CHAPTER 2: AVIATION AND RPAS
What are RPAS?
11. Until recently the majority of RPAS were
used either for recreational or military purposes. Small radio-controlled
model aircraft have been flown by enthusiasts in many countries
for decades. Today, the British Model Flying Association represents
over 820 affiliated clubs in the UK. As for military use, the
first recorded use of a remotely piloted aircraft was in 1935,
when the Royal Navy used the DH82 Queen Bee for target practice.
Over the last 10-15 years the United States military in particular
has developed more sophisticated RPAS for reconnaissance and operational
purposes. These military aircraft, such as the Global Hawk and
Predator, have commonly been referred to as 'drones'.
12. This inquiry has been concerned with the
more recent substantial growth in the civilian, and in particular
the commercial, use of RPAS, for example in aerial photography,
surveying and monitoring crops. We have not considered military
uses of this technology. We have, however, examined the growing
leisure use of RPAS.
Terminology
RPAS (SMALL AND LARGE), DRONES, AND
UAVS
13. Terms commonly used to describe RPAS include
drones, unmanned aerial vehicles (UAV), or unmanned aircraft systems
(UAS). The term UAV includes Remotely Piloted Aircraft Systems
(RPAS) as well as autonomous aircraft which can operate without
the intervention of a pilot. Many view the use of the term 'drone'
as inaccurate and misleading, as it fails to capture either their
purpose or degree of technological sophistication. AM-UAS Ltd
said that the use of the term 'drone' "unfortunately persists
in the civil sector and its military connotations bring a negative
association to many parts of the industry."[7]
14. For the purposes of this report, we have
decided to adopt the European Commission's preferred term, Remotely
Piloted Aircraft Systems (RPAS). As the term itself implies, RPAS
are controlled by a pilot, normally on the ground, who may directly
control or intervene in the management of the flight.
15. The basic components of an RPAS are the aircraft
which flies in the air, the pilot station (ground station), and
the command and control link (C2) connecting the two. The command
and control link is a radio data link between the pilot station
and the aircraft, which enables the pilot to give commands to,
and download data from, the aircraft along radio waves on a selected
frequency.
16. As the RPAS sector has evolved, the degree
of variation in each of these components has increased. RPAS include
very small, toy-like rotary aircraft weighing as little as a few
grams; fixed-wing aircraft which can be launched by hand or by
slingshot; and aircraft with a 40 metre wing span. The pilot could
be standing outside on open ground controlling the aircraft with
a handheld radio-control unit, or located inside a secure building
with a sophisticated control console using satellite connections
to communicate with the aircraft. The technology or materials
loaded onto the aircraft to enable it to collect data or complete
specific tasks, referred to as the payload, also vary depending
on the purpose of the operationexamples include cameras
and fertilisers.
COMMERCIAL, HOBBYIST AND LEISURE
USE
17. Our interpretation of civilian use of RPAS
includes use by commercial businesses for a profit, as well as
leisure use by private individuals. For private individuals, a
distinction can be drawn between 'hobbyists', who are traditionally
members of a flying club and have a good knowledge of aviation,
and the 'leisure user' who buys an RPAS off the shelf to fly in
a back garden or in a local park.
18. One of the issues encountered in our inquiry
has been the inconsistency of the regulatory framework, which
creates an artificial distinction between commercial and non-commercial
use of RPAS. The assumption that all non-commercial RPAS users
had a pre-existing knowledge of aviation no longer stands. Technological
developments have also resulted in similar aircraft being used
by commercial, hobbyist and leisure users, but under differing
regulations. The Civil Aviation Authority (CAA)said:
"Additionally, there is now a new 'leisure
use' emerging which should be noted. Due to the ever decreasing
size and cost of some systems as technology develops, small unmanned
aircraft are now being used by the general public as their 'personal
camera', offering new types of 'holiday snap'. This is a different
use from either the traditional model aircraft enthusiast, or
the 'commercial operator'. We have already seen instances of foreign
tourists bringing their 'drone' on holiday with them and using
it to take photos of notable landmarks in London. This type of
footage is also shared online via sites such as YouTube."[8]
19. Although the focus of this inquiry is on
the commercial use of RPAS, the implications of their leisure
use are considered in Chapter 8.
Civilian Applications for RPAS
20. We heard many examples of innovative applications
for the civilian use of RPAS which could enhance existing services
and industries. Flirtey, an RPAS delivery company based in New
Zealand, said that it planned to use RPAS to "revolutionise
three industriesonline retail, fast food and logistics."[9]
Amazon has also publicly announced plans to consider using small
RPAS for deliveries.[10]
The British Airline Pilots Association (BALPA) said that, in addition
to transport, RPAS could be used to suspend lightweight screens
to project films or advertising.[11]
Callen-Lenz Associates Ltd and the Professional Society of Drone
Journalists said that RPAS could be used to provide Internet connectivity
in remote locations.[12]
In fact Google and Facebook are both interested in harnessing
this technology to ensure greater access to their web-based services.[13]
21. Mirko Kovac, Director of the Aerial Robotics
Laboratory at Imperial College London said that, if combined with
robotic technology, RPAS could be used to "repair structures
or construct buildings autonomously."[14]
Network Rail Infrastructure Ltd said it was piloting the use of
RPAS for surveillance of railway infrastructure, because it improved
"workforce safety by enabling such surveys to be carried
out from a position of safety".[15]
Carl Robinson, from the British Antarctic Survey, said that RPAS
were being using as "science platforms in order to carry
out Polar research", because of their low cost, availability
and unique capabilities.[16]
22. It is impossible to provide a definitive
categorisation of the different civilian uses for RPAS, since
new uses are being developed all the time. Nevertheless, Table
1 combines a description of the most common applications for civilian
RPAS with some indication of their size and cost. Table

Growth in the civilian RPAS industry
23. The evidence we received confirmed as credible
the estimate by the Aerospace and Defence Industries' Association
of Europe that 150,000 jobs could be created in Europe in the
RPAS sector by 2050.[17]
The Commission said that these new jobs would be spread across
manufacturers, operators and the broader supply chain of enabling
technologies.[18] A market
study conducted in 2014 by Teal Group, an aerospace and defence
consultancy company, suggested that the share of global spending
on RPAS for civilian (as opposed to military) applications could
increase, as a proportion of total RPAS spending, from 11 to 14
per cent in the next decade.[19]
The Commission believes that the RPAS market has the potential
to make companies in all sectors more competitive.[20]
BALPA, EuroUSC and Accenture said that RPAS would put aviation
capability in the hands of "every business on the planet",
enabling them to complete tasks efficiently.[21]
24. The most rapid commercial market growth has
come from the small RPAS sector.[22]
In the UK, this has mainly involved the sale of services, for
example the collection and sale of surveillance data products
and photographs. The Royal Aeronautical Society said that this
trend was set to continue because "the amount of investment
is less, the technology is more versatile, more readily available,
accessible, and easier to use" than existing methods.[23]
Robert Goodwill MP, Parliamentary Under-Secretary of State
for Transport (hereafter referred to as the Minister), said: "The
CAA has experienced a big jump in applications for commercial
use of small unmanned aircraft, and it has issued approximately
670 permissions so far in 2014".[24]
25. There has also been large growth in ancillary
services to the RPAS industry. Resource Group Ltd, a UK based
company training RPAS pilots, said that it had trained more than
300 pilots for small RPAS and planned to train more than 500 pilots
in 2015.[25] André
Clot, Director of EuroUSC, another RPAS pilot training company,
said:
"My company has doubled in nine months.
I was not expecting that. I have a business plan. Twelve months
is too long for a business plan in this business. You have to
revise it every three months."[26]
26. On the other hand, growth in the market for
large RPAS has been slow. The Government said that this was directly
related to "solving the additional technical challenges associated
with flight at greater distances and altitudes, in particular,
the airworthiness requirements and the capability to avoid collisions."[27]
With regard to large passenger-carrying RPAS, BALPA said that
there would be "inevitable resistance" from the public
to flying on a machine where "the person who holds their
life in their hands does not actually sit alongside them".[28]
There would also be little financial incentive to produce a remotely
piloted passenger-carrying aircraft because it would still require
life support infrastructure for passengers and cabin crew, in
addition to the extra expense of building a secure ground base
station for the pilots.
27. However, BALPA did identify some potential
in the cargo sector. It noted that a cargo RPAS would not require
life support equipment, such as pressurisation and air conditioning,
catering, seating, windows or even toilets, as are found in manned
cargo aircraft. Such an unmanned aircraft would thus be "lighter,
cheaper to run, more efficient and easier to build
than
its manned equivalent".[29]
28. Hybrid Air Vehicles Ltd, a manufacturer of
large, long endurance, gas-filled RPAS, forecasted that its Airlander
programme would create 1,800 new jobs within five years and have
employees in the tens of thousands by 2050.[30]
Current RPAS Regulations
PRINCIPLES OF AVIATION REGULATION
29. As aviation developed in the early twentieth
century to become an international activity, so too did the principles
and regulations governing it. The first key principle of aviation
regulation is the categorisation of the airspace which determines
where different types of aircraft can fly. By international agreement,
airspace is designated into classes A-G according to different
types of aircraft operations. The designation indicates the level
of air traffic management service that is provided and the minimum
equipment and pilot competence required to fly. Class A airspace
has a full air traffic management 'separation' service and is
reserved for professional pilots flying sophisticated commercial
aircraft. In contrast Class G airspace is used by pilots of small
aircraft, gliders and micro lights, and there may be no air traffic
management service whatsoever.[31]
30. In addition, sections of the airspace can
be restricted for special purposes, most often for military training
operations or special RPAS operations. Such airspace is generally
called segregated airspace, as it is segregated from other aircraft,
and access is limited to authorised aircraft only. Air traffic
management services may or may not be provided.
31. Today most small RPAS operations are restricted
to Class G airspace below 500ft above ground. While this is not
formally segregated, it is largely free of normal aircraft traffic.
Radar tracking of aircraft is not usually provided in this airspace.
32. A second key principle within aviation regulation
is the separation between regulation of the physical systems (airframe,
engines, flight control software) and of the operation of the
aircraft. Airworthiness regulations refer to the certification
of the systems and includes design, manufacture and ongoing maintenance
to ensure that the aircraft is safe to use. Operational regulations
refer to rules regarding what makes an aircraft safe to operate,
including pilot training and licensing and the use of air traffic
management services.
RPAS REGULATION AT THE INTERNATIONAL
LEVEL
33. The International Civil Aviation Organization
(ICAO) was created in 1944 upon the signing of the Convention
on International Civil Aviation (commonly referred to as the Chicago
Convention), as a UN specialised agency.[32]
ICAO publishes Standards and Recommended Practices (SARPs) which
are intended to assist States in developing national aviation
regulations. Each ICAO member country has a national aviation
agency, or agencies, to oversee the different aspects of civil
aviation, such as pilot licensing or air traffic management services.
34. Under Article 8 of the Chicago Convention,
all RPAS regardless of size are prohibited from flying over another
state's territory without its permission.[33]
35. ICAO set up an Unmanned Aircraft Systems
Study Group (UASSG) in 2007, which brought together experts from
its Member States, stakeholder groups and industry, to discuss
the impact of RPAS on aviation regulation. In November 2014, in
response to the rapid developments in RPAS technology, the UASSG
was elevated to the status of a Panel, and it aims to publish
Standards and Recommended Practices (SARPs) on unmanned aircraft
by 2018.[34] These SARPs
will include guidance on airworthiness, operations and pilot licensing. Table

RPAS REGULATION AT THE EU LEVEL
36. In 2003, the European Aviation Safety Agency (EASA) was
established in Cologne. It is responsible for the airworthiness
and operations of aircraft within the EU. EU Regulation 216/2008
provides that EASA is responsible for civil RPAS over 150kg, leaving
RPAS below 150kg and Member State use of RPAS (military and non-military)
as the responsibility of Member State authorities.[35]
37. EASA is supported by two other agencies,
EUROCONTROL and the European Organisation for Civil Aviation Equipment
(EUROCAE).[36] EUROCONTROL
coordinates the air traffic management services across Europe
and conducts research, while EUROCAE drafts the airworthiness
and operational standards for aircraft.
RPAS REGULATION AT THE UK LEVEL
38. The Civil Aviation Authority (CAA) is responsible
for regulating RPAS below 150kg. The CAA bases its regulations
on the size of the RPAS, with small RPAS categorised as weighing
up to 20kg and light RPAS weighing 20-150kg.
39. The CAA's main legislative tool is the Air
Navigation Order (ANO) 2009, which draws together legislation
covering all aircraft, air traffic management, crew, passengers
and cargo.
40. The application of articles of the ANO to
military, commercial and leisure RPAS operations is explained
in 'CAP 722', a guidance document generated by the CAA.[37]
It describes the safety requirements that have to be met in terms
of airworthiness and operational standards before an RPAS is allowed
to operate in the UK. The document is widely referred to by other
states when developing their own regulations. Box 1 outlines the
provisions of the ANO relating to RPAS. Box
1: RPAS and the Air Navigation Order 2009
Article 138, which applies to all aircraft, including RPAS, irrespective of weight, stipulates that "a person shall not recklessly or negligently cause or permit an aircraft to endanger any person or property".[38]
Other provisions which apply to all RPAS are:
· A person must not cause or permit any article or animal (whether or not attached to a parachute) to be dropped from a small unmanned aircraft so as to endanger persons or property (light RPAS under Article 129; small RPAS under Article 166).
· The person in charge of a small unmanned aircraft may only fly the aircraft if reasonably satisfied that the flight can be made safely (light RPAS under Article 87; small RPAS under Article 166).
Articles 166 and 167 state that for small RPAS (<20kg) the following rules apply:
· The person in charge of a small unmanned aircraft must maintain direct, unaided visual contact with the aircraft sufficient to monitor its flight path in relation to other aircraft, persons, vehicles, vessels and structures for the purpose of avoiding collisions. RPAS should be flown within the visual range of the remote pilot or observer, or a maximum range of 500m, whichever is less.[39]
· Small RPAS are limited to fly to a maximum height of 400ft.
· Small RPAS are prohibited from flying in air traffic controlled airspace (Class A-E) and aerodrome traffic zones without authorisation of an Air Traffic Control (ATC) unit.
· The pilot is required to seek permission from the CAA for aerial surveillance or data gathering work.
· Small RPAS used for surveillance should not be flown:
· over or within 150m in any direction of any densely populated areas;
· within 50m of any person (other than the remote pilot; or persons under control of the remote pilot), vessel, vehicle or structure (30m during take-off and landing).
· Small RPAS are exempt from the normal Air Navigation Order requirements for airworthiness certification, flight crew licensing and the 'rules of the air' although they must be operated safety.
All Articles of the ANO apply to RPAS between 20-150kg. Operators are required to certificate airworthiness, have a permit to fly or a licensed flight crew and to follow the Rules of the Air. If this is not possible, the CAA may be prepared to issue an Exemption under Article 242 of the ANO.

The Commission's Communication
41. The Communication states that greater access to the airspace
over time is essential to achieving growth in the RPAS industry.
For large RPAS this means integrating operations into the non-segregated
airspace shared with other users and, where appropriate, controlled
by air traffic management services. For small RPAS this means
increased access to airspace over congested areas, which Commission
officials described as "civilian habitat" or "cities".[40]
The future success of the RPAS industry as a whole depends on
flight operations which can take place over greater distances
beyond visual line of sight of the pilot. The Roadmap for the
Integration of RPAS into the European Aviation System said:
"all experts agree that the insertion of RPA in airspace
will be gradual and evolutionary", and outlines a timeframe
for action between 2013 and 2028 to accomplish full integration
of RPAS into the European airspace.[41]
42. The Communication sets out plans to create
a single market for RPAS by harmonising the regulations for the
airworthiness and operations of RPAS. This particularly affects
the small RPAS industry which is developing in different ways
across Member States. The Commission aims to do this by extending
the competence of EASA to include RPAS with a mass below 150kg.
43. In order to meet the technology needs for
RPAS, the Communication recommends streamlining Research and Development
projects to prioritise the most pressing technological challenges,
such as 'detect and avoid' technology, critical to both large
and small RPAS.[42] The
Commission plans to achieve this by including RPAS-specific projects
within the EU's existing Single European Sky Air Traffic Management
Research Joint Undertaking (SESAR JU).
44. Alongside the progressive integration of
RPAS into European airspace from 2016 onwards, the Communication
suggests plans to encourage public debate about measures to address
societal concerns. These include perceptions of safety, data protection,
security and liability in case of an accident.

Commercial manned aircraft operations are largely concentrated
in airspace classes A, B and C where a full 'separation' is provided
by air traffic management. Small general aviation aircraft, gliders
and parachutists mostly operate in Class G, but also in E and
where the air traffic management service is limited or non-existent.
In such airspace the pilot of each aircraft is responsible for
keeping well clear of other traffic. Today, most small RPAS operations
take place at a height of less than 400 feet above ground level.
Airspace at this height is mostly designated as Class G airspace
but near to airfields it may be one of the air traffic management
controlled classes, for example, B or D. Back

'Detect and avoid' technology would enable an RPAS to sense objects
in the air and automatically avoid a collision. The development
of this technology is seen as the prerequisite to increasing access
for RPAS to the airspace. Back
