This Paper presents an analysis of test data recorded during flight trials of a gyroplane. This class of rotarywing aircraft has found limited application in areas other than sport or recreational flying. However, the accident rate is such that a study of the configuration's stability and control characteristics is timely, and in addition substantive data is required for a new airworthiness and...

In April 2006, an Unmanned Aerial Vehicle crashed near Nogales, Arizona. This incident is of interest because it triggered one of the most sustained studies into the causes of failure involving such a vehicle. The National Transportation Safety Board together with the US Customs and Border Protection agency under the Department of Homeland Security worked to identify lessons learned from this m...

This study analyzed Remotely Piloted Aircraft System (RPAS) deployment in the Regional Services of Aeronautical Accidents Investigation and Prevention (SERIPA – Brazil) as a support tool to investigate aviation accidents. Such review is justified by acquisition use this equipment new technology investigators since 2017. Research aim was analyze perception SERIPA regarding usefulness ease RPAS e...

Loss-of-control is a major contributor to aircraft fatalities. Recent work has been done to develop quantitative criteria for determining loss-of-control from accident time history data. This work proposes an approach to estimating boundaries on control actions to provide information to pilots and/or control systems to assist in avoiding loss-of-control scenarios. Data-based predictive control ...

Toxicological evaluation of postmortem samples collected from a pilot involved in a unique fatal civil aircraft accident is described in this paper. A one-occupant airplane was substantially damaged upon colliding with terrain in poor visibility. Remains of the pilot were found outside the aircraft. Pathological examination revealed multiple blunt force injuries and vascular congestion. The flu...

When the editor suggested that we write a piece for this 50 edition of the newsletter, it seemed appropriate to reflect on the longer term history of our field and, in particular, to focus on the topic of accident investigation which has been the focus of our previous work. In early 1928, the Assistant Secretaries for Aeronautics in the Departments of War, Navy, and Commerce in the United State...

This case study is a human factors analysis of the aircraft collisionwhich occurred at the LosRodeos airport in Tenerife, on the Canary Islands. The collision between two 747 jumbo jets cost the lives of 583 people. This collision is an example of how large scale disasters result from errorsmade by people in crucial circumstances and illustrates the potentially devastating consequences of ineff...

An analysis was conducted to examine the market visibility of small aircraft as a transportation mode in competition with automobile and scheduled commercial air travel by estimating the pool of users that would potentially switch on-demand air travel due to cost/time saving. These new aircraft greatly increase the practicality of regional aircraft as a transportation mode that can avoid the co...

A total of 86 fatal light aircraft accidents in the United Kingdom from January 1964 to December 1973 are reviewed, in which tissue alcohol determinations were undertaken on 102 pilots. Alcohol was detected in 34 cases varying from small amounts of 313 mg/100 ml. The difficulties of interpretation of post mortem tissue alcohol levels are discussed with particular reference to those cases with m...

The lack of robustness in current diagnostic systems is an important research issue because it has two major consequences: inability to diagnose novel faults and inability to diagnose more than one type of fault. This paper describes an approach that formulates diagnosis of physical systems in operation (operative diagnosis) as problem solving in a hypothesis space. Such a formulation increases...
