- Air Budjet: a VTOL virtual operator company in PortugalPublication . Duarte, Manuel Mendes; Baltazar, Maria Emilia; Silva, J.Creation of sustainable transportation service for a new and virtual airline company that uses VTOL aircraft in order to increase mobility and flexibility in Portugal. This study started with the VTOL concepts, peripherally and accessibility, and business models and plans reviews. The air service characterization was then carried out using localization and trajectory optimization algorithms, thus allowing to elaborate two applications (software): one for clients to book their flights and another that compiles flight's data booked by clients and optimizes flights routes/trajectories. With this study, it is possible to depict the viability of the economic-financial results of the new virtual company and the application development results with the optimized trajectories. The development of this air service will increase accessibility and mobility in all regions of Portugal and companies that cannot afford the costs of executive aviation, too. In order to facilitate the booking of the flights, an application was created for the client in order to optimize the company costs related to this air service, and thus to make the cost of a trip more appealing; a second application was elaborated that optimizes the trajectories of the aircraft.
- Airports Catchment Area Size Definition: a Portuguese Case StudyPublication . Baltazar, Maria Emilia; Silva, JorgeThe definition of the Catchment Area of an airport is very broad and current literature suggests doing it in combination with certain pre-defined criteria: the assessment of the impact or effectiveness of a certain airport, or from the perspective of competition between airports. This paper aims to assess the validity of the hinterland defined by the Portuguese airport manager, ANA - Aeroportos de Portugal. A case study was developed involving the three main national airports: Lisbon (LIS), Oporto (OPO) and Faro (FAO). ANA defined the hinterland of each airport. Thus, a survey was developed to the companies located within the hinterland of every airport aiming to understand the existence of any relationship between them and the closest airport. We followed a stratified sample method to determine the size of the survey. We only considered import and export companies with the highest business volumes. Data analysis was performed using GIS (Geographic Information System), that is a software, spatial data and computational procedures system that enables and facilitates the analysis, management and representation of space and phenomena that occur in it. We collected a total of 243 surveys. The main conclusion of the study was that the calculation of an airport’s hinterland based exclusively on the travel time or distance is, potentially, misleading. It is proposed the use of other factors. The validity of such a method and practice raises some doubts. The actual distribution of economic activities and population is ignored as well as the mutual influence of several airports. Further research is now needed to calculate airports actual influence.
- CDM description and operational implementation challengesPublication . Netto, Omar; Silva, Jorge; Baltazar, Maria EmiliaThe purpose of this research is to discuss a subject that, today, is a significant challenger of all the International Civil Aviation Organization (ICAO) signatory countries: the implementation of the Performance Improvement Areas preconized in the Global Air Navigation Plan (GANP). To achieve the objective of providing a better understanding of Airport Collaborative Decision Making (A-CDM) processes the strategy chosen was to present the vision and implementation of the main entities representing the aviation area, such as the didactic form as the article is sequenced and the case studies discussed will present solutions for countries that aren’t so advanced in the implementation of their A-CDM operational processes. Also, the article will act as a guide for all stakeholders. The contribution of the research will be to provide further support to all stakeholders in the air transport sector, regarding basic knowledge and more technical approaches of compliance with the recommended guidelines for the next decades in GANP. ICAO. In this specific case, regarding Performance Improvement Area: Airport Operations and the A-CDM module.
- Optimizing process of airport passengers flowPublication . Gonçalves, J.; Silva, J.; Baltazar, Maria EmiliaThe increased demand for air transportation has enlarged congestion problems in the areas of Passenger Terminals. This study proposes how to optimize the flows of passengers at the airport of Madeira to increase airport efficiency. There are two specific approaches to achieve this study objective. Firstly, we analyse the flow of passengers at the airport terminal to detect where are the most critical congestion points. Secondly, using simulation software (MassMotion) we analyse different layouts of the airport terminal, including ramp area, considering passengers flows of different typologies, to find the most efficient layout configuration. This study optimizes the flow of passengers in the terminal area of the International Airport of Madeira, making it more efficient in routing passengers and thus maintaining control over congestion levels. Thus, the proposed configurations for Check-in, Security, Border Control, Boarding Gates, Embark, Disembark, and Luggage Claim areas allow to considerably reduce (or even eliminate) passenger congestion at these critical points. An airport is a complex transport infrastructure, and therefore any change in its physical structure must be made during its period of operation. Structural modifications must be simulated in software to be validated before being implemented; this was the option of Madeira International Airport, which thus seeks solutions to keep congestion levels under control, increase the efficiency of the terminal, and raise the level of passenger satisfaction.
- Spanish airports performance and efficiency benchmarkPublication . Martinez Ferrer, Pablo; Baltazar, Maria Emilia; Silva, J.This study uses a MCDA tool to analyse and improve Spanish airports performance and efficiency. Thus, a holistic study using MACBETH (with PESA-AGB) is used. This study has never been applied before in Spanish airports. Firstly, a literature review related to this study keywords is conducted, as well as about benchmarking concept applied specifically to airports. Secondly, several methodologies in used to benchmark airports are reviewed and compared. Thirdly, airport performance and efficiency issues are addressed and described. Finally, the MCDA-MACBETH (with PESA-AGB) tool is applied to 4 Spanish airports. Spanish airports belonging to AENA transported 263,753,406 passengers in 2018 with an increase compared to 2017 of 5.8%. General data enables to conclude that Spanish air transportation system is growing annually and hence there is the need to improve airports performance and efficiency, also to maintain the high levels of quality to address the growing demand. Spanish air transportation system is growing annually and is it upmost important to maintain high levels of quality to address such demand. Through this study, performance and efficiency improvements are seek within several airport key areas such as Safety and Security, Quality Service, Productivity and Effectiveness, Financial and Environment. As far as known, this study has never been applied before in Spanish airports.
- The concept of aerotropolis applied to a medium-sized city and its airportPublication . Carmo, João Jóia do; Silva, Jorge; Baltazar, Maria EmiliaMovements in Faro airport have been on a constant rise even exceeding the airport capacity. Faro city has grown in the same proportion. Both occurred in a pattern that can be applied to compare with the development of an Aerotropolis. At least three steps must be taken to develop an effective Aerotropolis plan. First, the catchment area is determined based on the existing transportation network and 60-minute travel time from the airport. Second, several socioeconomic indicators within the catchment area are evaluated through different periods using GIS software. Third, catchment area and socioeconomic indicators for the Faro region are compared with layouts obtained from several examples of Aerotropolises in Europe. The Aerotropolis model created by John Kasarda has been used in several regions across Europe. One key aspect of this model is determining whether the region evolved along with the airport throughout the years. Faro, its airport and surrounding areas, are not an exception. Thus, it is possible to identify Faro development patterns of growth useful for several stakeholders: administrative authorities, airport authorities, and territory planners. Faro airport movements have been on a constant rise. Faro city has grown, probably, in the same proportion. Both growths can be compared with an Aerotropolis development. Identifying development patterns of growth will be useful for: those responsible for the distribution of services in the territory; those who oversee the airport operation and expansion; those who are responsible for combining the interests of all for the regional development.
