초록

조종사는 휴먼에러(human error)를 감소시키기 위한 방법들 중 하나로 체크리스트를 사용하여 항공의 안전에 도움이 되는 도구로 사용하고 있다. 하지만 복잡한 체크리스트는 경험이 부족한 학생 조종사들에게는 체크리스트가 작성된 본연의 목적과 다르게 안전에 위해 요인이 될 수 있다. 본 연구는 우선 학생조종사들이 사용하는 정상 체크리스트의 구성항목들을 단계 별로 살펴보았다. 이를 통해 체크리스트를 구성하는 요인들이 휴먼에러를 구성하는 요인들과 어떤 상관관계를 내포하는지 학생조종사들을 대상으로 한 사례연구를 통해 규명하고자 하였다. 탐색적 사례연구를 통해 다음과 같은 시사점을 제안하였다. 학생조종사들이 preflight inspection 체크리스트 점검을 수행함에 있어 기체에 대한 외부점검을 효율적으로 수행하도록 기체구조 또는 동력계통에 대한 전문지식 강화가 필요하다. 비행 시마다 조종사뿐만 아니라 해당 비행기의 정비 담당자가 외부점검을 실시하여 더블체크를 하는 재확인 절차를 통하여 안전을 증진시켜야 할 것이다.

Pilots have used checklist as a valuable tool to improve aviation safety and to reduce human error. A checklist however is too complex for a student pilot to use with less flight experience or time than a commercial pilot. It is agreed upon such complex checklist be a factor to threaten aviation safety for student pilots. This paper has focused on a checklist by dividing it into a couple of basic three flight procedures. Making exploratory case study of student pilots, researchers could analyze the correlation between checklist factors and those of human errors. First of all, it was necessary for student pilots to be educated professional knowledge regarding aircraft structures and engines to perform preflight inspection reducing human errors. Moreover it was recommended student pilots as well as maintenance crew confirm checklist together to enhance aviation safety.
