Safety performance
Our priority is the safety of aircraft and the travelling
public. Our commitment to improving operational safety
performance is embedded in our RP2 plan which targets
a reduction in safety risk (defined as the accident risk per
flight) of 13% by 2020, in line with predicted traffic growth.
This year there was one category B Airprox 6 event
attributable to NATS (2014: one). The overall number
of Airprox events was 37 in 2015 (2014: 43), with four
attributable to NATS.
From January 2015, the SES performance scheme sets three
targets to be met by the end of RP2. These relate to the
effectiveness of safety management, the severity of safety
In 2011 we targeted a 10% reduction in the Weighted
events and the extent of Just Culture 7 training. Our plans are

5 The Weighted SSE Index is
a single figure calculated
by giving a weighted value
to our 4 event scores
(SSE 1-4). These values
are combined in the index
to provide the measure
of safety performance
used within the group to
track our overall safety
progress over time. It
distinguishes between
those events that are
attributed wholly or partly
to NATS, and those that
are not (although both
are addressed in our
safety activities). The
SSE scheme categorises
safety events based
upon severity (1-4) and
separation distance
(a-d), where 1a is the most
severe and 4d the least
severe.
6 An Airprox is a situation
in which, in the opinion of
a pilot or controller, the
distance between aircraft
as well as their relative
positions and speeds
have been such that
the safety of the aircraft
involved was or may have
been compromised. The
severity of these incidents
is assessed periodically by
the UK Airprox Board, an
independent body, in the
interests of enhancing
flight safety.
7 Training to promote an
atmosphere of trust
where front line staff feel
encouraged to provide
essential safety-related
information, and
with clear lines drawn
between acceptable and
unacceptable behaviour.
