Automatic Safety Monitoring Tool (ASMT)
From SKYbrary Wiki
The ASMT (Automatic Safety Monitoring Tool) is a tool for automatic gathering of ATM related safety occurrences in a defined airspace. ASMT monitors radar tracks, flight plans and safety nets data. When, according to criteria (parameters) that have been set in advance, a safety event occurs, data about the involved flights are recorded and stored in a database. The ASMT Human Machine Interface (HMI) can then be used to retrieve and replay the occurrence information, including flight plans and radar track data of involved aircraft. ASMT also offers a module for simple statistical analyses. However, data can be exported into formats that allow the use of third-party statistical tools, in case more advanced analysis should be needed. Data can be de-identified in order to keep identity of involved personnel undisclosed.
ASMT has been developed by the EUROCONTROL Experimental Centre and the first version was installed in MUAC (Maastricht Upper Area Control Centre) in 1999. Since then, several versions of the tool have been developed; at this moment, the latest released version is the 4.2.7. Nowadays several ANSPs throughout the whole of Europe are using ASMT for different purposes.
ASMT is a tool for the detection, storage and analysis of ATC events with a potential relevance for safety. For each detected event, ASMT records multiple data in a dedicated server, from which it is possible to extract and review them.
High-level objectives of use
The key reason for the introduction of ASMT is to monitor safety related indicators, in order to improve the current safety performance.
Possible uses of the ASMT include:
- Safety performance monitoring;
- Analysis of technical issues;
- Analysis of undesired events;
- Training support;
- Support to validation of operational concepts;
- ASMT output sharing.
Safety performance monitoring
In this case, the end goal is the identification of safety issues, in order to inform the definition of safety improvement actions. Detailed objectives may include:
- Analysis of events distribution;
- Trend analysis:
- Identify unexpected variations;
- Verify whether the safety targets have been achieved;
- Detail the target to be achieved regarding the objectives for the next period;
- Formulate an expectation for possible future directions of the safety objectives.
- Identification of hotspots;
- Validation of operational changes;
- Correlation analysis.
Analysis of technical issues
This class of objectives groups the objectives aimed at identifying technical issues at a systemic level in order to support the definition of technical improvement actions, including:
- Analysis of surveillance anomalies;
- Analysis of SNETs performance;
- Trend analysis;
- Identification of hotspots.
Analysis of undesired events
This objective aims at providing investigators additional opportunities to become aware of undesired events (e.g. marginal losses of separation that may go unnoticed, level busts etc.) and to facilitate the collection of data related to safety occurrences.
This class of objectives groups the use cases aimed at supporting training of ATC personnel. ASMT can be a useful tool to review events and support ATCO training, since patterns identified in single events can be used as examples of typical situations in which safety margins are compromised. Again, data shall be de-identified according to ASMT CONOPS provisions, at the level deemed the most appropriate to ensure that no attribution of blame shall be possible. It includes:
- Replay of occurrences suitable for training purposes;
- Support to risk awareness campaigns;
- Analysis of occurrences.
Support to validation of operational concepts
This class of ASMT usage groups the objectives aimed at supporting validation of new/changed operational concepts, e.g. in the context of real time simulations and includes:
- Collection of safety data in simulated environments;
- Collection of data about the performance of new or modified safety nets;
- Support to measurement of KPI in the validation process.
ASMT output sharing
These are the objectives aimed at sharing the results obtained by analysing the ASMT data. The basic principle is to share specific results and sets of data with organisations that are external to the ANSP, following the principles of Just Culture. This means that no attribution of blame shall be possible through the review of the data which, for this reason, shall be de-identified at the level that is deemed the most appropriate. It includes:
- ASMT output sharing with other ANSPs;
- Safety data promotion;
- Exchange of relevant safety information with stakeholders.
- Safety Performance Monitoring and Measurement
- Monitoring of ATM Safety Performance
- Safety Occurrence Reporting
- Flight Data Monitoring (FDM)
