14. Parâmetros para o projeto de poltronas aeronáuticas : revisão da literatura e as práticas da indústria no setor de transportes
The comfort issue has gained increasing relevance in aircraft cabin projects, and has become a key variable in studies of passengers propensity to take flights as well as an advantage in a competitive market. Among different variables that can influence the passengers comfort perception, those concerning the seats seem to have great relevance. The initial ai

15. F-5M DTA Program
Abstract: The Brazilian F-5 was submitted to avionics and weapons upgrade. This "new" aircraft has proven to be heavier and more capable. A comprehensive damage tolerance analysis is being performed to evaluate how the new mission profiles and weight distribution may affect the airframe structural integrity. Operational data were collected at the Brazilian A

16. Análise dos modelos para cálculo de níveis de segurança relacionados à operação de veículos aéreos não tripulados. / Analysis of models for calculation of levels of security related to operation of unmanned aerial vehicles.
There are records of the use of Unmanned Aerial Vehicles (UAVs) used for military activities since the beginning of the 20th century. But that is not the only way to use it; the civil environment is also promising as to the use of this kind of aircraft. More studies and validations have to be performed about the alterations in the safety levels with the inte

17. Desenvolvimento e avaliação de estratégias de assistência à pilotagem para aeronaves leves
The following work presents the process of choice and development of a series of strategies to facilitate piloting on light aircrafts. These strategies are based on trajectory control instead of attitude control like it is usually done in conventional aircrafts, aiming smaller learning times as well as reduction in pilot workload, such that flight safety is

19. Heat and mass transfer in two-phase flow around airfoils with aeronautical anti-ice systems. / Transferência de calor e massa no escoamento bifásico em torno de aerofólios equipados com sistemas de antigelo aeronáuticos.
It is required to prevent ice accretion on wings and horizontal stabilizers because it may cause aerodynamic performance degradation, weight increase, flight control difficulties and, in critical cases, may lead to operational safety margins reduction. When aircraft flies through clouds containnig supercooled water droplets, which are in metastable equilibri

20. Relationship between Brazilian airline pilot errors and time of day
Flight safety is one of the most important and frequently discussed issues in aviation. Recent accident inquiries have raised questions as to how the work of flight crews is organized and the extent to which these conditions may have been contributing factors to accidents. Fatigue is based on physiologic limitations, which are reflected in performance defici

21. Aircraft safety assessment process enhanced by human factors aspects.
Flight Safety is nowadays one of the concerns of global aviation community and is relevant to the survival of the aeronautical industry. In this context, expansion of human factors awareness presents a significant opportunity to make aviation safer, since the human / machine interface is a frequent source of error. This work analyzes the human interface with

22. Monitoração da trajetória em tempo-real de veículos espaciais: suporte na tomada de decisão pela segurança de vôo / Space vehicle trajectory monitoring in real time: support to decision making for flight safety group
Whenever satellites or scientific experiments are launched from vehicles, it is more than natural that the successful accomplishment of the mission is of interest to all the involved parties. In such activities, several teams with determined targets contribute as participating members. In terms of safety, the Flight Safety (SVO) team is responsible for this

23. Monitoração da trajetória em tempo-real de veículos espaciais: suporte na tomada de decisão pela segurança de vôo / Space vehicle trajectory monitoring in real time: support to decision making for flight safety group
Quando veículos com satélites ou simplesmente com algum tipo de experimento científico são lançados ao espaço, o dever de se cumprir a missão à que o veículo foi destinado, é interesse de todas as entidades envolvidas. Porém, neste tipo de atividade, existem várias equipes que participam do projeto, e cada uma tem a sua meta a cumprir. Assim, em

24. Ergonomia na aviaÃÃo: um estudo crÃtico da responsabilidade dos pilotos na causalidade dos acidentes
Oficial documents about aviation accidents always attribute the responsability to pilots or on a combined cause participation with others causes as environment or methereological factor at a proportion near 80%. We must consider that the pilot receives the machine that begins its design years before. Now he has the obligation to mantain this artefact flying,
