A simulation of integrated air and ground operations was conducted to demonstrate procedures, flight management automation, data link technology, and air traffic control decision support tools for improving Air Traffic Management (ATM) efficiency. Air traffic controllers managed simulated arrival traffic using Center-TRACON Automation System (CTAS) tools. Flight crews in Flight Management Syste...

Half of all reported near mid-air collisions involve at least one general aviation aircraft. More than half of NTSB reports of mid-air collisions occur in the vicinity or in the traffic pattern of an airport, and a majority of them occur at non-towered airports. This paper proposes a concept for traffic collision prevention targeted for general aviation aircraft operating in the vicinity of non...

The proposed next-generation air traffic control system depends crucially on a surveillance technology called ADS-B. By 2020, nearly all aircraft flying through U.S. airspace must carry ADS-B transponders to continuously transmit their precise real-time location and velocity to ground-based air traffic control and to other en route aircraft. Surprisingly, the ADS-B protocol has no built-in secu...

Road dust and vehicle exhaust are the main sources of air pollution in cities, especially in recent years with the quantity of vehicles and transportation construction continuously soaring; the hazy weather has been a dominant urban pollution form which is widely concerned by the Chinese society. By establishing a relationship model between traffic and land use, then applying analytic hierarchy...

This paper introduces several algorithms which build optimal configurations of Air Traffic Control sectors, taking into account traffic prediction, sector capacities and the number of available control positions.

The U.S. air transportation system is the most productive in the world, moving far more people and goods than any other. It is also the safest system in the world, thanks in part to its venerable air traffic control system. But as demand for air travel continues to grow, the air traffic control system’s aging infrastructure and labor-intensive procedures are impinging on its ability to keep pac...

This is a substantial and complex project that will need to accommodate sometimes disparate civil and defence operational requirements, provide a base system that can readily incorporate new software functions to meet Australia's future air traffic demands, and achieve operational and financial efficiencies for both organisations. Over the last five or so years, Airservices Australia and the RA...

Urban air pollution is one of the major environmental problems faced by the developing countries. Studies in large Indian cities revealed that ambient air pollution concentrations are at such levels where it can cause serious health impacts. Lucknow, a fast growing city is not an exception to this. Researchers from the city have studied various aspects of air pollution during the last one and h...

The Traffic alert and Collision Avoidance System (TCAS) was designed to prevent mid-air collisions by portraying a time-critical “resolution advisory” (RA) to the pilot. Complying with a TCAS RA is generally considered the safest course of action and takes priority over all other forms of air traffic management; however, pilot compliance with TCAS RAs is surprisingly low. One proposed solution ...
