Airspace Constraints And Controller Workload On ATS Routes

Improved Essays
1. INTRODUCTION
Airspace constraints and controller workload are foremost among the factors limiting the airspace capacity. Controller workload is the physical and mental work that the controllers are supposed to undertake so that air traffic can be managed safely [1].
Airspace can be divided into subdivisions to provide more efficient air traffic services and to reduce the effect of the controller workload on Air Traffic Management capacity. This process is called the sectorization [2].
ATS route is a special way designed to ensure that traffic flows are in accordance with air traffic services rules [3]. There could be many intersecting and parallel routes in a sector. The network structure of ATS routes in the airspace may prevent from dividing the airspace into subdivisions. Therefore, ATS routes may need to be rearranged.
Unidirectional routes at the same level (odd and even) can be grouped at two different points so that two different sectors can be established. This method is called "Roundabout" by the European Organization for the Safety of Air

However, as air traffic increases, the controller workload becomes the primary determinant of airspace capacity. Therefore, factors affecting workload such as number of aircraft per hour, average flight time per sector, number of potential conflicts, number and quality of coordination units, number of level changes are taken into account to calculate airspace capacity. Real-time and fast-time simulations are often used in controller workload-based methods. Fast-time simulations are insufficient for taking into account human factors such as controller reasoning and thinking. This is why real-time simulations are often used after fast-time simulations. For example, in Japan, after TAAM and SIMMOD fast time simulations are used to calculate sector capacity, the controller workload is evaluated in real-time simulations

    In 1956, there was a mid-air collision in Grand Canyon. A Douglas DC-7 (United Airlines) collide with a Lockheed L-1049 Super Constellation (Trans World Airlines) resulting in killing every single person in those two airplanes, which were 128 people total. When the Civil Aeronautics Board investigated this tragedy, they found out that ground controller in the Salt Lake City knew about that those two airplanes were on a crash course. However, since those two airplanes were in the uncontrolled area, the Salt Lake City ground controller wasn’t obligated to tell either of those pilots.…

    El Dorado International Airport Airside Analysis El Dorado International airport was built in 1953 and since then, the airport has been renovated to adapt to the fast rhythm of aviation. The following paper will summarized important information regarding the airport 's airside and an analysis will be done to see if the current procedures and airport configuration is meeting the current and future needs as well as the capacity levels to operate in an efficient way. El Dorado Airport Airside Runways Originally, El Dorado International Airport was planned with one runway. In 1995, the airport was at its full capacity so the government decided it was time to build a second runway. Currently, El Dorado has two runways: 13L/31R and 13R/31L. Runway…
