At first sight, they look quite intimidating; however, it’s crucial to remember that they are not a risk if used properly. Similar to using any other mode of public transportation, the risks related to drone use can be minimized by following the guidelines and sticking to applicable laws. Watch the recording of our webinar “Connected Skies” to hear about drone laws, connected drones, drone delivery, and how drones are leveraging the power of mobile and satellite connectivity, and more.

  • However, this term doesn’t apply to autonomous aircraft, which would still be called UAVs.
  • However, songbird surveys were conducted by RPAS-based bioacoustic monitoring , and echolocation calls of Brazilian free-tailed bats were recorded .
  • This session will look at the current vertiport concepts and environments.
  • A case study was the recording of the courtship and mating behavior of the green turtle in the western Gulf of Mexico .
  • Though remotely positioned, the remote pilot still has an onboard-the-aircraft view via a camera feed sent to goggles or a monitor.

However the mechanism does not scale well to larger aircraft, which tend to use a conventional single rotor with collective and cyclic pitch control, along with a stabilising tail rotor. Any aircraft intended to be flown without a pilot on board is referred to in the Convention on International Civil Aviation , signed at Chicago on 7 December 1944 and amended by the ICAO Assembly as a “pilotless aircraft”. Since the drone industry is still in its nascent stage, we can expect the language surrounding it to evolve further in the next few years. The FAA, for example, has asked its Drone Advisory Committee for recommendations on terms that promote inclusion.

RPAS Use in Extreme Environments: Applications on Arctic and Antarctic Research

Unmanned Aircraft System includes a UAV, a ground controller and a system of command and control data link between the two. Junda J., Greene E., Bird D.M. Proper flight technique for using a small rotary-winged drone aircraft to safely, quickly, and accurately survey raptor nests. Johnston D.W. Unoccupied aircraft systems in marine science and conservation. The shape of the seal was recognizable rpa accounting use cases in the thermal image, similar to the higher-resolution RGB image . To retrieve the seal size, temperature contours with 1 °C intervals were delineated as polygons using ArcGIS . The smallest change in the area of polygons between adjacent temperatures indicating the highest thermal contrast was considered as the threshold temperature, i.e., 16 °C, for determining the boundary of the seal body .

What are RPAs

The EU Commission is now conducting a survey online, to gather information in a manner we think may lead to steerage issues. The unprecedented growth of drones or RPAS , within the toy, hobby and professional markets shows no sign of slowing down as system developments are making RPAS more affordable and accessible. I am sure that many people will have recently received one for Christmas and be eager to see what it can do. The commercial aircraft in our skies use an intricate and highly structured route network which allows them to fly safely and efficiently.

For remote human control, a camera and video link almost always replace the cockpit windows; radio-transmitted digital commands replace physical cockpit controls. Autopilot software is used on both crewed and uncrewed aircraft, with varying feature sets. UAVs were originally developed through the twentieth century for military missions too “dull, dirty or dangerous” for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include forest fire monitoring, aerial photography, product deliveries, agriculture, policing and surveillance, infrastructure inspections, entertainment, science, smuggling, and drone racing. As experience is gained and technical capability grows, RPAS will undoubtedly transition into all areas of the airspace, as well as provide new solutions that will be adopted by manned aviation.

Modern UAVs

It is because flying certain UAVs requires more skill than any simple remote control could offer. In addition to skills such as hover time and line-of-sight communication, pilots operating RPAs must first have many hours under their belts to fly them safely and legally not to endanger anyone on the ground below. Consumer drones are also widely used by military organizations worldwide because of the cost-effective nature of consumer product. In 2018, Israeli military started to use DJI Mavic and Matrice series of UAV for light reconnaissance mission since the civil drones are easier to use and have higher reliability.

Aircraft certification is critical for access in the conventional aviation system. This session will look at the approach to certification contained in Annex 8 with a focus on how to address the key components of the RPAS system, namely the remotely piloted aircraft, remote pilot station, and C2 Link. Airworthiness experts from States and industry will discuss the major components of an RPAS system, and how they intend to certify them.

C2 Link

Showcasing a diverse set of current and near-term operations and training experience from around the world that highlight the need for a comprehensive and harmonized regulatory framework to support growth and development. This session will provide an overview of the RPAS-related technical standards, whether under development or already published, by other standards developing organizations . How will these standards apply to certification efforts, and how can they be utilized by CAAs/States and industry? SDOs will share their completed and ongoing efforts as well as their insights and methodologies in developing RPAS-related material.

Superior drone technology, specifically the Bayraktar TB2, played a role in Azerbaijan’s successes in the 2020 Nagorno-Karabakh war against Armenia. Soviet researchers experimented with controlling Tupolev TB-1 bombers remotely in the late 1930s. The Israeli Tadiran Mastiff, which first flew in 1975, is seen by many as the first modern battlefield UAV, due to its data-link system, endurance-loitering, and live video-streaming.


Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F., “Fault-tolerant cooperative navigation of networked UAV swarms for forest fire monitoring” Aerospace Science and Technology, 2022. The use of UAVs is also being investigated to help detect and fight wildfires, whether through observation or launching pyrotechnic devices to start backfires. The global UAV market will reach US$21.47 billion, with the Indian market touching the US$885.7 million mark, by 2021. Solar-powered atmospheric satellites (“atmosats”) designed for operating at altitudes exceeding 20 km for as long as five years could potentially perform duties more economically and with more versatility than low Earth orbit satellites. Likely applications include weather monitoring, disaster recovery, Earth imaging and communications. Overheating and subsequent engine failure is the most common cause of drone failure.

Thermal cameras can be used together with high-resolution RGB cameras to complement the lower spatial resolution of a thermal detector, e.g., 640 × 512 pixels . Although small-scale surface features are omitted in thermal images due to the larger pixel size, the thermal contrast between wild animals and the background land covers enables identifying individuals or aggregations . The thermal contrast yielded from differences in the surface temperature vary from the composition of land cover with a combination of environmental factors, such as the duration of exposure to the sun and shadow casting from the local topography. Therefore, for optimal monitoring, the timely acquisition of a thermal image preventing a homogenized scene temperature is crucial to maximize the detectability of target animals by enhancing the thermal contrast between targets and backgrounds . The command and control link is the data link between the remotely piloted aircraft and the remote pilot station for the purpose of managing flight.

What are RPAs

Particularly, in the Arctic and Antarctic regions, the detection capability of endothermic animals can be emphasized from the higher thermal contrast between targets and backgrounds . For instance, echolocating bats can be sampled by designing the vehicle with noise-cancelled flying . In marine animal studies, an RPAS video survey has advantages in minimizing human-induced disturbance and reducing the cost of observing the animals compared to traditional monitoring methods using ships. In addition, new algorithms have been developed to detect swarming behavior for the aggregation and foraging of social animals .

Lee et al. identified the approximate size of pink-footed geese by calculating the longest length of the convex hull of manually selected isothermal polygons depicting individual birds. Aerial photographs from RPAS are also efficient for counting herd numbers. As animals often form groups in their natural habitats, high-resolution images are effectively acquired within an adequate operation radius of RPAS (e.g., a few kilometers) and used to estimate the population size for large animals, like hippos and sharks . Thus, RPAS can be applied to examine the density or distribution of cryptic or endangered species. RPAS could save time and help with identifying whole raptor nestlings and eggs or Sumatran orangutan nests , both located at the tops of trees.

What is an RPAS?

RPAS-based images may miss actual animal figures depending on the light conditions and environmental obstacles, e.g., clouds, leaves, and topographic hindrance. Yet, we suggest using an RPAS for collecting on-site material to support survey data for various purposes and expect using RPAS in wildlife studies will be expanded continuously according to its potential uses and RPAS and sensor technology advances. The use of unmanned aerial vehicles is becoming increasingly regulated by the civil aviation authorities of individual countries.

This may have been the first time an autonomous killer-robot armed with lethal weaponry attacked human beings. As of 2012 the United States Air Force employed 7,494 UAVs – almost one in three USAF aircraft. Due to their wide proliferation, no comprehensive list of UAV systems exists. With the maturing and miniaturization of applicable technologies in the 1980s and 1990s, interest in UAVs grew within the higher echelons of the U.S. military. The U.S. Navy bought the AAI Pioneer UAV that AAI and Malat developed jointly.

What are RPAs

Remotely Piloted Aircraft System or “drones” are now well established in the public consciousness. Safety agency EASA has launched a public consultation on their new regulatory framework, which will enable drone operators greater access to the airspace used by manned aviation. The use of unmanned technology is not entirely new however the availability and affordability have improved significantly. This is beginning to revolutionise aspects of industry previously limited in its use of aerial services due to the high costs involved with running fixed wing and rotary aircraft. SkyGuardian, a new uncrewed and remotely piloted aircraft, has conducted trial flights in the UK this summer to test the platform and how it can safely integrate into UK airspace. You may hold an engineering degree, Aircraft Maintenance Engineer’s License or have gained equivalent experience through your career.

Here, we examine that the RPAS-based thermal approach was efficient to detect Antarctic seals on the coastal regions and count the number of individuals. Based on the size measurements, we expect that it can be applied to distinguish small-sized sub-adults among adults. The captured seal in Figure 4 was estimated to be a sub-adult individual which was resting near the shore.

Knowledge of wider aviation matters and national rules that govern RPAS of all shapes and sizes is desirable. Remote Piloted Aircraft Systems , otherwise known as UAS, is one of the fastest moving, technologically innovative, and generally ground-breaking forces in aviation today. The CAA are currently looking for two RPAS Sector Inspectors to join the RPAS business unit. As a member of the RPAS team you’ll be given the chance to help to craft this burgeoning area of the aviation landscape. While RPAS has maybe been around for a long time, it is relatively new to me.
