This paper describes a conflict resolution algorithm that can provide automated separation assurance for the next generation air traffic control system. The algorithm generates resolution trajectories that can be sent to the aircraft from a ground-based system via data link. With suitable reconfiguration the algorithm can also be installed on board aircraft to support airborne separation assura...

The Small Aircraft Transportation System (SATS) is a NASA project aimed at increasing access to small non-towered non-radar airports in the US. SATS is a radical new approach to air trafficmanagement where pilots flying instrument flight rules are responsible for separation without air traffic control services. In this paper, the SATS project serves as a case study of an operational air traffic...

A human-in-the-loop simulation was conducted that examined separation assurance concepts in varying levels of traffic density with mixtures of aircraft equipage and automation. This paper’s analysis focuses on one of the experimental conditions in which traffic levels were approximately fifty percent higher than today, and approximately fifty percent of the traffic within the test area were equ...

Due to the large increase in the density of aircraft arrivals at airports in recent years, it has become important to optimize the scheduling of aircraft landings in order to reduce wait time, improve airport efficiency, and minimize fuel consumption while maintaining safety. As the density of aircraft arrivals increases, however, so too does the complexity of trajectory planning and generation...

This study compared situation awareness across three flight deck decision aiding modes. Pilots resolved air traffic conflicts using a click and drag software tool. In the automated aiding condition, pilots executed all resolutions generated by the automation. In the interactive condition, automation suggested a maneuver, but pilots had the choice of accepting or modifying the provided resolutio...

Ensuring vertical separation is a key means of maintaining safe between aircraft in congested airspace. Aircraft trajectories are modelled the presence significant epistemic uncertainty, leading to discrepancies observed and predictions deterministic models, hampering task planning ensure separation. In this paper probabilistic model presented, for purpose emulating climb bounding uncertainty p...

This paper focuses on a novel morphing aircraft capability called perching: the ability of an aircraft to make a planted landing using primarily aerodynamic forces in lieu of high thrust. Specifically, the modeling of the perching aircraft’s aerodynamics and the problem of computing and optimizing a perching trajectory using this model are presented. The aerodynamic model discussed herein is de...
