| Abstract: The Ground Delay Program (GDP) and the Collaborative Decision Making (CDM) concepts have been studied in this project. A statistical analysis on all GDPs that occurred during 2006 in the United States of America has been done. Some statistics have been derived on the number of GDPs, their causes, the assigned delay and the number of affected flights per airport. Results show that the 90% of the GDPs took place in only 16 airports, being Newark (EWR), in New York, the airport with more regulations. In addition, the 74% of the GDPs were caused by bad weather conditions and the 90% of the total delay was assigned only in 10 airports, being Chicago the airport with more delay assigned. A same behaviour was observed with the number of affected flights: the 90% of the flights had as a destination only 10 different airports and Chicago again, was the airport with more affected flights. A clear relationship exists between the number of affected flights and the assigned delay. However, many airports with more flights and delay are also in the highest positions of the number of GDPs per airport list. Using the K-means algorithm GDPs have been classified into clusters with similar characteristics. Cluster centroids for Newark (EWR) have been used to simulate a cruise speed reduction strategy aiming to absorb part of the assigned GDP delay airborne, by flying slower but consuming the same amount of fuel than in the nominal flight. In case the GDP is cancelled, aircraft flying at reduced speed can fly recover some delay, by speeding to the nominal speed, but without incurring with extra fuel consumption. The data from the Enhanced Traffic Management System (ETMS) has been used in order to simulate the traffic with destination EWR in two 2006 days. All aircrafts types has been classified into Airbus types and their performances have been computed using the Airbus PEP Suite. Finally, the traffic has been simulated using the Future ATM Concepts Evaluation Tool (FACET). The simulation results showed that the speed reduction effects depend on the cancellation time and the number of flights flying at that time. Results show that between 4% to 5% of the total delay can be absorbed in the air. Simulating the Newark GDPs, using the centroids data and cancelling them at their average cancellation time, a 7% of delay can be recovered in the cluster 1 using the speed reduction strategy, 33% in the cluster 2 and 31% in the cluster 3 at no extra fuel consumption. |

Keywords: CFMU, agent base programming, simulation, RAMS |
| Abstract: Due to the large volume of traffic existing in Europe , the slot allocation has became a basic tool for the air flow management in an efficient way. In broad terms we could say that the slot allocation is the process responsible for management or optimize the demand/capacity balance, but keeping safety as a priority. The responsible for the allocation system is the Computer Assisted Slot Allocation (CASA). It's an automatic and centralizated algorithm and it’s included inside CFMU (Central Flow Management Unit), the Eurocontrol organization’s responsible for the management of the air traffic flow de in Europe. However, the whole slot or delays allocation process is a measure aims to priorize the safety, and it’s clear that an inefficient allocation can be very harmful, for the air operators in a special way, because it can produce serious financial losses. Therefore due to the importance of this process we want implement this useful tool. Also the fact of making it compatible with Eurocontrol RAMS Simulator, allowed us observe and analyze accurately, the result of slot allocation in very fidelity stages. |

Advisor(s): Delgado, L.
(in Spanish).
Keywords: Dijkstra, airways, route computation, optimization |
| Abstract: In this project has been developed an application which allows to know the shortest route between two points of the European airspace, if it exists. The application also computes the distance which has travel the airplane and the time of the flight, for this we must enter different parameters before as mach and flight level of cruising. At the time fpr choosing the departure and arrival points, there are two options, fly between airports or fly between waypoints or navaids, we must choose the second option, because the program doesn’t allows to calculate the route between two airports because although they were loaded, they aren’t connected with other points of the graph as the database from which information has been extracted did not contain these connections. The information necessary for create the graph has been extracted of a SkyView database. SkyView is a program which contains all information of waypoints, navaids, airways, boundaries, etc. of the European airspace. Also this program has been used for make checks of the results at the time of calculate the different routes with the application and so to ensure that works correctly. The application has been programmed with Eclipse in the Linux operating system, so it only works in this operating system. The programming language which has been used is c++ and sql for read the database, and finally the graphic design has been realized with qtDesigner. At the time of program the application hasn’t been developed without control, but has been developed a series of documents, which can find in the appendices, which has been facilitate its creation. Firstly it was developed a document with use software cases, where specifies the program stakeholders and which will be the different features. From this document has been developed a document of requirements software specification, where are detailed the different functional and nonfunctional requirements of the application. For the design phase has been developed a document of software architecture where was found class diagrams and sequence diagrams of the application. Finally, have been developed validation tests, for once the application check that it met the initial requirements. The report has been written in LATEX. |

Keywords: Optimization, global, algorithm, genetic |
| Abstract: The main goal of this TFC is to introduce the reader into the world of global optimization methods with Genetic Algorithms. In order to achieve this goal, we will begin by explaining the theoretical basis they are based upon, next we will try to corroborate them empirically by means of some simple tests. Taking into account the obtained results and all we have learnt we will try to solve a more complex and real problem. Specifically, we will try to equilibrate the load of the decks of an airplane. Due to the complexity of our problem we will find some trouble, common in those cases, like beginning with an idea and having to change it and model it until we achieve a system able to solve the problem. |

Keywords: capacity, airport, assessment, simulation, theoric, data, RAMS |
| Abstract: The study of the capacity of an airport has been -and will keep being- one of the most common and necessary activities to do when designing an airport. An efficient airport means a good performance, and therefore good incomes. To design the air-side of an airport, we must find the proper configurations according to the estimation of traffic that we aim to obtain. We also need to look further at the future, and not only prediccting how will it change in the following years of its opening. What will happen in 10 years? Will it need an extension? Will we have enough space to satisfy the demand? This is intended to stress the importance of forecasts and analysis that are done for the capacity of an airport. This TFC studies the capacity of the airport of Barcelona form a teorical, simulation and data analysis point of view. |

Set up of Eurocontrol air traffic simulator fo ATC simulations.
Final Degree Project:
Castelldefels School of Telecommunication and Aerospace Engineering (EETAC),
Castelldefels, Catalonia (Spain).
Advisor(s): Delgado, L.
Keywords: air traffic simulator, air traffic control, ATC, simulation, eDEP |
| Abstract: In this Project, the set-up of an air traffic control simulator has been carried out. eDEP simulator, provided by Eurocontrol, has been the one used. As a part of the Project, the platform preparation for its execution in a local area network has been done. Also some adaptations needed for a practice environment. It’s intended to use the eDEP platform for the practical part of some of the subjects of the Aeronautical Degree. Using Eclipse development environment, Java code corresponding to eDEP classes have been prepared and compiled. By using Eclipse, also some configuration files needed to execute eDEP on a network had been created and executable files have been generated to launch simulation. Also airspace and traffic files for three different simulations had been prepared. Two of them are air traffic control on the cruise phase and the third one will simulate approach control. One of the simulations for cruise control is using FIR/UIR Barcelona airspace data. For this simulation, the airspace file (containing position of navigation aids, airways and sectorization) and the traffic file that will be used in the practice have been created. Limitations of eDEP as air traffic simulation platform have been evaluated and it has come to the conclusión that could be interesting the development of some additional code to simulate a flight strip system. An additional limitation detected is the non-availability of voice communications between controller positions and pilot positions. For the flight strip system an study of software engineering has been carried out. Regarding the lack of voice communications, an VoIP software running over a LAN has been used. During the Project, an important effort about documentation has been performed. Has been documented from the compilation and execution with Eclipse to the configuration of airspace and traffic files. A basic user manual has been prepared for the controller positions and for the pilot positions. |

Feasibility Study of Commercial Operations at Andorra-Pirineus Airport.
Final Degree Project:
Castelldefels School of Telecommunication and Aerospace Engineering (EETAC),
Castelldefels, Catalonia (Spain).
Advisor(s): Delgado, L. & Pous, F.
Keywords: airport operations, commercial operations, limitations of use |
| Abstract: The project pretends to perform a technical and commercial study about the Andorra - Pyrenees airport. The target is to study the feasibility of the operations at the airport in its current status and whether it is possible to improve it. The study analyzes two kinds of air traffic which the airport is capable to attract, the international and the regional traffic. Studying the demand, has been determined that exists a potential market of foreign visitors, who use other airports for their travels and that the Andorra – Pyrenees airport can capture this passenger traffic. For studying the feasibility of the operations, two target cases have been defined, which are the most representatives, as well as the minimum number of passengers to transport in each operation, and also two aircrafts which permit to cover the kinds of traffic studied. The current situation of the facilities has been studied and then, the feasibility of the flights between La Seu d’Urgell and the target destinations and vice versa. It has been calculated along the year with the different meteorological conditions and both aircraft design. The study of the feasibility of the flights has been performed from the point of view of an airline operator. The results show that in the current conditions, it is not possible to achieve the objectives set, and therefore the target operations are not feasible. With the aircrafts design and the target routes, currently, the airport is not feasible. For achieving the objectives set, it has been studied whether introducing improvements in the runway length and defining a new contingency procedure it is possible to reach the objectives. The results show that there are significant changes in the final results, which permit to reach the expected objectives, making the target operations feasible. |
