Challenges of Implementation and Practical Deployment of Aviation Safety Knowledge Management Software

This paper introduces practical issues of implementing and deploying safety knowledge management software to aviation safety. Domain specific intangible nature of the issues concerned is described and all factors which prevent successful application of any knowledge management system are documented. Aviation organizations are struggling to find any effective solution which would on one hand allow timely tracking of the dynamic knowledge and on the other to not limit or bias reporters or investigators within the knowledge gathering process. The article deals mainly with practical issues concerning the deployment of reporting software, which constitutes the interface between humans and ontology model behind the software, capable to address trade-offs between various conflicting design criteria as well as many aviation organization types, as the aviation safety knowledge is to be gathered in cooperation with the industry.

Determining importance of physiological parameters and methods of their evaluation for classification of pilots psychophysiological condition

At present, several studies exist describing the relevance of human factor in air transport with main focus on pilots and flight safety. Within such studies, monitoring of physiological functions is used. There are lot of physiological parameters and methods of their assessment; however, they are mostly based on principles originating from clinical practice. Yet, sensitivity and specificity of these methods with regard to assessment of aviation professionals — pilots is unknown. Therefore, this paper is oriented towards description of the most common methods for physiological parameters assessment. The paper also describes evaluation methods, which are on experimental level in terms of physiological data evaluation, namely recurrent quantification analysis. Within the research carried out, sample group of pilots was subjected to measurement for evaluation of their psychophysiological condition and performance. Selected evaluation methods were applied on the collected data and importance of those parameters and methods, which provided best classification for level of psychophysiological stress, was evaluated by means of statistical analyses. The results indicate that the most important physiological parameter for psychophysiological condition assessment of pilots is heart electrical activity where the possibility to perform signal processing whilst preserving its importance is provided by linear methods in the time and frequency domain, or alternatively by non-linear methods utilizing recurrent quantification analysis.

The Methodology for Evaluating the Safety of Operations at the Uncontrolled Aerodromes

The objective of this methodology is to determine the general procedure for the evaluation of safety indicators for operation at uncontrolled aerodromes. The basis of this assessment is to determine the processes that take place at the aerodrome and finding critical points in these processes. They are determined on the basis of observations at aerodromes and are based on current legislation. The result of applying this methodology to aerodrome operations is the identification of several indicators, which monitoring and the adoption of safety measures can enhance safety at these uncontrolled aerodromes in the Czech Republic.

Predicting safety performance to control risk in military systems

This paper deals with research of safety performance predictions to allow improved risk control in military. Safety performance is identified as appropriate tool to establish system-wide information on safety which can serve the decision making process on how to manage safety. The information contributes to better understanding of behavioural patterns in the controlled system and the ability to foresee short-term future can provide key elements for justification of remedial measures. Aviation safety data served the research due to confidentiality restrictions in military. Data deficiencies were addressed by the means of developed simulator. Suitable mathematical models were identified and autoregressive model was selected and applied to predict computed safety performance. At the end, it was possible to validate the model. Remarks on its potential application into real military environment conclude this work.

Runway Safety Areas

This article is focused on areas around runway and their dimensions for safety reason of air accidents and incidents. There is proposed new calculation of these dimensions.

State Safety Programme and State Safety Plan - Part two – States’ approaches to the issue

The aim of this article is to bring a closer look on the various state approaches to the State Safety Programme (SSP) and plan implementation and realization. Therefore, article describes and compares French, the United Kingdom, Finland, Belgium and Ireland approaches. Besides that, it also focuses on the differences between the old and newly issued French safety plan. The article brings an overview of the specific risks, defined in the individual state safety plans, and their classification into particular categories

Safety KPIs - Monitoring of safety performance

This paper aims to provide brief overview of aviation safety development focusing on modern trends represented by implementation of Safety Key Performance Indicators. Even though aviation is perceived as safe means of transport, it is still struggling with its complexity given by long-term growth and robustness which it has reached today. Thus nowadays safety issues are much more complex and harder to handle than ever before. We are more and more concerned about organizational factors and control mechanisms which have potential to further increase level of aviation safety. Within this paper we will not only introduce the concept of Key Performance Indicators in area of aviation safety as an efficient control mechanism, but also analyse available legislation and documentation. Finally we will propose complex set of indicators which could be applied to Czech Air Navigation Service Provider.

Analysis of the process model of airport: creating the high level process map

This article describe the analysis of the process models of airport, which are described in Ground Operation Manual. The main goal is creating high level process map.

Reports about Occurrence of Events with Effect on Aviation Safety

T his article deals with a system, that is established to report the events with effect on safety. This system is based on requirements published in Annex 13 to the Chicago Convention and legislative foundations laid down in Regulation L13, Regulation of the European Parliament and of the Council (EU) No 376/2014, Decree No. 359/2006 Sb. and Act No. 49/1997 Sb. Standards and legislative rules precisely define the types of events that are subject of reporting and also define the structure and content of the reporting message. This content is consists mainly of the identification data about the airplane and crew, information about the route and a short description of the damage to the airplane. In the following, we discuss the possible use of such a system of mandatory reporting for the needs of safety indicators. Then there are proposals of changes in the content of the reporting message for the need of safety indicators. The present knowledge indicates that the use of all opportunities provided by the law for the reporting of events can lead to a creating of sufficient basis for safety indicators.
