Unauthorized Flying of Drones Near Airports

BACKGROUND

Drones have recently become more affordable to the public as their performance in
terms of height, speed, and distance has greatly improved. Consequently, the hazard
posed by the flying of unauthorized drones near airports worldwide has also increased.
Available data indicate that the frequency of drone activity, both authorized and
unauthorized, in the vicinity of airports continues to rise significantly

. In the UK alone,
for example, thousands of drone operations are detected near airports every month.
Most unauthorized occurrences are accidental and harmless to civil aviation. They are
often linked to the operator’s lack of familiarity with the rules of the air or a loss of
control.

However, drone operations can also have a malicious intent, such as the desire
to create disruption or, in the worst-case scenario, to cause harm.
It is very difficult to distinguish between the different types of operations and track
them accurately. IFALPA, ECA, and IFATCA are extremely concerned that some of those
numerous drones could end up, either deliberately or not, in the direct flight path of an
aircraft on arrival or departure, with catastrophic consequences, as demonstrated by a
UK study published in 2017.

CURRENT MITIGATING MEASURES

Several airports have been responding to the sighting of unauthorized drones by
stopping operations for a period, leading to massive disruption. The most dramatic
example was the closure of London Gatwick between 19 and 21 December 2018,
following reports of drone sightings close to the runway. This led to hundreds of flights
being cancelled, affecting over 100,000 passengers. Stockholm Arlanda has also closed
on several occasions due to drones operating in the vicinity of the airport. Closing
airports has huge financial and operational implications (diversions, stranded
passengers, etc.), and has not proved successful in stopping unauthorized drones. It
should not be considered as a sustainable solution.

Guidance material on the impact of unauthorized UA event close to aircraft and
aerodromes has been produced as a result of an industry initiative started in 2020 and
coordinated by IATA, with the participation of organizations such as ACI, IFALPA, ECA,
IFATCA, ANSPs, and CAAs.
Another option which has been explored is the installation of technological means to
detect and disable unauthorized drones. Such technology already exists at both London
Gatwick and London Heathrow, amongst others. Depending on the type of equipment,
unauthorized drones can be positively identified, tracked, jammed, or even destroyed.
However, there is no international Standard on the design and operation of these
systems, and their cost makes them largely inaccessible to most airports. Moreover, the
possible undesired consequences of their use in terms of magnetic interference and
collateral damage of disabled drones should not be underestimated.

POSITION

IFALPA, ECA, and IFATCA believe that the best line of defence is preventing
unauthorized drones from flying near airports in the first place. However, current
legislation in many, if not most, States is still an insufficient deterrent to the
unauthorized flying of drones near airports, as demonstrated by their steady increase.

IFALPA, ECA, and IFATCA therefore call for States to establish and implement further
regulations, practices, certification standards and procedures, and appropriate penalties
for offenders, in order to safeguard civil aviation against such activities.
Public awareness campaigns should be organized with the aim of educating the public
at large as to the risks and implications of flying drones near airports.

These campaigns
have been very successful in decreasing the number of laser illuminations of aircraft, and
the same could be achieved to prevent the inadvertent infringement of airspace.
Drone manufacturers should also play their part in safety improvement by the fitting of
geo-fencing systems, registration numbers, and/or electronic signatures. Furthermore,
IFALPA, ECA, and IFATCA believe that increased efforts should be made to thoroughly
research technology regarding drone detection and counter-drone measures.

Sightings of drones likely to interfere with the flight path of aircraft should be subject to
an immediate and standardized reporting process including ATC, airport Authorities,
local police and, where relevant, flight crews operating in the area. Appropriate follow-
up by law enforcement agencies should be ensured.
Finally, IFALPA, ECA, and IFATCA believe that any unauthorized flying of drones near
airports that jeopardizes the safety of aircraft should be classified as a “serious incident”

(as per the ICAO Annex 13 definition) and be subjected to a thorough investigation by
the relevant Authorities.
When there is malicious intent; it should further be classified as an “act of unlawful
interference” as per ICAO Annex 17.
