碩士 === 國立成功大學 === 民航研究所 === 95 === This thesis research collaborated with a domestic airline to investigate the flight data of 2,598 flights to Kimen Airport logged in the Flight Operation Quality Assurance data bank of the airline. The triggered non-standard events were studied and used to precede risk assessment. The statistical results showed that the risk level of Visual Approach on Runway 24 is higher than that of both ILS Approach and Visual Approach on Runway 06. The probability of triggering a standard “red event” of Visual Approach on Runway 24 is 4.12 folds of those selecting ILS Approach on Runway 06, while the probability of triggering a composite “red event” of Visual Approach on Runway 24 is 65.44 times higher than those selecting ILS Approach Procedure of Runway 06. The cause analysis indicated that the facts which make Visual Approach on Runway 24 riskier are composed by the factors of “terrain”, “psychological factor”, “operation skill”, “route of approach”, “ground navigation aids”, and “gross weight of aircraft.” The correlation analysis of Visual Approach on Runway 24 validated that the probability of triggering standard events such as “short flare”, “pitch high at touchdown”, “bounced landing” at touch down become higher when the flight had triggered composite events such as “continuously high during final”, “continuously steep during final”, “late offset in short final.” A scenario was made that late correction after triggered composite events during final would affect the accuracy of aircraft maneuvering and cause the potential risk of hard landing and runway overrun. Since Kimen Airport is difficult in nature (landform and weather), this study suggested that airlines should dispatch highly experienced flight crews in executing operations to Kimen Airport. In order to lower the risk of flights, the airlines should also put addition chapter of Kimen NDB/DME D Approach on Runway 24 in their Standard Operation Procedures, enhance wind-shear-encountered training, and try not to carry extra return leg tanked fuel. The conclusions also suggested that the authority should set up new navigation aids lamps or redesign the approach route of Visual Approach on Runway 24 in order to promote the progress of flight safety.
