the publication of their safety data to simple tables depicting the number of incidents and
accidents per year or per flight hour. The level of transparency in the sharing of safety
information is, in principle, closely related to the level of implementation of Just Culture
in the particular State.
3.8.2 Publishing general safety information is however not uncommon in Europe. Figure 35
shows that safety information is published in many States, whether by the ANSP, the
ANS regulator or both. Some of them have not made publicly available any safety
information, while a growing number of ANSPs have published, in their annual reports,
indicators on risk-bearing incidents as well as safety objectives in some cases. A sample
of that data can be found in the ANSP fact sheets in Annex X of this report.

3.9 Automatic Safety Data Acquisition
3.9.1 Within the Performance Scheme of the SES II legislation, safety is explicitly identified as
one of the key performance areas to be monitored. Furthermore, with increasing pressures
on the other three areas (i.e. capacity, environment and costs), safety needs to be very
closely monitored to ensure that pressure from other performance areas does not
negatively impact safety.
3.9.2 The PRC has long advocated
the general introduction of
automated tools for assessing
safety performance.
Currently, there are a number
of such initiatives backed by
various solutions.
3.9.3 It appears that acceptance of
automatic acquisition data for
the purposes of safety and/or
risk monitoring has made
great progress lately, in
particular in the context of
ensuring safety under the
pressures from other areas
highlighted above.

3.9.4 Automated data acquisition tools already exist in a number of ATC centres. More stations
are to come.
3.9.5 Automated safety data acquisition can serve two different but complementary purposes:
First, automated safety data acquisition can be used by the ANSP to augment the
manual data collection in support of its own Safety Management System (SMS),
PRR 2009 Chapter 3: Safety
27
where events detected manually or automatically are analysed and lessons learned are
used for a continuous improvement of the safety level.
The other use of automated safety data acquisition is done rather at a Local or
European scale for the purpose of monitoring a certain level of risk. The focus of
such monitoring is not the individual event, but aggregated statistics that are not
influenced by change of the level of safety occurrence reporting. Such statistics can
provide indication of trends in time, or identify geographical ‘hot-spots’ or highlight
other sensitive issues.
3.9.6 The establishment of automated data acquisition tools at European level is not a
technological issue. It requires however a clear mandate and right of access to data to
develop an independent means for safety risk measurement: (i) to support the monitoring
of airspace infringements, ground proximity, separation minima infringements and level
busts and (ii) to enable these occurrences to be mitigated at European level.
3.9.7 A good example of such approach is the height monitoring unit (HMU) which has been
established related to a particular operational issue (i.e. RVSM). One of the roles of the
HMU is to assess the risk of collision in the vertical plan and to monitor that the Target
Level of Safety (TLS) is being met.
3.9.8 Moreover, EASA regulations for the automatic collection and investigation of TCASderived
encounters offer the prospect of developing an automatic safety data acquisition
tool for European ATM.
3.9.9 Additionally, systematic capture and analysis of safety occurrences in the European
network (hotspots) are essential for the Network Management function in their role of
