Any machine capable of flight without on-board human control is an Unmanned Aerial Vehicle (UAV) or Unmanned Aerial System (UAS). This includes drones, model aircraft, and Remotely Piloted Aircraft (RPA).
Civilian UAV usage varies from filming, photography, surveillance, patrol, parcel delivery, and recreational flying.
Increase in civilian use over the last two decades has caught regulators flat footed. As a result, most countries have no specific laws to regulate design, manufacture, acquisition, usage, and operations. UAVs are over-the-counter items, affordable and available for purchase by private consumers regardless of age, intention, and operational knowledge.
UAVs are a potential danger to manned aviation and the public because:
– They do not go through meticulous design, production, and certification processes. A power and communication link loss for instance, could turn any UAV into a lethal object.
– It is not mandatory to carry safety equipment like transponders or strobe lights, so most UAVs are neither visible nor do they communicate with Air Traffic Control (ATC) or other aircraft.
– UAV operators are not licensed by National Aviation Authorities so their operational competence cannot be assessed.
According to the Federal Aviation Administration (FAA), there were 765 reports of UAV possible encounters with manned aircraft for the period 13th Nov 2014 to 20th August 2015.
On May 30, 2014, a pilot of an ATR-72 landing at London South-end Airport reported having sighted a drone flying within 25 meters of the aircraft. He filed Airprox report No. 2014073 with the United Kingdom Airprox Board.
On January 23, 2015, airspace around Dubai International Airport was shut down for close to one hour due to recreational unmanned vehicles in the air navigation passage of planes.
Beyond civil aviation, UAVs in the wrong hands could be used as weapons. This raises safety and security concerns. Privacy, copyright, and data protection issues arise when UAVs are used for unauthorized surveillance, photography, and video recording.
The International Civil Aviation Organization (ICAO) recognizes UAV operations alongside manned aircraft in Article 8 of the International Convention on Civil Aviation, and in annex 2, 6, 7, and13.
In 2015, ICAO published technical and operational guidance material in Document 10019 (Manual on Remotely Piloted Aircraft Systems). This document excludes model and recreational UAVs.
Remotely Piloted Aircraft Systems (RPAS) have three components: A Remotely Piloted Aircraft (RPA), Remote Pilot Station (RPS), and Command and Control (C2) link. They are capable of flying long distances Beyond Visual Line of Sight (BVLOS), Beyond Radio Line of Sight (BRLOS), and across international borders. RPA can be controlled by different RPS at a time during flight.
Document 10019 addresses design, certification, registration, operations, airworthiness, licensing, flight rules, hand over/coordination procedures from one RPS to another, safety management, and licensing standards.
The guidelines in Document 10019 address unmanned aircraft involved in international civil aviation. Though possible, they are complex, require training, infrastructure, and will take time for Contracting States to adopt and implement.
To ensure safety, UAVs should meet the same safety and operational standards as manned aircraft. However, in many countries, regulatory regimes have not kept pace with demand and are yet to come to speed with operational regulation.
Below is an analysis of UAV specific regulatory and/or technical guidance materials in selected countries (as of January 31, 2016).

Save for Egypt which passed legislation more than three decades ago, UAV regulation is a new area, constantly evolving, yet to be standardized and tested.
The differences from absolute prohibition, tough criminal sanctions to lack of regulation shows that many countries are yet to understand and/or appreciate UAV operations. The different approaches have implications;
Absolute prohibition denies society the advantages associated with drone technology for instance, conducting inspections where it is unsafe for human beings like in radioactive or flooded areas. High operating costs associated with operating fixed wing aircraft or helicopters for aerial surveys/photography can be reduced by UAV operations. Absolute prohibition denies society this cost saving opportunity.
Harsh criminal sanctions, although justified in densely populated urban environments like Singapore, could undermine just culture and voluntary occurrence reporting, which are essential to aviation safety.
Lack of regulation is no bar to acquisition and use. In Uganda for instance, several media houses have imported UAVs for aerial filming and photography. Without registration, licensing or insurance requirements, it might be impossible to trace an operator whose UAV has flown into private property, over an aerodrome, has collided with manned aircraft, or has simply flown out of control in the process injuring or killing an unfortunate bystander. Whereas such scenarios may be attributed to human/pilot error, there is a higher possibility of the same occurring due to absence of licensing regulations that help assess operational/pilot competence.
Mandatory insurance cover is vital in the event of damage to property, injury or death arising out of UAV operations.
National security might come under threat when drones are flown into or over government installations. Data collected could be used by criminals or terrorists to plan attacks. In such scenarios, security agencies might find difficulty in tracking down operators because of lack of registration records.
Requiring approvals from multiple state agencies before operations is unnecessarily bureaucratic. Not only does this waste valuable time, it might encourage corruption to speed up approvals, especially in third world countries where the vice is entrenched. The possible increase in time and costs could erode the convenience and economy associated with UAV technology.
Just like cellular phones and social media, UAVs are part of our society, with ever increasing demand and usage. It makes no sense for regulators to prohibit or ignore societal demands. Permitting use within defined parameters with detailed regulation and enforcement mechanisms (like United Kingdom and United Arab Emirates) is the only way safe and orderly operations can be guaranteed.
