A Study on the exposure of electromagnetic waves in the B747-400 cockpit

Magnitudes of Magnetic field, Electronic field and Microwave was measured during the each stage of flight in the airline operation. The results was much higher than the safety standard and proved to be serious to the cockpit crews on their duty. We also identified that the magnitude of electronic field was much decreased by all three kinds of microwave protection equipments. We recommend that the cockpit crew have to wear the protection clothes to reduce the hazardous effects on their duty and the aircraft manufacturers have to consider the microwave-reduced cockpit in the initial stage of aircraft design.
A study on the policy proposals to enhance Aviation Safety in Korea
Lee, Kang-Seok ; Song, Byung-Heum ; Kang, Hoon ;
Journal of the Korean Society for Aviation and Aeronautics, volume 8, issue 1, 2000, Pages 23~47
Purpose of this paper is to enhance aviation safety in korea through comparison with aviation safety policies implemented by other countries. it can be another opportunity for Korean two national flag airlines to reappraise and reinforce the significance of "aviation safety", as well as set forth immediate vigorous efforts to support the government's aviation safety enhancement countermeasures. I hope this study would contribute and provide a variable idea and direction to enhance aviation safety management of two Korean flag carriers.

In the Aircraft Incident Reporting System(AIRS), It is important to collect and gather date about aircraft incidents by means of systemic methods and make it materials for study in the view point of aircraft accident in the future. Especially, the development of such effective tools can be one of main factors determining whether the investigation of potential accident factors succeeds or fails. For such a reason and the purpose of aircraft accident prevention, the AIRS compatible to each county has been developed early and been adopting now in several countries involving USA. First this study examine the actual condition about investigation method tools of potential accident factors used in several countries and investigation and analyze them, finally present the method which can improve more acceptable forms to flight crew used at the KAIRS(Korean AIRS).
Analysis of Air Traffic Delays at an Airpor

Benefit-cost analysis is one of key elements of feasibility study on a large scale investment for transportation infrastructure improvements. Benefit-cost analysis requires measuring expected benefits after the investment is completed. Reduction of delays is the major source for the benefit among other measurable benefits. Measurement methods for delays reduction have been reviewed and two methods were recommended for passenger delay and aircraft operation delay. Using these method, the effects of Cheju International Airport Improvement Projects were evaluated.
A study on the Aerodynamic Characteristics of a Multi-Functional Spoiler

An experimental study was performed on the time lag, lift and drag characteristics of a multi functional spoiler which is a device to increase lift and drag contrary to conventional spoiler which decrease lift and increase drag. In this study, a wind tunnel investigation was made of the effect of incidence angle, slot width, and chordwise location of multi functional spoiler on the time lag, lift and drag characteristics of a wing. The results indicate that the time lag of a multi functional spoiler is influenced mainly not only by the chordwise location of a spoiler but also by the slot width between spoiler and wing upper surface. Multi functional spoiler can reduce time lag effectively by slotting the trailing edge of spoiler with slot ratio (slot width devided by the wing chord length) between 0.05 and 0.1. Also, it shows that the lift and drag coefficients of the wing with the multi functional spoiler and trailing edge flap are increased by 20% and 80%, respectively, compared to the wing with trailing edge flap only.
Prediction of the Logitudinal Aerodynamic Coefficients of the Aircraft at Low Speed
Kang, Jung-Hoon ;
Journal of the Korean Society for Aviation and Aeronautics, volume 8, issue 1, 2000, Pages 83~95
Lift, drag, pitching moment, what we call longitudinal aerodynamic coefficient, effects airplanes directly, so the method to find the accurate result quickly is an important factor from the beginning of the aircraft design. There are different ways to find aerodynamic coefficient such as empirical methods, numerical analysis methods, wind tunnel tests, and finally through an actual flight tests, but choosing the best methods depends on the due date or the cost. The accuracy varies on each design level, but all this methods have relationship to complement and balance each other, so by combining proper methods, the best result can be obtained. At this paper, empirical methods and numerical analysis method were experimented, compared, and reviewed to find the availability of each method and by combining two methods accurate result was obtained. So, we applied this methods to predict the aerodynamic coefficient on cruise configuration aircraft, and was able to obtain more accurate result on the low speed longitudinal aerodynamic coefficient. Also by watching there result, we are able to predict the errors before the actual wind tunnel test.
Pilots' Understandings on the Pilot Education Curriculum and Teaching-Learning Methods

The analyses of the aircraft accidents across all of the world, including Korea, reported that 70 % of the accidents could be attributed to the faults of pilots' human factors. It implied that the aircraft accidents could be cut down remarkably if the pilots' faults were reduced. In this context, the purpose of the study were to explore and reduce the problems of authoritarian job performance in the cockpit operation of which mainly depended on the captain, though it was supposed that two or more pilots work together as a team. In relation to this, the current worldwide trend of pilot education had tended to emphasize education on the human factors of pilots since the strong recommendation of the International Civil Aviation Organization in the 1980's. From the educational dimension of the pilots, it was attempted to explore a new educational perspective which would enhance the flight crew's performance of the cockpit through improving the courses of the pilot education curriculum and the teaching-learning methods.
A Study of the interpretive rule on pilot's read-back error
Sin, Hyeon-Sam ;
Journal of the Korean Society for Aviation and Aeronautics, volume 8, issue 1, 2000, Pages 111~124
In this study, pilot's read-back errors were reviewed in terms of its cause and consequence while FAA tried to weigh a new initiative in the atc-pilot communication dispute in opposition of a majority of the aviation community by addressing an interpretive rule of 14CFR 91. Especially human factors in ATC communications were outlined with a view to suggest a line of recommendations for a successful accomplishment of safe flight in the busy terminal airspace.
