We have taken an off-the-shelf, commercial continuous speech recogniser and conducted evaluations for the domain of Air Traffic Control. The language of this domain proved to be quite unrestricted, contrary to our initial intuitions. Our experiments show that constraints typically used by speech recognisers do not provide accurate enough results and need to be augmented with other knowledge sou...

Eulerian models are used to represent the air traffic environment as traffic flows between interconnected control volumes representing the airspace system. While these models can be manually derived for simple air traffic patterns, computer-based approaches are essential for modeling realistic airspaces involving multiple traffic streams. A computeraided methodology for deriving large-dimension...

An understanding of convective weather impacts on en route airspace capacity is a first step toward development of predictive tools to support both tactical and strategic routing decisions in storm-impacted airspace. This study presents a model for traffic reductions in en route sectors that result from convective weather impacts. A model to predict the impact of convective weather on en route ...

This work proposes a novel market-based air traffic flow control model considering competitive airlines in air traffic network. In the flow model, an agent based framework for resources (link/time pair) pricing is described. Resource agent and auctioneer for groups of resources are also introduced to simulate the flow management in Air Traffic Control (ATC). Secondly, the distributed group pric...

This study addresses the significant changes in air transportation for Turkey with opening of Istanbul Airport and investigates advantages disadvantages brought about by new airport. Previously; providing a service Istanbul, Atatürk had limited capacity terms resulting mostly ineffective use time resources. Thus; this points out how İstanbul solves problems experienced previously expectations b...

Flight simulators are becoming more sophisticated and realistic, and the requirements of those using them are becoming more demanding. Air traffic control simulation for such simulators is now approaching the real problem of air traffic control, where several aircraft need to be scheduled for safe approach and landing or for safe passage through the air space that an air traffic controller is r...

Three different stereoscopic 3D visualisations are compared with the 2D display currently used at air traffic control (ATC) controller working positions. Using safety critical air traffic scenarios, air traffic controllers (ATCOs), pilots, and two groups of laypersons, one of which with an appropriate training, are asked to judge safety critical scenarios showing two converging aircraft. To sim...

Dynamic sectorization is a powerful possibility to balance the controller workload with respect traffic flows changing over time. A multi-objective optimization system analyzes flow time and determines suitable time-dependent sectorizations. Our dynamic integrated into radar display as part of working environment for air controllers. use case defining climate-sensitive areas leads changes in fl...
