The purpose of this study is to develop questionnaire items for the Pilot Aptitude Personality Test(PAPT) which can predict the flight training achievement through personality and personal characteristics. To do this, we investigated the personality traits required to successfully conduct flight training for 30 flight instructors as a subject. The results were as follows: motivation, concentration, concentration, situational awareness, and concentration. Based on this, preliminary 300-item questionnaire was prepared by combining the existing studies related to pilot aptitude. Survey was conducted using preliminary questionnaire for 152 student pilots as a subject. As a result of the correlation analysis between the results of the questionnaire and the flight training, 16 questions were derived. Finally, factor analysis showed that the final 14 questionnaire items were confirmed. The internal concept of an item is categorized as personality, perception, and motivation. This study suggests that the pilot aptitude should be viewed from an extended point of view by analyzing individual characteristics and pilot aptitude in relation to flight training achievement.

The purpose of this study was to analyze the face validity of the revised EPTA (English Proficiency Test for Aviation) to see if the tests actually contribute to the enhancement of aviation safety and achieve the purpose of the assessment. In order to reach the above objectives, 103 pilot test takers were surveyed, and nine in-depth interviewees were selected and interviewed. In addition, detailed research results were derived by dividing the participants into the pilot's flight experience (31 captain pilots, 42 first officer pilots, and 30 general commercial pilots). As a result, pilot participants were generally aware that EPTA was more reasonable because the revised EPTA properly implemented the aviation situation and gave participants motivation to learn aviation English. It was also seen that first officer pilots had a higher face validity of EPTA than captain and general commercial pilots. The reason was that first officer pilots considered air traffic control job was more important than other pilots did.

Korea Gas Corporation has recently constructed a LNG pilot tank with 1, 000㎥ capacity in Incheon, Korea. The main objective of this pilot tank construction is to accumulate field data under different operating conditions for the future use in design procedure, construction, and maintenance. As the part of the project, a field dynamic test, so-called modal test, is performed to obtain the dynamic characteristics of the pilot tank. This paper describes the instrumentation and measurement Process used in the testing. From the measured Frequency Response Functions (FRFs), resonant frequencies and corresponding mode shapes of the tank are extracted and provided. Also, these results are compared to those calculated from a finite element model. The change of dynamic characteristics of the pilot tank due to the effect of internal fluid and the possible structural deterioration will be investigated in near future.

The objective of this paper is to develop an evaluation model for pilot informatization projects. There are relatively many researches on evaluation models for information systems. These previous researches, however, lack of comprehensive view of informatization Projects and pilot systems. We apply and test a hybrid evaluation model for to measure the success of pilot informatization projects. A user satisfaction model has been used and hypotheses are developed to find relationships of evaluation factors. The hypotheses have been tested with 51 user surveys. The result of this research can give an insight for the evaluation of pilot informatization projects.

Through the use of well-designed measures of ability and aptitude, good selection can reduce training wastage, reduce the risk of accidents and increase the operational effectiveness of the successful trainees. Many countries in the world, they take various kind of aptitude test. Especially in Sweden, not like the other countries, they attach importance to interview test. As a result, they can reduce training wastage and accidents. In case of ROKAF, they take many kind of aptitude test, but it is not directly effective to the selection system. They take the several aptitude test in civil aviation in Korea, especially they attach importance to personality test. For the validity and accuracy of the aptitude test, until training pilot become professional pilot, we need a comparison analysis for initial aptitude test through the continuous observation. For theses process, we need a department with special person and development of testing system.

Axial vibration analysis is very important for a deep-seabed mining system. In this study, an axial vibration analysis was carried out to estimate the natural frequencies and tensions of the umbilical cable using experimental data obtained from the first pre-pilot mining test. The axial vibrations of the umbilical cable with a pilot mining robot at the bottom end were analytically determined. The range of the added mass coefficients of the pilot mining robot is estimated by comparing the experimental and analytical data. The natural frequencies and maximum tensions are calculated using four estimated added mass coefficients.

Recently, the need of RPA(Remotely Piloted Aircraft) pilots is increasing rapidly with many requirements in order to be a beginner RPA pilot, including basic flight training, instrument flight qualification training, and aircraft type switching training. When RPA pilot gets disqualified, there will be generated much waste of efforts and expenses of trainees those pilots who are disqualified. Therefore, the methodology of pre-verifying those pilots who are not proper as RPA pilots through various scientific methods will save time and expenses with pre-reducing the pilots who will get disqualified later on. The methodology of aptitude test of RPA pilots is laid out as a consideration of pre-study of RPA pilots work analysis, and select types of aptitude test. A suitability of aptitude test is verified. In order to diagnose the flight aptitude precisely, it requires to be developed. Flight aptitude test tools might be connected with training program which could foster piloting aptitude with pre-diagnosing RPA pilot trainee selecting process. For that reason, we made an experiment in order to verify credibility and suitability of these selected programs with developing RPA pilot aptitude test tools. And also, we analyzed relationships among characteristics, analysis of data, and variables to verify the efficiency of data from prior experiment. Through this thesis, we expect to raise efficiency of flight training by providing pre-flight aptitude test information of RPA pilots.

The main purpose of this paper is cost reduction in absurd pilot positive expense and human accident prevention which is caused by in the pilot selection process. We use classification models such as logistic regression, decision tree, and neural network based on aptitude test results of 505 ROK Air Force applicants in 2001~2004. First, we determine the reliability and propriety against the aptitude test system which has been improved. Based on this conference flight simulator test item was compared to the new aptitude test item in order to make additional yes or no decision from different models in terms of classification accuracy, ROC and Response Threshold side. Decision tree was selected as the most efficient for each sequential flight training result and the last flight training results predict excellent. Therefore, we propose that the standard of pilot selection be adopted by the decision tree and it presents in the aptitude test item which is new a conference flight simulator test.

It is important to select the personnel with ideal pilot aptitude considering dramatically advancing aircraft performance and complexity of military operations as a consequence to the highly developed science and technology. The opportunity cost lost from dropouts and human error being the first cause of aviation accidents are the realistic reasons for the significance of personnel selection based on their aptitude. This study analyses the ROKAF pilot aptitude test that was improved in 2004, using various classification models. This study discusses the significance of the selected variables along with the direction of ROKAF pilot aptitude test for its development in the future. The accuracy of the classification models was improved by taking into account differing personnel characteristics of individuals on the test.

In this study, we tested hybrid pilot system combined with soil vapor extraction and bioventing methods on the contaminated railroad soil. So, we found out the remediability and operating conditions. Air permeability(k) and gas phase(O$_2$/CO$_2$/VOCs) level trend are very important to determine the remediation rate of the contaminated sites. Throughout hybrid pilot test on different conditions, the range of air permeability(k) was 1985∼1194 darcy. The tests results in hybrid system was appropriate on this test sites, and the suitable injection air flow rate was 3.5㎥/hr. So, we suggested a basic data for the remediation and management of contaminated railroad soil.
