ABSTRACT
The purpose of this study was is leading landmark efforts to prevent the major causes of commercial-aviation fatalities about controlled flight into terrain (CFIT) in approach-and-landing accidents. The paper of major analysis for controlled flight into terrain (CFIT) was Guam accident, Mokpo accident and Gimhae accident in commercial transport-aircraft accidents from 1997 through 2002. CFIT occurs when an airworthy aircraft under the control of the flight crew is flown unintentionally into terrain, obstacles or water, usually with no prior awareness by the crew. This type of accident can occur during most phases of flight, but CFIT is more common during the approach-and-landing phase. The paper believed that prevention for CFIT accident was education and training for flying crew and upgrade for equipment such as EGPWS, and need more research for professional organizations of airlines.
