Abstract
The air traffic control system was designed in the 1950s and has changed little since that time except to increase in size along with the increase in air travel. The system has been strained at times and represents a very stressful work environment for air traffic controllers. The system is viewed as still safe, but at the same time, demands have been made that the system be modernized as the size of air traffic continues to increase.

Abstract
This paper describes the task of air traffic controllers, which is to ensure safety for commercial and private aircraft, and various issues they encounter in their work. First, the paper discusses how the air traffic control system is run by the FAA (Federal Aviation Administration) and the ATCSCC (Air Traffic Control System Command Center) which is the at the head of all traffic control management. Then, the paper examines situations and conditions which can make the work stressful and difficult. Next, the paper considers staffing and management of air traffic controllers. Other issues that are explored include aircraft separation criteria and other safety measures. Finally, the paper addressed costs in air traffic control and the possibility of privatization. The paper concludes by discussing radar systems of communication and their importance.

From the Paper
"The air traffic control system is run by the FAA (Federal Aviation Administration, which uses the airspace divisions to guide the system. The ATCSCC (Air Traffic Control System Command Center is the at the head of all traffic control management. Problems such as bad weather, traffic overloads, and faulty runways are also under the jurisdiction of the ATCSCC. There is one Air Rout Traffic Control Center (ARTCC) for each center. The function of this entity is to handle air traffic within each sector except for TRACON and local airspace. The Air Each airport has an Air Traffic Control Tower (ATCT), which handles takeoff, landing, and ground traffic. The Flight Service Station (FSS) focuses its service and information on small airports and rural areas, where private pilots are in need of information such as the weather, route, terrain, and flight plan. The FSS also handles emergencies and search-and-rescue missions for aircraft that are missing or overdue."

Abstract
In this article, the writer studies literature on the subject of cooperation and coordination in communications between pilots and air traffic control. The writer discusses that the successful negotiation of emergency situations demands a full-
spectrum application of technical competence, experience, as well as the all-important efficiency of communications with air traffic control. The literature evaluated in the paper encompasses the most important issues arising in contemporary civilian aviation in connection with emergency communications between pilots and air traffic controllers. The writer notes that the literature also details the need for mutual coordination between pilots and controllers with respect to potentially ambiguous descriptions in applicable federal regulation delineating their respective emergency-avoidance responsibilities.

From the Paper
"Myriad factors can either adversely affect the ability of pilots to successfully negotiate emergencies; in that regard, some of the most crucial include: (1) a mutual commitment to a team approach on the part of both pilots and air traffic controllers, (2) preparedness for unanticipated circumstances, (3) the ability to process information in real time and deduce the optimal responses required by specific events, (4) bi-directional clarity of communications, (5) preplanning of emergency procedures, (6) appropriate responses to dynamic changes in flight plans and landing approaches, (7) the availability and reliability of emergency avoidance equipment, (8) the ability to avoid tunnel vision in crises including thinking "out of the box," and (9) procedural rules and federal regulation that provide appropriate and unambiguous protocols outlining the hierarchy of respective responsibilities between flight crews and air traffic control as well as between and among various segments of air traffic control."

Abstract
This paper provides a brief overview of the "free flight" system of air traffic control and compares it with the present air traffic control system. The paper also describes the limitations of the current air traffic system and then goes on to explain how the 'free flight' system promises efficiency and profitability for the airline industry.

From the Paper
"With more than 50,000 flights taking to the skies everyday the present US air traffic control system places increasing strain on the control room staff who have the responsibility of tracking, guiding and directing the pilots. Under the current system, the air traffic controllers resolve conflicts in airspace using radar signals and regulating traffic by means of adjusting the altitude and speed limit of the different flights. As James Coyne, president of the National Air Transportation Association, says, "All of the information that flows to and from a pilot today in virtually all aircraft is done on a strictly single-voice channel, back and forth, with human beings actually saying all the words live. As anyone can imagine, that is an extremely inefficient way to convey data." [Jacques Leslie] Pilots are dependent upon the instructions from the control room to avoid conflicts and disaster in airspace. Once the aircraft is cleared by the departure controller and left the TRACON (terminal radar control) airspace, it is monitored enroute by the personnel in the ARTCC (Air Route Traffic Control Center) who continue to provide the pilots with the traffic, altitude and speed instructions. [Craig C. Freudenrich Ph.D] For most airways however, the stipulated altitude, route and speed restrictions do not contribute to optimal efficiency."

Abstract
This paper explains that the entire system of air traffic management is dependent upon the accountability of pilots on board and the air traffic controllers, who are dependent upon the data displayed and acquired from their computer screens, dials, and gauges simultaneously being ratified by their insights of past experience and pre-determined operational guidelines. The author points out that, although English is acknowledged as the international language in aviation history, many pilots present problems of dialects, accents, and interpretations, which have resulted in crashes. The paper relates that efficient communication will go a long way in guaranteeing secured air travel; advanced technology is now being launched, and rules are being slackened to render the pilots and air controllers greater freedom. Includes a PowerPoint presentation.

From the Paper
"The confusion resulting in misinterpretations of the terminologies lead to visualization of different objects other than those it indicates to. The lack of proficiency in the English language is noticed both among the Air Traffic Controller and the pilots the United States. However, it is not confined only to the foreign pilots. It is also essential in case of the US pilots flying across the other nations and facing the controlling crews of other nationalities, to effectively comprehend the short, disconnected and unintelligible English communications similar to the expectations of the proficiency in English by the foreign pilots. (Guest Editorial: Barriers to Effective Communication: Implications for the Cockpit) Moreover, the fact of deficiency of the foreign pilots in the English Language and their confinement to some of the standard aviation phraseologies must be acknowledged."

"The Professional Air Traffic Controllers Organization (PATCO), a labor union representing civilian air traffic controllers employed by an agency . the Federal Aviation Administration (FAA) . of the United States (US) government, called a strike on 3 August 1981 (Office of AFCC History [OOAFCCH], 1985). In the ensuing months, PATCO's effectiveness as a collective bargaining organization was destroyed, the lives of hundreds of air traffic controllers and their families were quickly characterized by high levels of uncertainty and distress, air traffic safety in the US was temporarily compromised, military personnel were used as temporary replacements for the civilian air traffic controllers, and the quality of the industrial relations environment in the country deteriorated (...)"

Abstract
This paper discusses the fact that following the 9/11 tragedy many politicians and airline industry representatives began to search for improvements to the Airline Traffic Control system (ATC). The paper explains that these improvements were deigned to increase security and safety for all flight personnel, as well as for all passengers. The paper outlines some of the changes made to the ATC systems and examines the benefits of each new policy or procedure.

From the Paper
"One of the most significant changes to ATC has been the implementation of key technology, deployed at the headquarters of NORAD, located in Colorado Springs. This technology, known as Explorer, enables the NORAD team to monitor all commercial aircraft flying across the country at any given time. Previously, the technology had been used solely to monitor for incoming missiles, or military planes (Carr and Cone, 2002). The FAA also added a staff of air traffic controllers to the NORAD base, as well as in many busy sectors across the country, to assist local ATC operators in the event of a hijacking situation (Strohm, 2004). In an effort to ensure proper handling of airline safety issues, the FAA also separated the responsibility of those dealing with hijack situations. The TSA, or Transportation Security Administration, has been established. In the event of a hijacked flight, the TSA is responsible for all actions while the plane is in the air. When the flight lands, the FBI is responsible (Strohm, 2004)."

Abstract
This paper describes the evolution and the development of safety programs within the Air Traffic Control System in the U.S.

From the Paper
"The Air Traffic Control System
The responsibilities of air traffic control are varied and complex. In addition coordinating air traffic flow, they also provide traffic advisories and weather information. In recent years, considerable effort has been focused on upgrading the air traffic control system in the United States. The National Airspace System Plan (NASP) will replace 1960s vintage equipment with new technologies, and also streamline control operations. Moreover, the plan's automated systems will rely heavily on space for both communication and navigation. The NASP promises to set the standard for air traffic control.


Perhaps the primary challenge for air traffic control (ATC) is to keep up with the ever increasing demand on airspace. Between 1980 and 1987, the number of people travelling by air in..."

Abstract
The paper explains the need for improved traffic safety systems. The paper explains what fuzzy logic is, using the example of how it works to regulate temperatures on an air conditioner. It explains that fuzzy logic is used to measure imprecise and dynamic factors and allows for a reasonable judgement. In conclusion, writer states that fuzzy logic has improved the overall quality of life in other areas and posits that using fuzzy logic to assess traffic systems will result in traffic agencies making better overall decisions regarding traffic safety.

From the Paper
"Fuzzy Logic allows us to measure imprecise and dynamic factors and allow for a reasonable judgement. For example, an air conditioner employing Fuzzy Logic can automatically regulate the temperature. If it's too hot, it will lower the temperature. It it's too cold, then it will increase the temperature. However, it's difficult to define what is "too hot" and what is "too cold". Also, there's the factor of humidity (dampness and dryness). Fuzzy Logic can control the system by accepting these dynamic variables and generating an optimal temperature output, providing better comfort for the user. Fuzzy Logic is now widely used in consumer electronics, agriculture, and manufacturing systems."
