The purpose of this study was to investigate the influence of air traffic controller's leadership characteristics and hazardous attitudes on the team effectiveness. The effectiveness make use of team efficacy and team commitment. Leadership characteristics and hazardous attitudes make use of the contents of a CRM manual. The study showed following results. 1) Leadership characteristics has a positive influence on the team effectiveness. 2) Hazardous attitudes has a partially bad influence on the team effectiveness. This study was conducted under the auspice of civil and military ATC facilies and by participation of devoting ATC controller's.

This study was conducted in search of the acceptance level of air traffic services from domestic airlines pilot's perspective in comparison with male controllers and female controllers. Pilots responded to the questionnaire that female ATC controllers are of significance to male controllers in terms of pronunciation, accuracy of English grammar, attitude and kindness. Besides, The ICAO aviation English proficiency level four test revealed that female controllers were found superior to male controllers in terms of rating scales of holistic descriptors.

This study was conducted with respect to the causal factors revealed through the investigation of the recent airlines aircraft crash accident which occurred while aircraft was on the climb-out or on the final approach. This study also highlighted the importance of flight deviation and exceedance occurrences in consideration of Flight Operational Quality Assurance Program(FOQA). Twenty airline pilots participated in the flight experiment to perform ten(10) sets of simulated approaches and landings. As a result, Twelve(12) kinds of deviation events were discovered. In this respect, The FOQA program must be fully implemented to prevent any flight safety incident under the auspices of the Korea domestic aviation community as well.

This study deals with the overall meta-cognitive aspects of ATC-Pilot miscommunications pertinent to cognitive human errors based on the previous literature research which it has been focused on the issue of the global aviation English use in regard with aircraft accident and incident. Especially, it addresses the concern over the ICAO aviation English language proficiency evaluation program which will be implemented globally in March, 2008. In addition, It presents the analysis related to the on-going English language proficiency level four test conducted for Korean civil airlines pilots and air traffic controllers.

According to Korea was re-elected as ICAO council member state at the 35th session of the assembly, there are more contributions and roles of international aviation society. Being developed technology and grown international transportation, world is focusing to aviation safety, Safety Management System(SMS) is systematic approach to manage risks caused by human and organizational factors. ICAO is specified that 'As of 24 November 2005, certified aerodrome shell have in operation a safety management system.' at Annex 14 to implement it airports as a first step. This study introduced SMS principle, analysed SMS's of advanced states and developed appropriate Korean Aerodrome SMS Model in our cultural and industrial circumstances.
