Ground effect includes a reduction of induced drag, increase of lift, and nose-down moment during landing. These phenomena, occurring late in the landing maneuver, are considered to be of little significance because they tend to counteract and/or compensate in this respect. Even though it is unlikely to affect any flare profile variations appreciably, some pilots have reversed perception about such phenomenon and overestimate during landing. It is becoming a negative factor and is making an adverse effect on landing maneuver. This study examines the perception of ground effect of large aircraft pilots, reviews literature regarding ground effect, and makes suggestions that pilots can correctly recognize and respond to the effect during landing flare maneuvers.

This paper tried to analyze the response of air traffic controller(ATC) against abnormal situations using survey based on cognitive strategies suggested by Malakis et al.(2010). The survey designed to empirically analyze the effect of the cognitive strategy factors on organizational effectiveness. The main purpose of this research was as follows: First, it was analyzed both the individual-scale and team-scale factors which constructed the cognitive strategy against abnormal situations. Secondly, how seriously impact the ATC's cognitive strategies on their organizational effectiveness. The organizational effectiveness was divided into such two latent variables as job absorption and job satisfaction. According to the a analysis, it was proven that premeditated act of ATC had a positive significant effect on team-scale cognitive strategies such as teamwork, communication and error management. Moreover, it was found out the team-scale cognitive strategies had also a positive significant effect on job absorption. On the other hands, individual-scale cognitive strategies had no or negative effect on job absorption. Job absorption was proven to have a significant effect on job satisfaction of ATC.

This paper presents a new airport slot allocation model that uses AIP model to balance the use of airport slots within existing capacity based on the limitation of capacity expansion of airport slots. This new model is called a 'balanced airport slot allocation model', which integrates the airport facility usage system, which is applied independently without linkage, with the airport slot allocation system, introducing the market logical characteristic of 'administered incentive pricing. In this paper, we propose a new proposal to dramatically change the airport slot allocation system in the current situation where the expansion of facilities is limited in the urgent problem of the airport slot shortage, and it is necessary to balance the airport slot allocation. Airline paying for the use of an airport slot can determine the slot of the desired time slot based on the costs incurred by differentiating in the new airport slot allocation model. This is a system that allows the airlines that are willing to pay a lot of money in the market to use preferred airport slots.

There has been the migration to a performance-based approach in many areas which include transition planning at global, regional and local levels, performance-based navigation and safety management. Achieving continuous success of Air Traffic Management (ATM) systems would require a performance-based approach to raise productivity and efficiency of it through performance measurements and reviews. This paper considers establishment planning of performance measurement and evaluation system for ATM. Related to key performance areas proposed by International Civil Aviation Organization, performance indicators and metrics which could be used to measure and evaluate ATM performance are presented. Also, organizational system and operational planning for efficient operation of ATM are presented.

2003년 ICAO가 국제 조종사에 관한 언어능력 기준을 제시한 이래로 국제노선에 취항하는 한국 항공 종사자들은 영어 능력을 증명하기 위한 노력을 해왔다. 1969년 처음으로 항공영어교육이 시작되고 2006년 처음 시험이 도입되면서 한국은 이를 충족하기 위한 알맞은 영어 교육 프로그램을 시행하려 시도해 왔다. 그러나, 항공영어 교육과 시험에 관련된 문제점들이 꾸준히 제기되었고 특히 항공 종사자들의 필요와 요구에 맞지 않는 시험 제도와 내용에 대한 논쟁이 끊이지 않았다. 본 연구는 이러한 측면에서 항공영어와 교육에 대한 이론적 접근과 더불어, 106명의 항공종사자에게 실시한 설문지를 토대로 그들의 항공영어와 일반영어에 관한 의견, 항공영어시험에 관한 의견을 수집 분석하였다. 조사결과, 참여자들은 현재 실시되고 있는 항공영어시험이 실제 업무를 효과적으로 반영하지 않으며, 좀 더 실제적인 내용이 시험에 반영되기를 희망하였다. 즉, 항공영어 시험이 좀 더 업무에 사용되는 영어를 많이 반영하고 난이도를 고려한 새로운 형태의 시험이 개발 되어야 한다는 의견이 많았다. 또한, 설문지를 통하여 나타난 여러 사항들을 바탕으로 향후 항공영어 평가가 나아갈 방향을 항공종사자의 측면과 관련 교육기관과 시험출제자, 관련 당국 등 3 가지 분야로 나누어 논의 하였다.
