The Role of Interdependence, Trust, Cooperation, and Relationship Effectiveness on Pilot and Air Traffic Controller Relationships
Choi, Y.C. ; Kim, C.Y. ; Kang, I.W. ;
Journal of the Korean Society for Aviation and Aeronautics, volume 9, issue 1, 2001, Pages 5~13
There are many studies which reveal most of the accidents are related to pilot errors. Looking at each phase of flight, the accidents which occurred at the segments of take-off and landing consist of 70%, cause these phases need precise cooperations between pilots and ATC specialists to make sure every instructions understood and instruments to be normal. Therefore, the accidents of these phases leave great regrets and the price was enormous to people and equipments. Until now, most of the studies investigate the accident itself and very few show the relationships between pilots and air traffic controllers. This study analyzes the impacts of inter-dependence to mutual trust, cooperations and relationship efficiency between them who play important parts in flight. Based upon the findings, the inter-dependence has an effect on mutual trust and the latter influences to cooperations. Also, mutual trust and cooperations have a leading role in the relationship efficiency. It implies that mutual trust, cooperations, and the degree of inter-dependence are important factors to improve the relationships between them.

The purpose of this study was to classify the cultural traits of Korean pilots who worked in two airlines in Korea. This study measured the typology of preferring value(horizontal-collectivism, horizontal-individualism, vertical-collectivism, vertical-individualism) with thirty two items developed by Triandis(1995), and analysis based on the target of 135 samples using SPSS 8.0. The result of this study shows that horizontal-collectivism were to predominant overall. It was also founding the captain had the collectivism oriented behavior, and the first officer had the individualism oriented behavior. Another finding of this study is that vertical oriented behavior were majority among the former military trained pilots, and horizontal oriented behavior were majority among the civilian trained pilots.
A Study on Standards for Establishing ATS Routes Defined by VOR in Korea

This paper addresses legislation status of air route design standard of Korea. Korea Ministry of Construction and Transportation's Order Number 300 (March 28, 2001) prescribes that firstly, the design of air routes in Korea should be in accord with International Civil Aviation Organization(ICAO)'s recommendations published in Annex 11: Air Traffic Service and Procedures for Air Navigation Services: Aircraft Operations (ICAO Doc 8168-OPS, 1986), and secondly, United States Federal Aviation Administration(FAA)'s Terminal Instrument Procedures (FAA, 1976). An investigation on the current air route specifications of Korea reveals that they are in accord with neither ICAO's recommendations nor FAA's standards in that the width of Korea's air routes are narrower that the international recommendations and standards. As a member state of ICAO, it is imperative for Korea to follow the international standards. In that purposes, Korea should legislate and regulate the detail standard for air route design. For the legislation, FAA regulations are to be followed because FAA rules contains more detail specifications while ICAO recommendations includes allows a range of policy decisions, which may result in a confusion in practice.
Airport Performance Measurement and Airport Operation System Improvement

According to the liberalization of the air transport industry, the operation of airport also takes account of economic efficiency. The owners or the operators of an airport or airport systems want to know what is the best way to achieve the best performance in the aspect of economic efficiency and they are willing to improve the airport operation system. Prerequisite for the improvement of economic efficiency is to measure the performance of not only their own airports but the other airports. This study presents the result of performance measurement of Korean airports. The overall costs performance, labor productivity, capital productivity, revenue performance and profit performance are estimated and interpreted. As conclusions, the suggestion about airport system improvement is presented.
Aeromechanical stability analysis and control of helicopter rotor blades

The rotor blade is modeled using a composite box beam with arbitrary wall. The active constrained damping layers are bonded to the upper and lower surfaces of the box beam to provide active and passive damping. A finite element model, based on a hybrid displacement theory, is used in the structural analysis. The theory is capable of accurately capturing the transverse shear effects in the composite primary structure, the viscoelastic and the piezoelectric layers within the ACLs. A reduced order model is derived based on the Hankel singular value. A linear quadratic Gaussian (LQG) controller is designed based on the reduced order model and the available measurement output. However, the LQG control system fails to stabilize the perturbed system although it shows good control performance at the nominal operating condition. To improve the robust stability of LQG controller, the loop transfer recovery (LTR) method is applied. Numerical results show that the proposed controller significantly improves rotor aeromechanical stability and suppresses rotor response over large variations in rotating speed by increasing lead-lag modal damping in the coupled rotor-body system.
