Keywords: geometric matching, aircraft tracks, systematic errors of radars A problem of processing the measurements from air surveillance radars is considered. The measurements are provided by observation of air traffic. This processing aims at matching the tracks of aircrafts obtained by various radars and estimation of their systematic errors. The error estimates are built in the form of a " ...

In this study, general aviation accident records from the files of the National Transportation Safety Board (NTSB), have been analysed by gender to observe the number and rate of pilot-error related accidents from 1972 to 1981 inclusive. If both females and males have no difference in performance, then data would have indicated similarities of accident rates and types of injuries. Males had a h...

This paper is a 10-year review (2003-2012) of aircraft-assisted pilot suicides and is a follow up to our previous 1993-2002 review. From 2003-2012, there were 2,758 fatal aviation accidents; 8 were aircraft-assisted suicides (intentional crashing of aircraft). This is half of what we found in our previous 10-year review. All pilots involved in these suicides were male (median age 46, range 21-6...

Injury data were obtained from the U.S. Army Safety Center for the occupants of U.S. Army aircraft who were both wearing aviator helmets and involved in duty-related aircraft accidents, for the period beginning on 1 January 1972 and ending 1 January 1983. The injury data were correlated with the physical condition of the involved helmets, examined by the authors under an Aviation Life Support E...

The objective of the study was to compare the results of aviation accident analyses performed by the Center for Investigation and Prevention of Aviation Accidents (CENIPA) with the method Human Factors Analysis and Classification System (HFACS). The final reports of thirty-six general aviation accidents occurring between 2000 and 2005 in the State of São Paulo, Southeastern Brazil were analyzed...

Maintenance efficiency of complex industrial systems is an important economical and business issue. Main difficulties come from the choice of maintenance actions. A wrong choice can lead to maintenance costs that are not acceptable. In this paper, we propose a generic health monitoring system that integrates some diagnostic and prognostic capabilities to determine the current and future state o...

The patterns in this document combine observations, reinterpretations, rational reconstructions, and redesigns of Avionics Control Systems within the realm of the DSSA ADAGE project[3]. An Avionics Control System (ACS) is the main navigation system of an aircraft. An ACS continuously collects sensor data to estimate actual state of an aircraft, computes desired aircraft state with respect to gu...

In this paper, the problem of structural damage with partial loss vertical tail in aircraft dynamical system is investigated. A linearized aircraft model is introduced firstly, then a damage-tolerant controller based on an adaptive sliding mode control is proposed. Finally, simulations with an aircraft model are conducted to demonstrate the effectiveness and advantages of the proposed design te...

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...

Now-a-days there are several aircrafts have been lost due to some security issues. This paper overcomes the security issues by proposing a new ADS-B framework, in which it adds up some security. Using the airport authority the exact location, altitude and speed of the aircraft is monitored. In case of any hijacking of aircraft the base station authority can change the destination of aircraft an...
