Transfer of flight training from a Singer-Link GAT-2 training simulator, modified to approximate a counterpart Piper Cherokee Arrow airplane, was measured for independent groups of nine flight-naive subjects, each trained in one of three simulator cockpit motion conditions: normal washout motion in bank with sustained pitch angles, washout banking motion in which the direction of motion relative to that of the simulated airplane was randomly reversed 50% of the time as the cab passed through a wings-level attitude, and a fixed-base condition. Subjects received predetermined fixed amounts of practice in the simulator on each of 11 flight maneuvers drawn from the Private Pilot flight curriculum. Transfer performance measures, including flight time and trials to FAA performance criteria and total errors made in the process, showed reliable transfer for all groups with differential transfer effects and cost-effectiveness implications depending upon the type of simulator motion.

Performance of operator controlled systems is limited by our ability to measure system and component subsystem performance in a reliable and sensitive manner. Without adequate performance measures, there is no way to produce and test system designs, plan and execute training systems, or evaluate operational systems. Methods of developing these performance measures can be characterized by the way in which performance criteria are obtained. One approach which can be used when all factors that limit performance are known and quantified is an analytical method. For example, if a problem requires that an aircraft climb to a specified altitude while conserving fuel during the climb, the criterion, i.e., minimization of fuel, could be precisely defined analytically. Frequently, however, problems cannot be solved analytically, but demonstrations of superior as well as less than superior performances are available. In these cases an empirical approach can be used. This paper describes an empirical method for analyzing simulator flight data to develop weightings that permit performance discrimination between two groups of student pilots (one group of students successfully passed the initial Army rotary wing training program at Ft. Rucker, Alabama. The other group of students did not pass that training course.). The paper provides a description of the job sample (flight training) tests used to collect the data, the method for synthesizing the performance measures, and the results from using the measures to score student pilots.

The release of captive-raised parrots to create or supplement wild populations has been critiqued due to variable survival rates and unreliable flocking behavior. Private bird owners free-fly their parrots in outdoor environments and utilize techniques that could address the needs of conservation breed and release projects. We present methods and results of a free-flight training technique used for 3 parrot flocks: A large-bodied (8 macaws of 3 species and 2 hybrids), small-bodied (25 individuals of 4 species), and a Sun Parakeet flock (4 individuals of 1 species). Obtained as chicks, the birds were hand-reared in an enriched environment. As juveniles, the birds were systematically exposed to increasingly complex wildland environments, mirroring the learning process of wild birds developing skills. The criteria we evaluated for each flock were predation rates, antipredator behavior, landscape navigation, and foraging. No parrots were lost to predation or disorientation during over 500 months of free-flight time, and all birds demonstrated effective flocking, desirable landscape navigation, and wild food usage. The authors conclude that this free-flight method may be directly applicable for conservation releases, similar to the use of falconry methods for raptor conservation.

ABSTRACTThe trustees and sponsors of defined benefit schemes rely on the advice of the Scheme Actuary to make important decisions concerning the funding of the scheme, the investment of its assets, and the use of surplus assets to improve benefits. These decisions have to be made in the face of considerable uncertainty about financial and demographic factors that will affect the future experience of the scheme and its success in meeting various objectives.The traditional actuarial valuation combined with actuarial judgement has played an important role in guiding decision making; but we argue that stochastic methods can add value in certain crucial areas, in particular the financial risk management of defined benefit schemes. Rather than dealing with risk by incorporating margins in the valuation basis, a stochastic approach allows the actuary to evaluate specific and quantifiable risk and performance measures for alternative funding and investment strategies.This paper recommends a framework that, when combined with a suitable stochastic model, measures the risks inherent in contribution rate and asset allocation decisions, allowing better decisions to be made. In doing this, we suggest and apply various risk and performance measures that may be thought appropriate, although our intention is to illustrate their use rather than prescribe them as objective standards. The framework provides the means to explore the trade-offs involved in possible contribution and asset allocation decisions, and points to decision strategies expected to give improved outcomes for the same level of risk. A feature of the approach that marks it out from current asset/liability techniques is that it examines the funding and investment decisions together. It does not derive a contribution rate in the traditional way, but leaves this as free variable, in the same way that the investment decision is taken to be a free variable. Another distinctive feature of our framework is that it is based on projection rather than on valuation, involving stochastic simulation of the experience of the scheme over a time horizon reflecting the concerns of the trustees and the sponsoring employer.The paper provides a case study (based on a model final salary pension scheme) showing the advantages of the framework, and goes on to explain how the results may practically be communicated to trustees and scheme sponsors.

There is interest in how pilots perceive simulator fidelity and rate self-performance in virtual reality flight training. Ten participants were trained to perform a target tracking task in a helicopter flight simulation. After training objective performance, the median tracking error, was compared to subjective self-evaluations in a number of flying conditions where the cues available to our pilots were manipulated in a factorial design: the simulator motion platform could be active or static, audio cues signalling the state of the turbine could be those used during training, non-informative, or an obviously different but informative ‘novel’ sound. We tested participants under hard and easy flying conditions. Upon completion of each test condition, participants completed a 12-statement Likert-scale with items concerning their performance and helicopter simulator fidelity. Objective performance measures show that flight performance improved during training and was affected by audio and motion cues. The subjective data shows that participants reliably self-evaluated their own performance and simulator fidelity. However, there were instances where subjective and objective measures of performance or fidelity did not correlate. For example, although participants rated the ‘novel’ turbine sound as having low fidelity, it behaviourally caused no difference with respect to the turbine sound used in training. They were also unable to self-evaluate outcome of learning. We conclude that whilst subjective measures are a good indicator of self-performance, objective data offers a valuable task-oriented perspective on simulator fidelity.

The Situation Awareness Behavioral Rating Scale (SABARS) utilizes ratings by expert observer/controllers (O/Cs) to evaluate situation awareness (SA) of infantry small unit leaders. Previous research (Matthews et al., 2004) showed SABARS to be predictive of a variety of performance measures. The current study explored the question of whether small unit leaders could use SABARS to accurately rate their own behavior as an index of their SA. To evaluate this question, 12 Norwegian Army and Navy Academy cadets participating in the role of squad leader during summer training exercises were given the SABARS to complete following an infantry mission. An experienced officer O/C observed the cadets though the execution of the mission and also provided SABARS ratings on the squad leader. Results indicated that “self-SABARS” evaluations did not correlate with SABARS completed by O/C's, and were not predictive of performance criteria. O/C-completed SABARS were, however, predictive of performance criteria thus replicating findings reported previously (Matthews et al., 2004). Implications for assessing SA in the field are discussed.

And Training

Some claimed cost, safety, efficiency, and effectiveness advantages of aircraft simulators for training are equivocal. Effectiveness of simulator training depends mostly upon the training procedures. Other factors alleged to influence the effectiveness of simulators vary in their demonstrated importance. These are considered in the contexts of physical simulation vs. psychological simulation, simulator fidelity and motivation, and pilot acceptance. One of the more costly areas of engineering development to increase fidelity of physical simulation is motion systems. No experimental evidence is available to show that simulator motion enhances transfer of training. Cost effectiveness has not been demonstrated for many interesting and attractive features that are standard trimmings on flight training simulators. The acquisition of simulators costing several times as much to own and operate as their counterpart airplanes may produce a backlash that will set back the desirable use of cost-effective simulators in reasonable research and training programs.

The Impact

The instructional capability of the training simulator has improved in tempo with simulation technology. The business of shaping student behaviors has achieved a leap forward in efficiency due to digital computation and the computer display terminal. This paper discusses the impact of computer assistance on the capability for structuring and controlling synthetic flight training, and examines the instructional potential of the “new breed” of flight simulators presently on-line or in the developmental stage. A number of recent innovations in instructor station design is described. These developing, student-centered instructional techniques for promoting training effectiveness place the simulator quite realistically in contention as a major flight training medium of the future.

Different Types

The relative benefits of different types of flight training equipment were evaluated in a routine instructional situation with no particular constraints placed upon the instructor as to how he used the equipment and without interfering with the normal course of flight training. The specific objectives of this research program were: (1) to evaluate the flight instructors' ability to predict success in private pilot training on the basis of students' initial performances in each of two ground trainers as opposed to actual aircraft, (2) to determine the relative value of 11 hours of flight instruction in two different ground trainers, and (3) to develop an objective scale for checking flight proficiency. There was a significant positive correlation of 0.50 between predictions based on two hours of training in the ground-based trainers and actual hours required to pass the flight check, but a nonsignificant negative correlation of 0.22 for predictions based on two hours in the aircraft. The ground trainer groups passed their flight checks with an average of slightly more than an how greater total time than those trained exclusively in the aircraft. On the basis of equivalent levels of group performance, 11 hours of training in the AN-T-18 resulted in a saving of 9 hours of flight time, thereby yielding a transfer effectiveness ratio of 0.8. Eleven hours of training in the GAT-1 resulted in a saving of 11 hours of flight time, yielding a transfer effectiveness ratio value of 1.0. The transfer effectiveness ratio is a new measure that directly relates the saving in learning one task to the amount of training on another.

The XF3-30 engine has been successfully completed its Qualification Test at March 1986 and the production has started as the powerplant for Japan Self Defence Force’s intermedeate trainer T-4. The first flight of the T-4 powered by two XF3-30 engine was made on the 29th July 1985. More than 500 test flights have been made in these two years and engine flight time has accumulated to over 1,500 hours. This XF3-30 engine has been imposed strict requirements of the structural integrity to meet the MIL-E-5007D specification. This paper describes the structural features of this engine and some structural problems encountered through the development. The improvements for these development problems are covered.
