2 Definitions
2.1 ‘Air traffic control clearance’ means authorisation for an aircraft to proceed
under conditions specified by an air traffic control unit.
2.2 ‘Approval’ means agreement in principle for a proposed action, subject to the
conditions of an air traffic control clearance.
2.3 ‘Controlled airspace’ is an airspace of defined dimensions within which air traffic
control service is provided in accordance with the airspace classification, namely
ICAO airspace classes A-E.
2.4 ‘Enhanced Non-Standard Flight’ (ENSF) is aerial task required to operate within
Restricted Areas EG R157, EG R158 and EG R159.
2.5 ‘Non-Standard Flight’ (NSF) in Controlled Airspace is an aerial task that may not
necessarily follow published routes or notified procedures; a formation flight of civil
aircraft other than for VFR transit of CTA/CTR/TMA; or flights to and from a
temporary landing site for multiple short term operations.

There would be no change in impact.
3.4 NATS does not plan to target airspace users classed as General Aviation (GA), such as parachuting,
ballooning/airships, helicopter operations and UAV/model aircraft flying.

The Board noted that allegations relating to drones had started to be logged in the
whistleblowing system since the end of 2018 (rather than being managed
separately).

Integrating versions of this into
navigation systems could ultimately enable
the detection of stealth or small objects, such
as drones, at greater distances, and it can play
a crucial role in counter‑unmanned aircraft
systems (counter-UAS) operations.

policies only:
I. an Airports National Policy Statement (NPS), for example, if the CAA
considers that a proposed airspace change could prevent the successful
delivery of on-going or future airspace changes that could increase future
capacity as agreed in that NPS;
II. maintaining UK national security, for example, a proposal that the CAA has
been advised by the Ministry of Defence or another government department
might have a national security impact on the operations of a site of critical
national infrastructure, such as a nuclear installation or prison;
III. the UK’s Industrial Strategy as it relates to space ports, but only where a
proposal establishes the airspace needed for operations from the first space
ports designed for sub-orbital use and vertical launchers, and which therefore
sets the precedent for future design and airspace change decisions;
IV. airspace zones specifically linked to the UK policy on the safe use of
drones

in the UK, but only in respect of the first proposal to establish
the airspace needed for the use of drones commercially (i.e. excluding
testing) and which therefore sets the precedent for future design and
airspace change decisions.
