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.

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.

The functionality of satellite navigation system on a flight with acrobatic elements: Ground and flight testing

This paper deals with functionality verification of satellite navigation system GPS-150 before its application for air traffic. The goal of this project was to verify GPS-150 properties with regard to its fundamental functionality — provision of navigation information during flight. Within the research, the main focused was placed on GPS-150 operation during specific flight conditions with acrobatic elements. Another goal of the project was to obtain complementary operational information, which were not included in users handbook. For this purpose, ground-based verification methodologies were developed. The project was concluded by flight tests.

Telemetry System Utilization for Stress Monitoring of Pilots During Training

Air transport development brings an increased focus on the safety of piloting. The safety conditions can be assessed by mental workload. Psychic discomfort or excessive stress on pilots can negatively influence the course of flights. Therefore it appears convenient to monitor such parameters, which represent the mental wellbeing, or discomfort of a pilot. Since physiological measurements can provide a good information about mental workload or stress, this work primarily focuses on the observation of the change in heart rate, as it is an indicator of stress during the training of pilots, using the designed modular telemetry system. Another aim of this study is to evaluate the influence of a change in the avionic data visualization. This can have an unfavorable effect on the piloting of an airplane. This work, based on the evaluation of heart rate shows, that the switch from analog visualization to glass cockpit creates increased levels of stress in pilots, which was proved for all examined subjects except one. Significant level of correlation in the heart beat rate change in subjects in the course of training was also discovered.

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.

State Safety Programme and State Safety Plan - Part one – State Safety Programme structure

State Safety Programme and plan are considered the main instruments in safety management. In that matter, this paper focuses on their description and simultaneously tries to clarify a need and significance of their establishment and implementation within respective state. All elements, defined in ICAO doc. 9859 as State Safety Programme (SSP) fundamentals, are separately described. These elements are divided into four groups, further detailed in individual chapters – State Safety Policy and objectives, State Safety Risk management, State safety assurance, State Safety Promotion.
