“…Thus, a collaborative decision-making process might involve multiple pilots and air traffic controllers. It is currently an open question as to how a distributed decision-making process can be structured so as to achieve an optimal outcome for the group of airspace users as a whole (e.g., see Dwyer & Landry, 2009;Metzger & Parasuraman, 2005;Wickens & Colcombe, 2007). One option is that the ATM service provider can act as an independent arbiter in situations where agreement cannot be reached, or where the number of affected parties makes collaborative decision making infeasible.…”

Current Air Traffic Management research programs (i.e. Single European Sky ATM (air traffic management) Research (SESAR), next generation air transportation system (NextGen)), try to overcome airside capacity shortages while improving cost-efficient operations and safety. An increment in the airspace traffic density can lead to congested traffic scenarios for which it becomes necessary to develop new safety procedures that address multithread threats. This paper considers some of the difficulties in establishing validation of the airborne collision avoidance system (ACAS), which constitutes the last-resort for reducing the risk of near mid-air collision between aircraft in a multithread scenario. A causal model that is specified in Colored Petri Net (CPN) formalism is presented as a key approach to analyze the state space of a congested traffic scenario in which the events that could transform a conflict into a collision are identified, providing a challenging tool not only for validation but also for the implementation of a new ACAS logic. The InCAS EuroControl simulator has been used to illustrate the importance of cause-effect analysis for the relationships between various encounters that arise in a multithread scenario, in which TCAS II v. 7.1 fails to avoid a collision when two Resolution Advisories are issued without consideration of the downstream effects.

“…With steady increase in air traffic, current air traffic control (ATC) may not handle proper separation assurance [1]. Traffic alert and collision avoidance system (TCAS) work well as a tactical safety backups to avoid collision, but cannot perform separation assurance [2]. Future ATM concept envisages delegation of separation assurance responsibility to flight crew either completely or partially with help of an on-board advisory system which would maintain standard separation which will be called as separation assurance (SA) system [3].…”

Aircraft need to be separated from other aircraft by either a minimum vertical distance of 1000ft or by a minimum horizontal distance of 5NM to avoid mid-air collisions. Traffic Alert and Collision Avoidance System (TCAS) work well as a tactical safety backups to avoid collision, but cannot perform separation assurance. This paper presents the design aspects of system that would predict separation infringement and provide flight crew with necessary guidance for maintaining separation. This paper discusses formulation of system function based on ADS-B, mathematical models, simulation and results. A system model has been implemented in MATLAB and various encounters with different speed ratios at various conflict angles has been fed as input to system model with a goal of avoidance and recovery to original waypoint. Both Heading and Speed maneuvers are evaluated and results are presented. The required strength of resolution maneuver as a function of conflict geometry is studied and automatic maneuver selection function is implemented in system model and maneuver selection function is evaluated with discussion of results.
