Purpose: Urban mobility is all about people as well as the climate change issue is a human issue. Thus, this research envisions to provide conditions and practical tools through the innovation in urban mobility by bringing urban air mobility (UAM) to cities worldwide, contributing to change lives for the better and reversing the global issue of cli...

The research aims to propose a methodology to estimate the reliability of the Brazilian airport network (domestic passenger traffic), based on the centrality of airports (Network Theory). The applied methodologies are related to Network Theory, a branch of Graph Theory, and reliability. Reliability is associated with the good functioning of a produ...

Purpose: This research aims to investigate the relation between urban logistics and all delivery systems used. The unmanned aerial vehicle (UAV) and the unmanned aerial system (UAS) have been under investigation in the world of logistics, having been pointed as the next logistic technology. For that reason, this article proposes the use of UAV in u...

Purpose: Air transport is a highly regulated branch of aviation, but it continues to show occurrences where human error is present. Fatigue is now recognized as a hazard which degrades human performance and can put flight safety at risk. In this regard, the general objective of this study is to assess the impact of cognitive fatigue on airline pilo...

A administração é uma área multifacetada, composta por diversos pilares que se complementam, proporcionando maior previsibilidade nos resultados a serem alcançados, bem como contribuem para a melhor tomada de decisão, no momento certo. A realidade apresentada ao mundo pela pandemia do Corona Vírus, trouxe desafios e contingências que, seriam possív...

Purpose: The article aims to show the viability of installing a precision-based approach system in Viseu airfield, in Portugal. This work looks to evidence to what extent the implementation of ILS (Instrument Landing System) or GBAS (Ground Based Augmentation System) in the airfield is viable, and which of the two would be the better option for thi...

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 specifical...

Airport benchmarking depends on airport performance and efficiency indicators, and it is an important issue for business, operational management, regulatory agencies, airlines and passengers. Using the MACBETH (Measuring Attractiveness by a Categorical Based Evaluation Technique) approach, a hierarchical additive value model is constructed with cri...

Due to the deregulation of the airline market in Europe, LCC’s have shown a fast growth in the last decade. This change in airline market has affected the way many airports operate and it’s expected that this impacts not only in airport performance, but also in its hinterland. Tourism development is one of the main beneficiaries of this new paradig...

Due to airline market deregulation in Europe LCC’s (Low-Cost Carriers) depicts a fast growth in the last decade and it’s expected that this growth continues in the next years. Also, this European airline market change has affected the way many airports operate and it’s likely that this change impacts not only airports performance and efficiency, bu...

The air transport has suffered a remarkable transformation over the past decade. The way we travel today is quite different from how we did ten years ago. Due to the rise of low cost carriers, the market of air transportation has been constantly changing and presently witnessing the transformation of legacy carriers in order to manage to continue o...

The most common location for campsites is in forested or arborous areas. Given the regular use of combustible material by campers and the frequent use of campfires to cook, campsites become areas with a high propensity for the occurrence of fires. Moreover, fires occurring close to campsites can cause evacuations, disturbing their regular activitie...

The growth of the low-cost carriers (LCC’s) change how airports are manage and their performance. This study focus on the literature review of the low-cost carriers growth, airport performance, multiple-criteria decision analysis (MCDA) and future work. In this study we model the airport key performance areas and key performance indicators in a mu...

The utility of the airport benchmarking process is widely recognized in a world where competition among airports is becoming more than ever a reality. Therefore there is a need for a wide consensus to establish and construct reliable databases for measuring airport performance and consequently to evaluate the development and the implementation of e...

The common location of camping parks in forested or wooded areas, the normal use of combustible material by the campers and the frequent use of campfires to cook turn camping parks into areas with a high propensity for the occurrence of fires. Moreover, fires occurring close to parks induce to evacuations that disturb their normal activities. Despi...

One of de EU major concerns is cohesion and cross-border regional development. Usually cross-border regions are less dynamic, acting as bottlenecks mainly in peripheral territories. This paper is focused on the Portuguese-Spanish border using socio-economic and accessibility data. It considers Spatial Econometrics to produce statistical evidence on...

The general aim of this work is the development of airports performance and efficiency predictive models using robust but flexible methodologies, and incorporating traditional indicators as well as new constraints. Particularly it shows and compares the efficiency evolution of the same airport along several years, under several constraints, based o...

The present article aims to contribute for discussing alternatives for the sustainable development of supra-municipal platforms, which articulate sub-spatial units, at the city level. For accomplishing this, we explore a taxonomy of the spatial lifecycle, in order to reveal the necessity of creating an institutional platform among government, indus...

ADS-B is a very useful system to solve surveillance precision problems mainly if installation, operation and maintenance costs of alternative ones are too expensive when they are based on air traffic figures. This paper begins with some remarks about ADS-B technology, precisely to introduce the case study of Azores archipelago within Santa Maria FI...

This paper deals with the viability analysis of the implementation of RNAV and RNP AR approaches to Pico Island airport in the Azorean archipelago. The main objective is to prove that this new type of approach technology can be implemented in the Azorean islands airports in accordance with the ICAO rules providing an increase in safety and lowering...

With the beginning of XXI century airships has been seen as a complementary platform of air transportation systems in use capable to create new market niches and new productive sectors. Nowadays airships are intended for several applications such as: heavy cargo transportation, point-to-point transportation, advertising, aerial observation, patroll...

Technological developments and environmental concerns are among several reasons that are bringing up once again the concept of new air transportation vehicles like the airships. Nowadays airships have several applications such as: heavy cargo and point-to-point transportation, advertising, observation, patrolling and monitoring, research, and touri...

Nowadays the society is based on the people and goods mobility, so that results necessary guarantee the efficiency of the transportation system as accessibility and mobility in the territory. The history of tourism in a territory is tightly connected to the evolution of its transportation system; we can affirm that is not present a tourist place, a...

RESUMO Com base em dados publicados pela ICAO estima-se que em 2002, em todo o mundo, mais de 800 transportadoras aéreas tenham assegurado serviços regulares de transporte de passageiros, e que mais de 90 transportadoras aéreas tenham assegurado serviços regulares de transporte de mercadorias. Em 2002 o transporte regular das companhias aéreas pert...

Tourism and accessibilities are interlinked. On one hand tourism is a driving factor for and (often) a stimulator of change in accessibilities; on the other hand accessibilities themselves opened new touristic destination perspectives even helping to develop locally correlated new business models. Beira Interior is located close to the Spanish bord...
