FINAL DEGREE PROJECT PROJECT TITLE: Feasibility of commercial operations at Andorra - Pyrenees airport DEGREE: Aeronautical Engineering, Air Navigation speciality AUTHOR: Roger Mulet Morató DIRECTORS: Luis Delgado Muñoz and Ferran Pous Andrés DATA: September 2009 Overview 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.
