A Study on Human Error Risk Analysis of Helicopter Frequent Accidents through AHP Method

Helicopter pilots are required to perform many visual workloads in topographical avoidance, flight path modification and navigation, because helicopters operate at very low altitudes. The helicopter-specific instability also require the pilot have precise perception control. This has caused frequent human error helicopter accidents. In Korea, two three cases occurred annually on average over past 10 years, this trend not decreased. purpose of study was identify risks advance prevent accidents help develop measures for missions mission phases with high risk error. Through study, tasks where occur frequently were classified calculated each phases. To end, task during first identified, detailed steps classified, number analyzed. Next, AHP survey program developed measure
