the owner of the aircraft or the enterprise which benefits from its use or operation may have civil liability for injuries to persons or property on the land or water or in the sky. regarding this liability many questions can be raised: who is the responsible person and what are the harmful acts and damages which can be resulted from using aircraft and how can harmonize the property rights of p...

Thanks to the digital revolution, digital signal processing and control has been widely used in many areas of science and engineering today. It provides practical and powerful tools to model, simulate, analyze, design, measure, and control complex and dynamic systems such as robots and aircrafts. Gene networks are also complex dynamic systems which can be studied via digital signal processing a...

This work illustrates how to calculate accurate aircraft maintenance costs using Activity Based Costing (ABC). Comparing to traditional cost calculation, the proposed method is useful for aircrafts maintenance activity integrated to Airline Company and who wants to diversify its revenue by selling some available maintenance slots to third party clients for a competitive price. This paper takes ...

In propeller driven aircraft the main source for internal noise are almost tonal disturbances caused by the propeller blades that are passing the fuselage. In a certain four propeller military transport aircraft the maximum sound level in the cabin can reach up to 110 dB(A), not taking into account any noise control treatments. Inside the semi closed loadmaster working station (LMWS) the sound ...

BACKGROUND The Human Factors Analysis and Classification System (HFACS) is a general human error framework originally developed and tested within the U.S. military as a tool for investigating and analyzing the human causes of aviation accidents. Based on Reason's (1990) model of latent and active failures, HFACS addresses human error at all levels of the system, including the condition of aircr...

The development of aviation engine control soft ware is a prime example of a process in which the overriding concern is safety In building such a com plex system change is inevitable This paper discusses the aims of CONVERSE an EPSRC funded project to investigate change management in safety critical soft ware development The aim is to reduce the costs which occur due to change while allowing ra...

The number of fatal accidents involving public transport aircraft has increased significantly in recent years and, because more and more "wide-bodied" aircraft have been coming into service, this has resulted in a rapid increase in the number of fatalities. A combined attack on the problem by all concerned with flight safety is required to improve the situation. The collection and analysis of a...
