- As Ocupações Pós-Governativas dos Ministros e Secretários de Estado em PortugalPublication . Freire, Diogo Pessoa; Silveira, Pedro Miguel AlegriaHá a perceção de que os ex-governantes saem do governo para carreiras altamente lucrativas no setor privado. Mas será que é uma perceção correta? Será que as ocupações pós-governamentais dos ex-governantes passam por uma carreira no setor privado, com cargos de alta senioridade e que a pasta que detêm no governo influencia futuras ocupações dos mesmos? Esta dissertação pretende responder a estas perguntas, com especial foco nos Governos XIX e XXI Constitucionais Portugueses. Para esta dissertação propomo-nos a mapear as ocupações pós-governamentais dos ex-ministros e secretários de estado desde o primeiro ano após o término do cargo e após três anos, de forma a perceber potenciais padrões. As conclusões demonstram que as ocupações pós-governamentais dos ex-governantes são sobretudo no setor público, geralmente em cargos de média senioridade, e não demonstram uma ligação com as áreas de responsabilidade ministerial previamente exercidas, tornando o caso português, um caso particular, em relação à literatura.
- Development of new Water Landing Infrastructures and ProceduresPublication . Gabriel, Vasco João Capote; Silva, Jorge Miguel dos Reis; Soares, Paulo Alexandre Ramos de FigueiredoThis Master Dissertation arises from an analysis of accidents in Portuguese territory involving water landing and ditching emergencies. The concern regarding this topic was primarily raised by Gabinete de Prevenção e Investigação de Acidentes com Aeronaves e de Acidentes Ferroviários (GPIAAF). Over the past years, Portugal has experienced several accidents of this type, some fatal, which involved or should have involved an in-depth study of the process of water landing and its specificities. It is therefore evident that there is a failure regarding the characteristics of the dedicated water landing infrastructures, as well as an effective risk assessment and flight crew training related to this aspect. This Master Dissertation not only addresses an analysis of historical occurrences, and the lessons retrieved up from them but also the current applicable regulations, to make possible to propose new water landing infrastructures equipped with operational support elements that could assist aircrafts in regular operations as well as emergency situations, if the decision is to ditch the aircraft. For this purpose, two locations are proposed for such infrastructures at two distinct dams, Marateca and Aguieira, being the first near Castelo Branco and the latter on near Viseu. The proposed location of these infrastructures is based on the initial condition that the areas for operation are well defined and marked out, thus avoiding the risk of incursion into them by third parties who are unaware of the delimitation of these restricted areas of operation. It also accounts for the existence of means of rescue, not only for normal operations, but especially in the event of an accident, namely search and rescue means for immediate reaction. It is also proposed to build up the infrastructure on the ‘land side’ with hangars, parking bays and taxiways, which can be used by amphibious or rotary-wing aircraft, while aircraft/crews can move from the maritime to the land environment via docks or access ramps. Moreover, access roads, suitable car parking slots, and restaurants, for example, can have a double-use, for both complementary aerial emergency activities and for tourism purposes, for example. Means for ensuring safety and separation of “airside” to the “landside” are also proposed. This entire study is based on current regulations to ensure the necessary safety and compliance. To ensure that the proposed infrastructure is operation viable, it will be necessary to provide for the most rigorous risk assessments possible, which in terms of crew training will lead to the implementation of new training methods, not only in the theoretical component, but mainly in terms of instruction and flight training, which should be transversal to any Approved training Organisation (ATO). This study is based on the requirements of international and national legislation, which include theoretical and practical training, as well as key points that must be addressed during the training stage. In addition, these points are based on the prerequisites needed to obtain an amphibious aircraft pilot's licence. For this study, and while developing this dissertation, only the crucial flight phases involving the use of the proposed infrastructure have been considered.
