This paper discusses a novel approach to associate and re ne aircraft track data from multiple radar sites. The approach provides enhanced aircraft track accuracy and time synchronization that is compatible with modern air tra c management analysis and simulation tools. Unlike existing approaches where the number of aircraft in the radar data must be assumed, this approach requires no such prio...

The problem of deciding how to land aircraft approaching an airport involves assigning each aircraft to an appropriate runway, computing a landing sequence for each runway and scheduling the landing time for each aircraft. Runway allocation, sequencing and scheduling for each aircraft must ensure the scheduled landing time lies within a predefined time window and meet separation time requiremen...

Abstract High performance aircraft of the future will be designed lighter, more maneuverable, and operate over an ever expanding flight envelope. One of the largest differences from the flight control perspective between current and future advanced aircraft is elasticity. Over the last decade, dynamic inversion methodology has gained considerable popularity in application to highly maneuverable...

This paper focuses on the aircraft landing problem that is to assign landing times to aircraft approaching the airport under consideration. Each aircraft’s landing time must be in a time interval encompassing a target landing time. If the actual landing time deviates from the target landing time additional costs occur which depend on the amount of earliness and lateness, respectively. The objec...

This study examines the 20-year impacts of emissions from all commercial aircraft flights worldwide on climate, cloudiness, and atmospheric composition. Aircraft emissions from each individual flight worldwide were modeled to evolve from the subgrid to grid scale with the global model described and evaluated in Part I of this study. Simulations with and without aircraft emissions were run for 2...

Situational awareness and decision-making are necessary to identify and select the optimal set of mutually non-exclusive hypothesis in order to maximize mission success by adapting system behavior accordingly. This paper presents a hierarchical and decentralized approach for integrated damage assessment and trajectory re-planning in aircraft with uncertainties in navigational decision-making. A...

Regulatory agencies worldwide are working towards safely integrating unmanned aircraft into their respective national airspaces. Reliability assessment of unmanned aircraft is a key step in the certification process. This thesis presents an analysis framework for the reliability assessment of small unmanned aircraft. Specifically, the effect of the placement of actuators and control surfaces on...

Aircraft conflict avoidance is a critical issue in Air Traffic Management, which can be addressed, among others, by means of Mixed Integer Non-Linear Programming (MINLP) techniques. In this work we introduce a new approach to address, via velocity regulation, the problem of avoiding conflict for a set of aircraft flying in an air sector at cruise flight. Speed variations for all aircraft are to...

Experts from various aircraft sub-domains have to collaborate in order to design an aircraft system. Each sub-domain thereby focuses on a particular aspect of the system and uses special software tools to model those aspects and run various calculations. As those models partially overlap, inconsistencies can occur that might lead to delays in the design process or malfunctions of the aircraft s...
