be under the control of that State. A detailed list of the top 50 most constraining points in
Europe can be found in Annex VI.
16 It should be noted that, in many cases, the shortest route even if not planned is already given on a tactical basis by
Air Traffic Control. Improvements in “route utilisation” could reduce potential improvements in “ATC Routing”.

5.4.3 Particularly with a view to the setting of binding performance targets within the SES
performance scheme it is important to note that the use of national flight efficiency targets
is influenced by the dependency of the route structure on adjacent States. It furthermore
highlights the importance of the development of a Pan-European network improvement
plan in collaboration with States/FABs.

5.5 Access to and use of shared airspace
5.5.1 Access is one of the ICAO key performance areas. This
section focuses on access to shared airspace by military
and civil users.
5.5.2 In order to meet the increasing needs of both
stakeholders in terms of volume and time, a close
civil/military co-operation and co-ordination across all
ATM-related activities is key to maximising the use of
scarce airspace.
Shared airspace
“Shared” is AMC17 manageable
Special Use Airspace (SUA) that
consists of individual airspace
volumes and opening times and can
be used alternatively for civil traffic
and military activities. It is no longer
designated as either military or civil
airspace, but considered as one
continuum and used flexibly on a
day-to-day basis.
5.5.3 From a civil point of view, the benefit of access to shared airspace is improved en-route
flight efficiency (see previous section). From a military viewpoint, access to shared
airspace enables military training programmes. The shared airspace should be located in
proximity to airbases in order to optimise transit times to the training areas.
5.5.4 The PRC report “Evaluation of Civil/Military airspace utilisation” in 2007 [Ref. 20]
raised two main points:
for States to increase their commitment to design and implement appropriate routes
and sector configurations to improve the utilisation of shared airspace particularly
during weekends, and
to establish a performance measurement system for the utilisation shared airspace.

5.5.5 In order to facilitate civil/military coordination and to support a more consistent crossborder
implementation of the flexible use of airspace (FUA) planning process,
EUROCONTROL has launched a number of initiatives such as LARA18, CIMACT19 and
PRISMIL.20
5.5.6 Of particular relevance is the need to ensure that airspace is used when made available
particularly when the shared airspace is temporarily segregated either for military or civil
airspace users.
5.5.7 Although there is virtually no
military activity during
weekends, only a small
reduction of direct route
extension can be observed, as
shown in Figure 71.
5.5.8 Although a gradual
improvement of direct route
extension is visible between
2004 and 2009, the gap
between week and weekend
remains stable.
