Data from a national survey of pilots were used to examine the validity of measures for the prediction of aviation accidents that had occurred prior to the survey (retrospective analysis) and accidents that occurred after the survey (prospective analysis). Separate retrospective and prospective analyses were conducted, and 45 measures from the survey were found to be associated significantly wi...

The vertical stabilizer is a primary aerodynamic surface responsible for providing directional stability of an aircraft. Directional stability is further augmented by the yaw damping capability of the rudder using feedback control. When the rudder experiences faults or the vertical stabilizer is damaged, directional stability of an aircraft will be compromised. In the worst-case scenario, the v...

Much work has been carried out on using Petri Nets to describe interaction and the design of interactive systems. In this paper we are concerned with the use of Petri Nets to help describe accident scenarios. The issue here is that Petri Nets or some other formal notation might help eliminate ambiguities and imprecision that are characteristic of natural language descriptions in accident report...

The number of light aircraft (less than 5,700) in the developing world is small compared to those in the West, and little information on aviation accidents is readily available from developing countries. Papua New Guinea, enjoys a priviledged position, since aviation was introduced early and much of the country was opened through flying. During the period of Australian trusteeship until indepen...

INTRODUCTION Based on Reason's model of human error, the Human Factors Analysis and Classification System (HFACS) was developed as an analytical framework for the investigation of the role of human error in aviation accidents. However, there is little empirical work that formally describes numerically the relationship between the levels and components in the model (the organizational structures...
