approach applied to the research, and identify projected TCAS limitations in meeting future air-to-air applications and ATC procedures.read more

TL;DR: The U.S. commercial space launch industry has changed considerably since the enactment of the Commercial Space Launch Amendments Act of 2004 as discussed by the authors, which prohibited FAA from regulating crew and spaceflight participant safety before 2012, a moratorium that was later extended but will now expire on September 30, 2015.

Method and device to help an aircraft to altitude change in case of reduced separations
TL;DR: In this article, a method and device to help an aircraft change altitude in case of reduced separations is described, which is embarked on board the airplane and comprises means for determining a performing time range during which the altitude change maneuver within reduced spacings being desired by the pilots is able to be performed.

Method for reducing nuisance alarms for anti-collision with obstacles on aircraft
TL;DR: In this paper, a method for filtering anti-collision alarms for aircraft, the said aircraft comprising means for calculating its speed and extrapolated positions on its trajectory, the extrapolation positions being calculated over a fixed maximum time period, called extrapolation time, and a topographical database of the terrain, the database comprising, within a given perimeter, data on the density of obstacles, comprises a calculation of a weighting coefficient for the extraporation time of the calculated extrapolated trajectories of the aircraft as a function of the density within a surface area included within the perimeter.

An Empirical Methodology for Engineering Human Systems Integration
TL;DR: In this paper, the authors present a methodology to improve the application of systems engineering technical processes for design, expressed in four methods that support early systems engineering activities: a requirements elicitation method, a function allocation method, an input device design method, and a display layout design method.

Development and operation of the Traffic Alert and Collision Avoidance System (TCAS)
T. Williamson,N.A. Spencer +1 more
TL;DR: The Traffic Alert and Collision Avoidance System (TCAS) as discussed by the authors is a transponder-based collision avoidance system that provides immediate protection against the vast population of aircraft already equipped with either the current Air Traffic Control Radar Beacon System (ATCRBS) transponders or the new Mode S transpuder.

TL;DR: None of the studies could refute the feasibility of airbome separation using such a concept in the cmise phase, even under extremely dense and constrained traffic situations.

Performance metric alerting: a new design approach for complex alerting problems
Liang Yang,James K. Kuchar +1 more
TL;DR: This work proposes an alternate approach that enables the alerting system to operate online in the performance space, based directly on the computed values of metrics such as false alarm probability rather than on surrogate physical metrics.
