One major safety issue of surface operations is the occurrence of runway incursions. Runway incursions are the consequence of multiple operational and/or environmental factors. Human error is known to contribute to almost every runway incursion. One major contributing factor for runway incursion is crew's lack of situational awareness during airport surface operations, induced by weather considerations, by complex airport factors or by crew technique itself; it is also caused by ATC issues. Various airport factors may affect pilot situational awareness, distract the crew, or lead to crew confusion. The recommendations to avoid runway incursions are manifold; Proper Crew's CRM/TEM skills, adequate communication technique, proper knowledge of airport surface markings, lights and signs and preparation of preparation of expected taxi out/in routing. Also runway incursion risk assessment on specific airport before flight may lead to aware of risk level and contribute to prevent runway incursion.

The AHP methodology compares criteria, or alternatives with respect to a criterion, in a natural, pairwise mode. AHP has been applied in a wide variety of applications multi objective decision making being just one. If a group of expert with different aspect, they need some way to revise expert group. We proposed the concatenation of expert to survey the AHP pairwise question for multi-attribute decision making. In this paper, we suggest a way to revise the expert's priorities in hierarch using concept of different group opinion.

비행 편수의 증가 추세는 관제 밀집도를 높여 항공관제 사와 조종사간 communication 실수를 유발할 수 있는데 특히 호출 부호(Call Sign)의 혼동, 착각에 의한 경우가 많은 것으로 나타나고 있다. 항공 관제사와 조종사간의 communication 실수는 항공기 고도 위반, 활주로 침범, CFIT, 공중 충돌, Near Miss로 인한 위험 상황을 초래할 수 있다. 본 연구는 민간 항공사에 근무하는 조종사들의 유사 콜사인에 대한 혼동 정도와 위험성 인식을 설문 조사하였으며 이를 분석하여 방지 대책을 모색하였다. 국내 조종사와 외국인 조종사의 혼동 정도와 위험성 인식의 차이는 나타나지 않았으며 공항이 위치한 국가에 따라 혼동 정도의 차이가 있었다. 동일 항공사에서 나타나는 유사 콜사인은 자체 해결 가능하였지만 타 항공사와의 유사 콜사인을 해결하는 데는 한계가 있어 관계 기관의 적극적인 중재가 요구된다.
