A case study assessment of operational effectiveness for an advanced helicopter flight simulator : the CH146 tactical helicopter mission simulator

Flight simulators are widely used for training in both military and civil aviation, and the scope of applications in simulation has expanded widely during approximately the last three decades. A fundamental question in the effective application of this technology is the extent to which training in a simulator constitutes adequate preparation for actual flight. The process of validation of simulator effectiveness is as yet not well defined, and the common, though mistaken, association of high fidelity with high training effectiveness clouds the determination of the degree of fidelity required to achieve specific training objectives. It is axiomatic in simulation that no ground-based training device can achieve perfect fidelity, and the present state of the art is such that incremental improvements in fidelity will yield diminishing returns in training effectiveness. Far greater benefits can be realized from attention to more effective utilization of the existing systems. This thesis details the difficulties inherent in the determination of training effectiveness for a mission simulator. Experience with a specific military simulator acquisition project, the Canadian Forces\u27 CHI46 Griffon tactical helicopter mission simulator, is used in this paper to highlight the challenges inherent in validating simulator training effectiveness; particularly that of a tactical full-mission simulator. The author\u27s experience indicates that the key limitations to achieving optimum training effectiveness lie not in maximizing the fidelity of the simulation, but in knowing how to effectively exploit its existing capabilities. Challenges remain in the areas of validation, syllabus design, instructional technique and user interface. The effective use of training technology has become of critical importance, given the technical sophistication of modern simulators. The understandable desire to extract maximum utilization from simulators has led to suboptimal use of very expensive investments

Applying Research-Based Training Principles: Towards Crew-Centered, Mission-Oriented Space Flight Training

This chapter describes a training approach that applies empirically derived principles of training to re-imagining the overall design of NASAs space flight training program. The chapter is focused specifically on the design of astronaut training for NASAs future deep space, exploration missions to Mars. We briefly describe NASAs space flight training practices during the Apollo and Space Shuttle eras as well as NASAs current practices for training astronauts for their missions to the International Space Station. We provide an overview of NASAs current concepts for a mission to Mars to scope our training approach. We envision a new space flight training approach which we term crew-centered, mission oriented training, inspired by the design approach offered in the context of airline pilot training by Barshi (2015). We apply some of the training principles reviewed by Kole and his colleagues in the companion volume (Kole, Healy, Schneider & Barshi, 2019), as well as by other researchers in training science (e.g., Ericsson, Krampe, & Tesch-Rmer, 1993; Healy & Bourne, 2012; Salas, Wilson, Priest and Guthrie, 2006), into real-world, practical guidelines for the particular context of training astronauts for a mission to Mars.processes over very long retention intervals

A Framework for Delivering Contextually Appropriate Opportunities for Warfighter Practice

Computer-based modeling and simulation has been a training staple in the military domain since the first aircraft simulators were adopted. More recently, virtual environments based on modeling, simulation and serious games, have introduced relatively low-cost, yet high value additions to the learning environment. As these virtual environments have proliferated, many researchers have investigated the relationship between theoretical foundations of learning, learner development and content delivery, and applied their findings in an attempt to bolster learning, yet performance deficiencies continue to exist. This study asserts that performance deficiencies exist in part because of insufficient contextually appropriate opportunities to practice. This work is multi-disciplinary in nature. Its foundation is modeling and simulation engineering; the use of technology to deliver training. Educational psychology and human factors concepts explain the theoretical basis for modeling and simulation as an effective training delivery agent. The study\u27s thesis is that a framework for delivering contextually appropriate opportunities for warfighter practice can be applied to discover whether modeling, simulation and game-based virtual environments have the potential to improve individual performance for learners beyond the Novice Stage (e.g., Competent Stage) of skills acquisition. Furthermore, this conceptually appropriate practice (CAP) framework can be used to assess the potential of low fidelity virtual environments to provide targeted practice and to improve individual performance, not only during training in high-fidelity virtual environments (near transfer) but also in the live environment (far transfer). To evaluate the thesis, this study investigates the relationship of technology and learning science, and features an empirical evaluation of training effectiveness afforded by delivering additional training repetitions using both low-fidelity virtual environment simulator systems and high-fidelity aircraft simulators

Space Exploration Systems, Strategies and Solutions

The present thesis describes the PhD research activities dealing with the topic “Space Exploration Systems, Strategies and Solutions”. Traveling beyond low Earth orbit is the next step in the conquest of the solar system and so far, a human expedition to Mars is considered the most interesting goal of future human space exploration. Due to the technological and operational challenges associated with such a mission, it is necessary to define an opportune path of exploration, relying on many missions to intermediate and “easier” destinations, which would allow a gradual achievement of the capabilities required for the human Mars mission. The main scope of this research has been the development of a rigorous and versatile methodology to define and analyze evolutionary exploration scenarios and to provide a detailed technologies’ database, to support strategic decisions for human space exploration. The very innovative aspect of this work regards the development of a flexible methodology which can be followed to assess which are the next destinations for the exploration of space beyond LEO and to preliminarily define mission’s architectures, identifying the most significant needed elements and advanced technologies. The obtained results should be seen as a pure technical reference, as no cost and/or political considerations have been included, and can be exploited to opportunely drive the decisions of the agencies to place investments for the development of specific technologies and get ready for future exploration missions. The first part of the work has been devoted to the definition of a reference human space exploration scenario, which relies on both robotic and human missions towards several destinations, pursuing an increasing complexity approach and looking at a human expedition to Mars as final target. The scenario has been characterized through the assessment of the missions and the relative phases and concepts of operations. Accordingly, the needed space elements, or building blocks, have been identified. In this frame, the concept design of two specific elements has been performed: the first is a pressurized habitation module (Deep Space Habitat) for hosting astronauts during deep space missions; the second is an electrical propulsive module (Space Tug), mainly envisioned for satellites servicing. The last part of the work has focused on the analysis of innovative and enabling technologies, with particular attention to the aspects related to their on-orbit demonstration/validation, prior to their actual implementation in real exploration missions. The PhD has been sponsored by Thales Alenia Space - Italy and the overall work has been performed in different frameworks along the three years, as well as participating to several additional activities. In line with the objectives of the PhD, in 2012 a collaboration between Politecnico di Torino and Massachusetts Institute of Technology has been established (MITOR Project, managed by MIT-Italy Program), with the support of Thales Alenia Space as industrial partner. The MITOR project, titled “Human Space Exploration: from Scenario to Technologies”, has been aimed at identifying and investigating state of the art for Human Space Ex- ploration, enabling elements, subsystems and technologies with reference to a selected scenario and relevant missions and architectures. Part of the nine months activities has been carried out at MIT AeroAstro department. Besides MITOR project, the PhD activities have been carried out in synergy with some other research programs, such as ESA “Human Spaceflight & Exploration Scenario Studies” and STEPS2 project (Sistemi e Tecnologie per l’EsPlorazione Spaziale - phase 2). Furthermore, in 2013 a specific study has been performed in collabora- tion with university “La Sapienza” (Rome), “Osservatorio Astrofisico di Torino” (Astrophysical Observatory of Torino) and DLR (Deutsches Zentrum fr Luft- und Raumfahrt) in Bremen; its main objective has been the analysis of an interplanetary cubesats mission, aimed at space weather evaluations and technologies demonstration

A STUDY OF FLIGHT SIMULATION TRAINING TIME, AIRCRAFT TRAINING TIME, AND PILOT COMPETENCE AS MEASURED BY THE NAVAL STANDARD SCORE

The purpose of the study was to investigate the relationships between US Navy T-45C flight simulation training time, actual aircraft training time, and intermediate and advanced jet pilot competence as measured by the Naval Standard Score (NSS). Examining the relationships between US Navy T-45C flight simulation time and actual aircraft flight time may provide further information on flight simulation training versus actual aircraft training to aviation authorities, flight instructors, the military aviation community, the commercial aviation community, and academia. The study was non-experimental, correlational, causal-comparative with an emphasis upon the establishment of mathematic and predictive relationships using archival data from the Chief of Naval Air Training (CNATRA) Training Information System (TIMS) database. CNATRA aircraft hours, flight simulation hours, and NSS scores of intermediate and advanced flight students from 2015 to 2017 were analyzed and compared. Actual aircraft time was found to be a significant predictor of NSS scores for both intermediate and advanced pilot trainees. Implications of the study include recommendations for future research and strategies to improve flight simulation in pilot training

Flying green from a carbon neutral airport : the case of Brussels

The aviation sector is one of the fastest growing emitters of greenhouse gases worldwide. In addition, airports have important local environmental impacts, mainly in the form of noise pollution and deterioration in air quality. Although noise nuisance in the vicinity of airports is recognized as an important problem of the urban environment which is often addressed by regulation, other environmental problems associated with aviation are less widely acknowledged. In the climate debate, the importance of which is rising, aviation has remained under the radar for decades. In the present paper, we use the case of Brussels Airport (Belgium) to demonstrate that the local perception of air travel-related environmental problems may be heavily influenced by the communication strategy of the airport company in question. Basing our analysis on publicly available data, communication initiatives, media reports, and policy documents, we find that (1) the noise impact of aviation is recognized and mainly described in an institutionalized format, (2) the impact of aviation on local air quality is ignored, and (3) the communication on climate impact shows little correspondence or concern with the actual effects. These findings are relevant for other airports and sectors, since the type of environmental communication produced by airport companies can also be observed elsewhere
