Safe and efficient training using flight simulation training devices (FSTD) is one of the fundamental components of training in the commercial, military, and general aviation. When compared with the live training, the most significant benefits of ground trainers include improved safety and the reduced cost of a pilot training process. Flight simula...

... we consider two main application areas of FSTD: (1) training; and (2) system engineering (research). Graphical representation of the major FSTD applications categories is given in Fig. 2, while the literature used in this Section is systematically listed in Table 1 according to areas of FSTD usage. ...

... Like some flight simulators [8,9,10] medical virtual environments provide a well-monitored and safe method of surgical staff training. Students and surgeons can learn new skills and training difficult and complex surgical procedures. ...
Laparoscopic surgery is very popular medical intervention for diagnoses and treatment of same abdominal diseases. The procedures are performed using long thin tools that are inserted through a trocar in the human body. The surgeon orients the instruments by laparoscopic images displayed on a monitor. Environment is uncertain (highly dynamic) with limited work space. The surgeon must adapt to the instruments' specifics. Guiding such an instrument is difficult and requires a lot of training and practice. This article is related to early design of a mechatronic device prototype, which main target is training of surgical skills in medical students using concepts of Medical Mechatronics and Robotics, thus will be preparing future surgeons and advanced technologies will be introduced in Surgical area.
... Active G-training has the potential to provide a realistic platform where pilots can safely practice dangerous scenarios at a much lower cost [8,10]; G-suits or G-seats are an alternative [11,12]. Ref. [13] provides a comprehensive review of research carried out in Dynamic Flight Simulators (DFS) and its usefulness in various simulation scenarios. ...
When coupled with additional degrees of freedom, centrifuge-based motion platforms can combine the agility of hexapod-based platforms with the ability to sustain higher G-levels and an extended motion space, required for simulating extreme maneuvers. However, the false and often nauseating sensations of rotation, by Coriolis effects induced by the centrifuge rotation in combination with rotations of the centrifuge cabin or the pilot's head, are a major disadvantage. This paper discusses the development of a motion filter, the Coherent Alignment Method (COHAM), which aims at reducing Coriolis effects by allowing small mismatches in the G-vector alignment, reducing cabin rotations. Simulations show that as long as these mismatches remain within a region where humans perceive the G-vector as 'coherent', the Coherent Alignment Zone (CAZ), the cabin angular accelerations can indeed be reduced. COHAM was tested in a high G-maneuver task with a fixed CAZ threshold obtained in a previous study. It was experimentally compared to an existing motion filter, using metrics such as sickness, comfort and false cues. Results show that sickness, dizziness and discomfort are reduced, making the centrifuge sessions more bearable. It is recommended to further improve the filter design and tuning, and test it with more fighter pilots.
Goal: The purpose of the research is to apply a method of decision support to prioritize flight simulators of the Air Force Command in view of the country”s budget constraints in the defense sector. Methodology: The research was performed with the Analytic Hierarchy Process (AHP), associated with hypothesis tests to define the preference or equivalence relationships between the simulators. Data collection involved the support of 32 Air Force specialists with extensive experience in the chosen simulators. Results: The T-27 Tucano simulator was preferred, followed by the C-95M Bandeirantes and the C-105 Amazonas, which obtained statistical similarity to each other. In fourth place was the A-29 Super Tucano simulator. The two simulators that had the least preference were the F-5M Tiger II and the A-1 AMX, which achieved results that were statistically close to each other. Limitations: Any multicriteria decision aid technique embeds its features and limitations. This is not exclusive to AHP, although the consistency ratio is a differential in relation to other methods. The expert sample also reflects the preferences of a group, with reservations to the generalization of the results. Practical implications: The findings of this research can be used in practice, by assisting the Brazilian Air Force in applying its scarce financial resources to prioritize flight simulators. Originality / Value: The research is unique to the Brazilian Air Force, in particular to the Center that oversees flight simulators, and is also relevant in including hypothesis testing to AHP results.
