This study aims at explaining the deviation between the budget balance ratio forecasts and the outcomes in the Portuguese official forecasts and in the European Commission (EC) vintage forecasts. Therefore, we used data from the EC for the period 1969-2011 and also the Portuguese official...

The performance of an airport and its efficiency has been measured generally from its operational and financial data, and on that basis, classified its relative position in the set of airports. But this methodology, by itself, is insufficient to determine relationships between a given position...

Cross-border regional development is one of the EU current major concerns. These regions are usually less dynamic socio-economically. Some of them have recently benefited from new roads, which have mainly been funded through the European financial program of Transnational Transport Networks,...

Airport benchmarking depends on airport operational performance and efficiency indicators, which are important issues for business, operational management, regulatory agencies, airlines and passengers. There are several sets of single and complex indicators to evaluate airports performance and...

All over the world there are several countries where airships are being used for military and civilian purposes. The rebirth of this mean of transportation, capable of easily overcoming some deficiencies of the conventional ones, brings medium and long term economic benefits. In addition, they...

Light aviation pilots are exposed to many different environmental situations due to non-pressurized aircraft cabins. Those variations can push the human body to some limits, which associated with psychological factors may culminate in incidents or even fatalities. Really, a literature review on...

The measure of an airport performance and its efficiency is generally made using operational and financial data, thus providing a position rank in respect to a set of airports. But this methodology, by itself, cannot provide the true relationships between a certain position in the rank of an...

The majority of light aviation aircrafts cabins are unpressurised and this may pose risks for the safety of both pilots and passengers. As altitude increases partial oxygen pressure decreases and this situation may lead to early stages of hypoxia affecting pilot’s capabilities to perform...

Cross-border regions’ development is one of the EU major current concerns. These regions are usually less dynamic socio-economically and correspond to peripheral areas within each country. Some of these regions have recently benefited from the existence of new roads, which investment...
