Brief description of the main ASL principles, policies and functions
Philosophy of ASL is defined by three basic principles:
Risks are subjective.
Safety is a subjective sensation which tends to changes and depends on the value system, experiences, circumstances and resources of airline. Therefore, for different airlines it is not possible to identify a uniform system of objective and permanent criteria of unsafe conditions.
*Risk management creates . . . additional risks. *
As the required accuracy of preventive actions is proportional to existing risks, a sequence of minimal actions will always be better than one set of global measures.
Improbable events have no statistics.
Effective prevention of serious consequences is possible only by prevention of relatively frequent events (medium risks). This requires the participation of all airline personnel.
Based on the above mentioned principles, the following policy was used for ASL development:
ASL shall provide a uniform approach to safety management as well as individual customization to address specific features of each airline.
To implement this approach, ASL shall establish and provide uniform types of objects and methods of safety management (ASL core), standard interface for entering and processing safety information (ASL shell), administrative interface for entering the wide range of airline individual data (airline customization level).
2. Ease of use (minimum redundancy).
ASL should not contain methods that have no practical value for airlines.
Simple, convenient and clear data format should not limit the completeness and depth of statistical and expert data.
ASL should provide data export to Excell.
3. The veracity of information.
Safety representatives shall be appointed in an airline divisions to analyze safety reports from staff and enter the identified causal relationships to the database (carrying out express investigation and analysis).
4. The completeness of the information.
ASL shall provide the airline Safety Manager with the forecasted probability of undesirable events as well as causal relationships and their impact on systemic weaknesses.
ASL shall provide the airline management with the opportunity of real-time search, grouping, sorting, and statistical processing of the airline safety data and information.
ASL shall provide an effective means for safety reporting for all airline employees.
5. Object of safety management.
The objects of safety management shall be restricted by systemic weaknesses in the airline, threatening the safety of flight operations at the level of medium risks.
Based on the above policies, ASL provides three types of safety management (Reactive, Proactive and Predictive) and supports the following functions:
- creation and maintaining the airline system of classifiers for adverse events in operation (airline intellectual property);
- safety reporting and storage of electronic reports from personnel in the form of classified information - adverse operational factors, preconditions, events, incidents, and direct operational consequences;
- search for information/reports and classified events in the airline electronic database;
- confidentiality and different levels of access to the electronic database;
- automatic generation of statistics by report types (mandatory, voluntary, confidential, anonymous) and by classified events at all levels of management (corporate and operational);
- selection and submission of information from a database according to the user's request;
- identification of typical relationships between negative factors, preconditions, events, incidents and direct consequences in operation of a specific airline;
- calculation of the actual monthly probabilities of operational events for the last two years (the average for the quarter);
- forecasting the probable operational events and automatic generation of safety warnings for predictive risk management;
- documenting the risk management actions, search and grouping of such actions to evaluate their effectiveness;
- calculating the weighted average of the total airline risk for the year.
