Enforcement measures
5.1
Not only are RPAS capable of congesting busy airspace and breaching
privacy barriers; the technology can also cause disruptions to important
emergency operations and health services. Beyond this, RPAS in the hands of
non-state actors may even pose a threat to the national security of significant
public buildings and critical infrastructure.
5.2
This chapter details incidents and occasions where RPAS are increasing
used inappropriately, and explores how the restriction or prohibition on the
use of RPAS in certain airspace could assist in enforcing the safe and lawful
use of RPAS within the national aviation system. The role of local government
and police is also discussed.
Vulnerable airspace
5.3
Submitters highlighted a number of vulnerable areas that would benefit
from more stringent RPAS-use restrictions and greater enforcement, including
helicopter landing sites, busy airspace, and emergency and safety operation
areas.
Helicopter landing sites
5.4
NSW Ambulance informed the committee that helicopter landing sites at
hospitals are vulnerable to RPAS incidents due to having busy low-flying zones.
It noted that NSW Local Health Districts have 172 helicopter landing sites
(HLS) that are used in a retrieval and inter-hospital transfer capacity, while NSW
Ambulance Helicopter Emergency Medical Services aircraft regularly use sporting
fields and public ovals to access pre-hospital accident sites. Yet, it
recognised that RPAS operators would most often not be aware of hospital HLS
around the country, and specifically the approach and departure paths to these
HLS.[1]
5.5
As ambulance helicopters fly at lower levels than along coastal
corridors, a collision with RPAS could have 'catastrophic consequences'. NSW
Ambulance explained the context:
...in the most vulnerable stage of flight, the landing, pilots
will be fully focussed on handling the aircraft, configuring the aircraft for
landing, and ensuring the flight path and landing area are clear of fixed
obstructions. Detecting UAV will be difficult and will be complicated further
by the existing visibility at the HLS or landing area.[2]
5.6
Both Captain Phillip Stevens and Captain David Booth informed the
committee that the risk of catastrophe in such a scenario is heightened by the
fragility of the helicopter tail rotor.[3]
According to Captain Booth:
The risk to tail rotor is significant. It is a very fragile
part of the helicopter. We have had many longstanding pilots tell us that a
two-kilo strike to a tail rotor, from their experience seeing tail rotor damage
in their careers, would almost certainly lead to an autorotation or a loss of
control...we think the helicopter end of the industry is really the most
vulnerable to these events.[4]
5.7
In December 2017, Queensland Health noted a rise in the number of RPAS
sightings reported by aeromedical crews whilst on mission. In some instances,
crews had taken additional measures to avoid RPAS hovering near helicopter
landing pads. In response to the growing concerns, Queensland Health launched a
digital campaign to remind families that all hospitals in the state were 'drone
free' zones. Noting that as many as 500 patients arrive at hospitals by
helicopter over the holiday period in Queensland, the campaign sought to remind
RPAS operators not to fly within a 5km radius of any Queensland hospital.[5]
Busy airspace
5.8
Civil Air Australia explained that the busy airspace around major cities
is the most likely to see RPAS collide with manned aircraft.[6]
As such, RPAS users that may not be familiar with controlled airspace
boundaries or airspace restrictions, are in danger of causing a serious
incident.
5.9
CASA's aviation magazine, Flight Safety Australia, recently identified a
number of hotspots where the potential for an RPAS collision with light
aircraft, helicopter and regular public transport (RPT) aircraft has increased.[7]
Included in the list were Sydney Harbour, Melbourne Docklands, Brisbane
Southbank, the Gold Coast and Cairns.[8]
5.10
In line with this advice, the ATSB informed the committee that
approximately 40 per cent of reported occurrences between July 2016 and June
2017 took place in the Sydney basin.[9]
In January 2018 alone, there were 11 RPA near-encounters with manned aircraft,
six of which occurred within 20 nautical miles of Sydney Airport.[10]
Anecdotal evidence also shows a large number of RPAS flying within the flight
path of the Gold Coast International Airport.[11]
5.11
Airline Rex expressed its concern about collisions near airports around
the country:
The area in which Rex views as the greatest threat to commercial
airline operations is in the area of small unmanned aircraft operating in the
vicinity of airports. Rex has had reports from its pilots, and persons on the
ground, of illegal operations in the vicinity of airports, and on flight
approach and departure areas.[12]
5.12
VIPA added:
Launching a drone close to an airport, particularly in
proximity to an uncontrolled aerodrome exposes aircraft (which are often jet
powered) to the risk of collision which could result in substantial damage,
loss of control and potentially, loss of life.[13]
5.13
Many aviation industry stakeholders echoed these concerns.[14]
Captain Murray Butt of AusALPA revealed that:
There is not a professional pilot in Australia who does not
harbour some degree of concern about the risks posed by unmanned aerial systems
and how these risks are being managed.[15]
5.14
The increased number of RPAS operating in busy airspace has heightened
the risk of an accident or incident. Whilst the absolute prohibition of RPAS in
these areas may be unrealistic, Civil Air Australia suggested that RPAS
operations in such airspace could be limited to commercial RPAS users.[16]
Emergency and safety operation
areas
5.15
Many witnesses argued that the regulator should take stronger preventative
action to ensure that RPAS remain clear of public safety operations. At a
public hearing in Brisbane, Mr Michael Manning of Drone Solutions told the
committee:
Last year in July [at Burleigh Heads on the Gold Coast] a
Westpac rescue helicopter had a near miss with a drone. It was all over the
news and the pilot described how close he came to a collision. I think he said
50 metres or thereabouts...
Why are we waiting for the first fatality before we take
strong action to prevent this type of activity? When the drone incident
happened at last year's Winter Olympics, many European countries, including
Slovenia, closed down all drone activities almost overnight. We want to prevent
this from happening in Australia but we need to urgently fix what is now broken.[17]
5.16
The Victorian Department of Environment, Land, Water and Planning
informed the committee of four instances during a single season where hobbyist RPAS
operators had caused a nuisance during fire suppression operations. Mr Brendan
Zwanikken, Manager of Aviation Services Unit at the department reported:
Firefighting aircraft, when they are conducting bombing
operations in particular, fly below 400 feet. They are getting down to 100 or
200 feet, which is where CASA currently allows unrestricted [RPAS] operations...
Victoria has had four incidents in the autumn burn season where RPAS have been
flying over planned burns. Luckily, those planned burns were ground ignition,
not aerial ignition. However, we have seen that there is a real threat, should
we be doing aerial ignition from helicopters, in that environment...However, New
South Wales did have an incident in October last year where, during fire
suppression operations, the RPAS were flying over the fire line and bombing
aircraft had to climb suddenly to avoid it.[18]
5.17
Mr Zwanikken went on to explain the impact of RPAS on emergency
operations:
Currently, the way we deal with unauthorised RPAS flying over
emergency areas is that we will ground the aerial fleet. If we are bombing in a
fire suppression operation and someone detects a RPAS, we will stop all aerial
bombing, or flights, until the pilot for that RPAS is found.[19]
5.18
The grounding of emergency aircraft and cessation of operations in
emergency situations in order to avoid a collision with an RPAS adversely
impacts both the emergency operation itself and public safety more generally.[20]
The NSW Government and NSW Ambulance expressed concern that, not only are
aircrew, medical crew and patients at risk when operating in uncontrolled
environments, but the unauthorised use of RPAS also 'increases the potential of
shutting down aerial firefighting operations'.[21]
5.19
The point was made that, while the regulations prescribe that RPAS
should not be operated in a manner that causes a hazard to people or aircraft,
and the standard operating conditions require that all RPAS remain clear of
public safety operations, many such operators are 'not necessarily aware of the
regulations', whilst others will 'flaunt them'.[22]
General Manager of the National Aerial Firefighting Centre, Mr Richard Alder,
told the committee that the 'risk is likely to significantly increase, not only
as drones proliferate, but as their capabilities increase as well'.[23]
Airspace around public buildings
5.20
In addition to the airspace over major cities, emergency operations
sites, and HLS, the committee considered that RPAS operating over significant
public buildings may also be a cause for concern.
Airspace restrictions in the United
States
5.21
In the US, the National Capital Region, where the Capitol and the White
House are located, is classed as a Special Flight Rules Area, meaning that
additional flight restrictions apply to the airspace. The rules were put in
place after the 9/11 attacks, and limit aircraft operations to those with FAA
and Transportation Security Administration approval. Violators found to breach
these rules are subject to stiff fines and criminal penalties.[24]
5.22
The airspace around Washington D.C. is more restricted than in any other
part of the US. However, in 2017, similar restrictions were imposed by the FAA
over a number of other public buildings. On 5 October 2017, at the request of
security and law enforcement agencies, the FAA used its authority to restrict RPAS
flights up to 400 feet within the lateral boundaries of 10 Department of
Interior sites, including the Statue of Liberty and Mount Rushmore.[25]
In December 2017, further restrictions were issued over several Department of
Energy facilities in a number of states. The FAA is also considering requests
from other federal security agencies to implement additional restrictions.[26]
5.23
Drawing on the US experience, the committee turned its mind to the
imposition of RPAS flight restrictions around significant public buildings in
Australia.
Airspace restrictions in Australia
5.24
Noting the stringent restrictions in place in Washington D.C., the
committee was alarmed to hear from CASA that '[t]he airspace over or in the
vicinity of Parliament House is not declared as a prohibited area'.[27]
CASA stated that:
There is currently no designated airspace for prohibited,
restricted or danger areas (as defined in the Airspace Regulations 2007) over
or in the vicinity of Parliament House.[28]
5.25
Instead, as Parliament House falls within the control zone of Canberra
Airport, it is 'not appropriate' to fly an RPAS within its precinct.[29]
5.26
The fact that Parliament House is not recognised as a prohibited area
raised questions for the committee, particularly in light of an incident in
June 2017 when an RPAS was reported to have flown over Parliament House, and a
nearby sports oval, without authorisation.[30]
In addition to flying the RPAS over a public building, this action appeared to
be in breach of the RPA standard operating procedures, including flight over a
populous area, and within 30 metres of people.
5.27
However, CASA responded by stating that recreational RPAS operators are simply
'encouraged to adhere to the standard operating conditions'. It noted that operations
under the excluded category of the regulations 'are also not restricted by
location'.[31]
As such, there is no distinction between the airspace over public buildings, schools,
parks, and other public spaces, unless distinguished by 'a significant density
of population' to be deemed a 'populous area' under the standard operating
conditions.[32]
5.28
The committee considered that the seemingly unregulated airspace above Parliament
House raises serious questions about the security of critical infrastructure in
Australia. The lack of clear restrictions appears to be inconsistent with
aviation safety principles and national security standards. The committee
therefore sought to understand the process by which certain airspace can be prohibited
from RPAS operations. Whilst airspace restriction is not the only measure
highlighted in evidence to effectively regulate safe RPAS use, clearly defined
prohibitions could act as a disincentive for oblivious operators who may
otherwise be unaware of the dangers posed by their device.
Process for prohibiting RPAS in
certain airspace
5.29
The committee was informed that CASA is the agency responsible for
exercising the powers provided under the Airspace Act 2007 and Airspace
Regulations 2007. The CASA Office of Airspace Regulation regulates and
administers all Australian airspace, including prohibited, restricted and danger
areas where certain types of activities take place that may present a risk to
aviation activities.[33]
5.30
CASA stated that, according to Regulation 6 of the Airspace
Regulations 2007, it 'must not declare an area to be a prohibited area
unless...it is necessary for reason of military necessity to prohibit the flight
of aircraft over the area'.[34]
5.31
CASA CEO, Mr Shane Carmody went on to explain:
I'm the safety regulator, so my remit is around safety. We
are able to make declarations on airspace, if someone puts something to us, but
we have no expertise on security in Parliament House.
...I would expect a formal request from a security agency, the
Federal Police, a privacy organisation or the Attorney-General to make a
declaration on airspace about declaring airspace at a particular time.[35]
5.32
The Department of Defence (Defence) added that applications for airspace
restriction are subject to submission of an Airspace Change Proposal that would
include consultation and development of a safety case to justify such
declarations by CASA.[36]
5.33
The IALPG cautioned that, in the absence of an appropriate regulatory
solution to enforce safe RPAS operation and effectively restrict airspace,
anti-drone technologies are likely to flourish, leading to the
commercialisation of security and a loss of control on the part of aviation
regulators.[37]
5.34
This was supported by evidence of the thriving counter-drone industry,
notably led by an Australian defence company called DroneShield. The committee
heard that, whilst airspace restrictions were imposed for the 2018 Commonwealth
Games in the Gold Coast,[38]
the Queensland Police were also equipped with an 'arsenal' of drone guns,
designed to emit a jamming signal to cause RPAS to go into emergency mode and
either land in a designated area or return to their starting point.[39]
5.35
The importance of employing complementary technological solutions for
RPAS regulation was a consistent theme throughout the inquiry. Technology-based
compliance measures are discussed further in Chapter 6.
Local government initiatives
5.36
In response to growing safety and privacy concerns, local governments
have become increasingly active in restricting and banning RPAS operations in
public spaces.
5.37
In 2015, Leichhardt Council in Sydney became the first council in
Australia to ban RPAS in parks and public spaces, including playgrounds, to
protect children's safety and privacy.[40]
A number of councils across Australia now have by-laws in place to restrict RPAS
use on local government land including public reserves, parks and foreshore
areas.[41]
5.38
IALPG was of the view that local councils can and should be integral in
shaping the culture of RPAS operations, stating:
...the regulation of drone activity at a local level sends a
powerful message to users about potential dangers of misuse, the level of
responsibility such users would have to those they accidentally injure, and
help train community members to understand the power of and maturity required
to safely and responsibly operate when the possibility exists to come into
accidental contact with people, vehicles, wildlife, or infrastructure.[42]
5.39
During discussions on the importance of signage and public information,
representatives from the Australian Airports Association acknowledged that
there was scope for local airports to also do more. Mr Simon Bourke, Policy
Director, drew the committee's attention to jurisdictions that have begun to
engage in restricting areas for RPAS use:
I know Cairns Airport identified some parkland and got in
touch with local council and put in a no-fly-zone for drones and some signage
to that effect. There are several airports that have done that based on their
own risk assessments, the terrain around the airport and the prevalence of
usage around that. So it is being looked at.[43]
Delegation of enforcement powers
5.40
The primary challenge before local councils and airports, and indeed at
a national level, is that of enforcing compliant RPAS operations. As a case in
point, while bans on launching an RPAS within the perimeter of a park can be
policed by a council official, there is little that officers can do when an
RPAS is launched outside of a park.[44]
5.41
While CASA emphasised that there are rules already in place, including
the 30 metre rule and a direction not to fly over crowds or groups, it
also recognised that it would be difficult to find and charge the offender if
there was a breach. As Mr Peter Gibson, a CASA spokesperson, noted in 2015:
If people are concerned about breaches of privacy they can
report it to the police but you still have the problem of identifying who was
operating the drone.[45]
5.42
One solution already discussed in Chapter 4 is the establishment of a
registration system that would allow the operator of the RPAS to be traced and
penalised. In addition to a system of registration, a number of submitters
supported the provision of additional powers to local authorities.
5.43
The Australian Certified UAV Operators suggested that local authorities
be granted additional powers to impose and enforce RPAS regulation, including the
examination and investigation of breaches; confiscation of equipment; and the
issuing of on-the-spot fines if necessary.[46]
This recommendation was also supported by the Regional Aviation Association of
Australia, which expressed the view that federal and state police are 'best
placed to deter, detect, investigate and...pursue' unsafe or unlawful RPAS
operations.[47]
5.44
Defence added:
It would be useful from a legislative/regulative perspective
to positively authorise electronic, physical or other measures to stop,
disrupt, bring down or prevent UAS from being utilised unlawfully. Such a law
could be extended to other Government authorities such as Defence or Border
Force to support the police and provide protection to other sensitive
Government or agency sites.[48]
5.45
In the US, new laws passed on 7 June 2017 allowing authorised agencies
and agency representatives to 'use reasonable force to disable, disrupt, damage
or destroy a UAS that poses a threat to safety or security'. This includes
detecting and monitoring RPAS that are suspicious.[49]
5.46
The UK has put in place similar measures, with the Department of
Transport and the Civil Aviation Authority recently announcing a proposal to
increase police powers to allow officers to investigate RPAS misuse.[50]
For the purposes of safety and security, the new rules will permit police to
order RPAS operators to ground their devices, and demand registration
documentation or RPAS parts if suspected to have been used to commit an
offence.[51]
5.47
CASA told the committee that it is aware of evolving enforcement actions
being taken by local and state government agencies to limit or prohibit the use
of RPAS in particular areas. It expressed support for local efforts, and
stated:
...local law enforcement authorities are generally in a better
position than CASA's operational and investigative officers to respond in a
timely way to actual, apparent and alleged contraventions of the safety
regulations.[52]
5.48
To this end, CASA highlighted to the committee a forum that it
facilitated in November 2017 with state, territory and federal law enforcement
agencies. The aim of the forum was to discuss the development of a standardised
approach to instances and/or reports of local RPAS-related breaches. This approach
may include the issuance of aviation infringement notices, and criminal
prosecutions.[53]
According to CASA, the progression of this work 'is ongoing and is strongly
supported by participating law enforcement authorities'.[54]
