A good system will greatly reduce the cost of training men as well as cut down on casualties. Several systems have been tried and are now in use. Among them are two that are worthy of more study. These are the CCTV or model board and the digital systems. Both have several disadvantages that create a need for a new system. One such system is an optically based digitally processes system that combines the best features of two previous systems. This system uses charge-coupled-device memories that are digitally accessed by a microcomputer based system. The information from the CCD's is then processed and calculations are performed on it to transform it into a form that can be displayed on a cockpit-like screen. The system also allows for interaction between the pilot and itself.

THE ROLE OF DOMAIN EXPERTISE AND JUDGMENT IN DEALING WITH UNEXPECTED EVENTS.
Creator
Kochan, Janeen, Jentsch, Florian, University of Central Florida
Abstract / Description
Unexpected events, particularly those creating surprise, interrupt ongoing mental and behavioral processes, creating an increased potential for unwanted outcomes to the situation. Human reactions to unexpected events vary. One can hypothesize a number of reasons for this variation, including level of domain expertise, previous experience with similar events, emotional connotation, and the contextual surround of the event. Whereas interrupting ongoing activities and focusing attention...
Show moreUnexpected events, particularly those creating surprise, interrupt ongoing mental and behavioral processes, creating an increased potential for unwanted outcomes to the situation. Human reactions to unexpected events vary. One can hypothesize a number of reasons for this variation, including level of domain expertise, previous experience with similar events, emotional connotation, and the contextual surround of the event. Whereas interrupting ongoing activities and focusing attention temporarily on a surprising event may be a useful evolutionary response to a threatening situation, the same process may be maladaptive in today's highly dynamic world. The purpose of this study was to investigate how different aspects of expertise affected one's ability to detect and react to an unexpected event. It was hypothesized that there were two general types of expertise, domain expertise and judgment (Hammond, 2000), which influenced one's performance on dealing with an unexpected event. The goal of the research was to parse out the relative contribution of domain expertise, so the role of judgment could be revealed. The research questions for this study were: (a) Can we identify specific knowledges and skills which enhance one's ability to deal with unexpected events? (b) Are these skills "automatically" included in domain expertise? (c) How does domain expertise improve or deter one's reaction and response to unexpected events? (d) What role does judgment play in responding to surprise? The general hypothesis was that good judgment would influence the process of surprise at different stages and in different ways than would domain expertise. The conclusions from this research indicated that good judgment had a significant positive effect in helping pilots deal with unexpected events. This was most pronounced when domain expertise was low.

Show moreThe Longbow Crew Trainer (LCT) is a cost effective, safe alternative to live training in the AH-64D/E Apache helicopter. Current Army doctrine and regulations have provisions for the limited use of simulator in lieu of aircraft hours toward semiannual minimum flight hour requirements. With the defense budget in decline, the Army must find innovative, cost effective methods to conduct realistic, relevant training to sustain proficiency in their warfighting capabilities. The LCT fully replicates the cockpit environment through training scenarios for requisite crew tasks and missions in a realistic, modular, and transportable solution. An attack helicopter crew can safely train in customizable scenarios ranging from basic aviation tasks to crew-level missions and gunneries. The Army is currently aligning one LCT per attack battalion under the Aviation Restructure Initiative. There are 20 Armed Reconnaissance Battalions/Squadrons in the active component with approximately 35 aircrews per battalion. The premise of this study was to review cost benefits of training in a virtual environment over a live environment while exploring the effects on proficiency. The difference in cost per hour between an AH-64D and the LCT is approximately $3,998. Using this figure and the semiannual flight hour requirements from the current Aircrew Training Manual in a weighted average between Flight Activity Category (FAC) 1 and FAC 2 pilot's flight minimum requirements formed the basis for four models: Low, Status Quo (baseline), Moderate, and High Virtual Simulation Models. This study found that while the High Virtual Simulation Model resulted in the greatest cost savings, the current budget and previous literature does not require such drastic measures. The Low Virtual Simulation Model resulted in higher costs. Therefore, the Moderate Virtual Simulation Model, proved most relevant to budget analysts, aviation unit commanders, and pilots by decreasing annual costs by an estimated $76.2 million without degrading proficiency.

Abstract / Description
Equivalency analysis is a statistical procedure that can enhance the findings of an analysis of variance in the case when non-significant differences are identified. The demonstration of functional equivalence or the absence of practical differences is useful to designers introducing new technologies to the flight deck.

Show moreEquivalency analysis is a statistical procedure that can enhance the findings of an analysis of variance in the case when non-significant differences are identified. The demonstration of functional equivalence or the absence of practical differences is useful to designers introducing new technologies to the flight deck. Proving functional equivalence is an effective means to justify the implementation of new technologies that must be (")the same or better(") than previous technology. This study examines the functional equivalency of three operational modes of a new active control sidestick during normal operations while performing manual piloting tasks. Data from a between-subjects, repeated-measures simulator test was analyzed using analysis of variance and equivalency analysis. Ten pilots participated in the simulator test which was conducted in a fixed-base, business jet simulator. Pilots performed maneuvers such as climbing and descending turns and ILS approaches using three sidestick modes: active, unlinked, and passive. RMS error for airspeed, flight path angle, and bank angle were measured in addition to touchdown points on the runway relative to centerline and runway threshold. Results indicate that the three operational modes are functionally equivalent when performing climbing and descending turns. Active and unlinked modes were found to be functionally equivalent when flying an ILS approach, but the passive mode, by a small margin, was not found to be functionally equivalent.

Abstract / Description
Improvisation is a construct that uses a set of minimal heuristic guidelines to create a highly flexible scaffold that fosters extemporaneous communication. Scholars from diverse domains: such as psychology, business, negotiation, and education have suggested its use as a method for preparing professionals to manage complexity and think on their feet.

Show moreImprovisation is a construct that uses a set of minimal heuristic guidelines to create a highly flexible scaffold that fosters extemporaneous communication. Scholars from diverse domains: such as psychology, business, negotiation, and education have suggested its use as a method for preparing professionals to manage complexity and think on their feet. A review of the literature revealed that while there is substantial theoretical scholarship on using improvisation in diverse domains, little research has verified these assertions. This dissertation evaluated whether improvisation, a specific type of dramatic technique, was effective for training pre-service teachers in specific characteristics of teacher-child classroom interaction, communication and affective skills development. It measured the strength and direction of any potential changes such training might effect on pre-service teacher's self-efficacy for teaching and for implementing the communication skills common to improvisation and teaching while interacting with student in an inclusive classroom setting. A review of the literature on teacher self-efficacy and improvisation clarified and defined key terms, and illustrated relevant studies. This study utilized a mixed-method research design based on instructional design and development research. Matched pairs t-tests were used to analyze the self-efficacy and training skills survey data and pre-service teacher reflections and interview transcripts were used to triangulate the qualitative data. Results of the t-tests showed a significant difference in participants' self-efficacy for teaching measured before and after the improvisation training. A significant difference in means was also measured in participants' aptitude for improvisation strategies and for self-efficacy for their implementation pre-/post- training. Qualitative results from pre-service teacher class artifacts and interviews showed participants reported beneficial personal outcomes as well as confirmed using skills from the training while interacting with students. Many of the qualitative themes parallel individual question items on the teacher self-efficacy TSES scale as well as the improvisation self-efficacy scale CSAI. The self-reported changes in affective behavior such as increased self-confidence and ability to foster positive interaction with students are illustrative of changes in teacher agency. Self-reports of being able to better understand student perspectives demonstrate a change in participant ability to empathize with students. Participants who worked with both typically developing students as well as with students with disabilities reported utilizing improvisation strategies such as Yes, and..., mirroring emotions and body language, vocal prosody and establishing a narrative relationship to put the students at ease, establish a positive learning environment, encourage student contributions and foster teachable moments. The improvisation strategies showed specific benefit for participants working with nonverbal students or who had commutation difficulties, by providing the pre-service teachers with strategies for using body language, emotional mirroring, vocal prosody and acceptance to foster interaction and communication with the student.Results from this investigation appear to substantiate the benefit of using improvisation training as part of a pre-service teacher methods course for preparing teachers for inclusive elementary classrooms. Replication of the study is encouraged with teachers of differing populations to confirm and extend results.
