Imagine that you are an air traffic controller on a busy evening, responsible for directing 100 planes per hour heading to a major metropolitan area. (see fig. 1.) your job is to keep all these planes safely separated and on time to their destinations. To do this, you must quickly and accurately solve a multitude of distancerate- time problems. This air traffic control scenario provides an exciting, challenging, and meaningful context for prealgebra and elementary algebra students to “model and solve contextualized problems using various representations” (nCTm 2000, p. 222) that address diverse learning styles and preferences as well as different levels of mathematics preparedness.

While previous research has addressed air traffic controller workload as a function of cognitive complexity due to environmental and to a lesser degree, organizational factors, significantly less attention has been paid to the role of displays and complexity in the ATC environment. One drawback to new display technology is that in dynamic human supervisory control domains, it is not always clear whether a decision support interface actually alleviates or contributes to the problem of complexity. In an attempt to quantify the influence of environmental and display complexity factors on cognitive complexity, an experiment was conducted to determine if these two components could be effectively measured. Results revealed that the environmental factor of increasing aircraft number affected subject performance only slightly more than the display complexity factor of increased color categories. These findings are important because the use of color in displays is meant to reduce environmental complexity, not add to it.

Visual simulation is the most important manifestation of virtual reality technology. Take a civil aviation airport as an example of visual simulation, based on the real-time, interactivity and realism of visual simulation system, we discuss Creator 3.0 in building three-dimensional scene of the civilian airport, and the development of visual simulation system based on Vega Prime. The simulation results show that it provides the basis for the safe and reliable in air traffic control, reducing the working pressure of the air traffic controller, improving the operating efficiency of the air traffic, and increasing the traffic flow of air and surface.

Training a developmental (air traffic controller in training) to certification is a lengthy and expensive process. To limit losses due to poor performance in training, the FAA has implemented a policy to reassign some developmentals to less complex air traffic control (ATC) facilities following voluntary or involuntary removal from training at more complex facilities. The National Employee Service Team (NEST) is implementing the policy. We reviewed the NEST processes and assessed effectiveness based on the extent to which the NEST recommendations are accepted and the likelihood that developmentals reassigned in accordance with NEST recommendations succeed in training at the new facility. We found that NEST recommendations to retain or terminate developmentals and type and level facility for reassignment are accepted by the FAA at a high level. Furthermore, the success rate of developmentals at a new facility is greater than 90%.

The air traffic controller provides a service and can do so effectively only with the cooperation of his customers, namely the pilots of many different types of aircraft. For the purpose of this paper it is assumed that pilots do not wittingly take avoidable risks and are fully capable of finding their way from one place to another by the shortest available route. According to I.C.A.O., A.T.C. exists to provide ‘safety and expedition’, but, left to his own devices, the pilot can take care of his own ‘expedition’ so that the main function of A.T.C. is to provide a safety service. When A.T.C. has to regulate flights for safety reasons, however, it may have to ask a pilot to deviate from his chosen flight path. It then has to assume a measure of responsibility for expedition, but safety is still the prime consideration.

Under Federal Aviation Administration (FAA) sponsorship, MITRE's Human Performance Assessment Group is contributing to the design of an expert system to support air traffic control. We are working closely with a team of expert, full-performance-level air traffic controllers to capture the formal and informal rules they use in maintaining flight safety and efficiency. This paper documents our approach to working with these experts, the results of using that approach, and a distillation of lessons learned.

This paper describes the basic principles of a method developed to guide aircraft accurately down to the runway in a time-of-arrival constrained environment. The method is designed to be used in a ‘zone of convergence’ context or in any similar advanced air traffic control system characterized by the integration of control phases over an extended area on the one hand and true ‘computer assistance’ to the air traffic controller on the other; that is, assistance provided at the decision-making level through the automatic generation of guidance advisories.The method includes two closely-coupled basic components; namely, a ‘predictor’, which computes a trajectory once initial conditions and plans are known, and a ‘profile manager’, which adapts the plans to meet the time constraints and generates the guidance directives on the basis of present position, actual surveillance information, aircraft operation and route constraints.

Developing an interactive teaching medium is one of the solutions to deal with student diverse learning styles. This study attempted to develop an interactive medium to teach english vocabulary to young learners in the form of CD. Borg and Gall’s (1989) model of research and development which consisted of nine stages was employed. Needs analysis, planning, product development, product validation, main product revision, main field testing, operational product revision, operational field testing, and final product revision were performed. The data were gathered using interview and questionnaires. Both qualitative and quantitative data analyses were run. The result of prototype tryout to 40 fifth-grade students suggested no significant revision. Thus, the product could be tried out, at a larger scale, to 200 fifth-grade students who were selected randomly to represent ten elementary schools in Banyuwangi. Due to students different levels of proficiency, various problems appeared during the product implementation. Yet, findings of the study in general have confirmed the effectiveness of an interactive medium in improving student motivation to study English vocabulary.   Keywords: Interactive medium, English vocabulary, young

This analysis of en route air traffic controller communication was part of a larger Federal Aviation Administration effort to redesign the training program for en route air traffic control. This presentation concentrates on the analysis and results of the team communications as they relate to Controller Resource Management (CRM). The team controller communication takes place between the radar controller and the radar associate controller as they perform their related tasks in the management of the sector air traffic. This study used an inductive approach to look at communication frequencies across different types of controller teams. The controller teams were manipulated by using different combinations of expert, intermediate, and novice controllers, and these teams were compared under moderate and heavier workloads while managing simulated air traffic. The team communications were coded and analyzed at the speech turn level. Observations, situational inquiry, and answers supplying information combined to make up over half of the speech turns used by the controllers in team communication. A more detailed analysis by controller position and performance identified communication frequencies for the better performing sessions. These results are interpreted in relation to a recent mental model of the en route air traffic controller and are further explained based on results of a study of live traffic team communication. The discussion explores the roles of the team members in maintaining effective CRM.

The objective of this study was to examine the potential benefits for air traffic controllers from the use of automated weather advisories. In a part-task simulation, we used a weather support tool called Automatic Identification of Risky Weather Objects in Line of Flight (AIRWOLF) that (a) detects conflicts between aircraft and hazardous weather, (b) alerts the controller, and (c) generates automatic weather advisories. During the simulation, air traffic control (ATC) subject matter experts responded to AIRWOLF alerts and either provided weather advisories to pilots via radio in two main conditions or provided data link communication in a third control condition. Automated advisories (a) eliminate the need for a manual production of weather advisories; (b) reduce the production time, voice duration, and overall advisory duration; and (c) reduce the cognitive workload associated with the dissemination of weather advisories. The results showed that the AIRWOLF tool could support air traffic controller weather avoidance actions and provide accurate and timely weather advisories to pilots. The weather advisory tool could support en route controllers for the safe, efficient, and strategic efforts required to handle adverse weather conditions in the en route environment.

The formation or mangement transition of Air Traffic Control or Air Traffic Services (ATC/ ATS) policy in reference to the Law Number 1 of Year 2009 on Aviation, in article 271 paragraph (1) and (2) and (4), international regulation of ICAO Document 9 191 / 3 Manual on Air Navigation Services Economy as well as other related regulations and policies in participating the increase of aviation safety and service quality, Air Traffic Services performance and Airport Service in entire national air space. In order to make transition formation of Air Traffic Control/Air Traffic Services management to the goverment, it is necessary to do steps to review some aspects as follow : legal/regilation aspect, institutional/organization al aspect and operational/service aspect. Management of Air Traffic Control/Air Traffic Services (ATC/ATS) has to be caharacterized as public services, reducing bureaucracy, integrated service, non-profit oriented and financially independent and organizationally effective and efficient in atool to create unity and entity as well as state's security. The unitary Stafe of Republic of Indonesia has be run by the goverment nationally in a single container.
