When working on an aircraft or aircraft component you should always refer to the relevant aircraft maintenance manual or component manufacturer’s manual. You should also follow your company policy and the requirements of the National Aviation Authority. For health and safety at the workplace, you should follow the rules and guidelines specified by your company, equipment manufacturer, and the National Safety Authority. We aim to provide the best aircraft maintenance practices, technology, and aviation safety tips. RPAS operators are defined as any individual, organization, or enterprise engaged in RPAS operations.
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.
2. Individual Detection and Population Survey
Aerial surveys with manned aircraft require high operating costs, especially for repetitive flights for monitoring purposes, even when investigating a small study area and with a runway within a suitable distance to the study area. This method is adequate for applications with large enough animals, such as medium to large mammals, detectable from relatively higher flight heights than remotely piloted aircraft systems . Remotely piloted aircraft systems have been successfully applied in wildlife monitoring with imaging sensors to improve or to supplement conventional field observations. To effectively utilize this technique, we reviewed previous studies related to wildlife detection with RPAS. First, this study provides an overview of the applications of RPAS for wild animal studies from the perspective of individual detection and population surveys as well as behavioral studies.
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 .

Chrétien L.P., Théau J., Ménard P. Visible and thermal infrared remote sensing for the detection of whitetailed deer using an unmanned aerial system. In wildlife management or conservation, scientists monitor animal populations and make behavior observations from the monitoring with the quantitative information on the status and trends of populations (e.g., ).
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 https://globalcloudteam.com/ 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.
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.

Application of deep-learning methods to bird detection using unmanned aerial vehicle imagery. Anderson K., Gaston K.J. Lightweight unmanned aerial vehicles will revolutionize spatial ecology. 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.
Operations that are conducted outside of VLOS are considered as “beyond VLOS” and where these can be flown in international airspace under IFR. Twitter icon @IshveenaSinghIshveena Singh is a versatile journalist and writer with a passion for drones and location technologies. She has been named as one of the 50 Rising Stars of the geospatial industry for the year 2021 by Geospatial World magazine. The CAA directly or indirectly regulates all aspects of aviation in the UK. In some aspects of aviation it is the primary regulator, in other areas, where the responsibility for regulation has passed to the European Aviation Safety Agency , the CAA acts as EASA’s local office, implementing the regulations.
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.
Unmanned Aerial Vehicles can fly remotely using a controller, tablet, or self-guided and fly autonomously. Drones are ideally suited to capturing aerial shots in photography and cinematography, and are widely used for this purpose. Small drones avoid the need for precise coordination between pilot and cameraman, with the same person taking on both roles. However, big drones with professional cine cameras, there is usually a drone pilot and a camera operator who controls camera angle and lens. For example, the AERIGON cinema drone which is used in film production in big blockbuster movies is operated by 2 people.
Did you get a drone for Christmas?
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.
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.
Though remotely positioned, the remote pilot still has an onboard-the-aircraft view via a camera feed sent to goggles or a monitor. Both fixed-wing and multirotor aircraft can have FPV, which is known for its precise flying and is used frequently in drone racing. The industry has been using the term Unmanned Aerial Vehicle interchangeably with UAS.

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.
There are a variety of possible architectures and considerations in the design, security, and management of the C2 Link. You’ll benefit from an organisation that is passionate about your development in this exciting area. As the UAS sector continues to grow, within the UK and beyond, you’ll be able to drive its development and be a critical part of ensuring that unmanned aircraft operate safely in UK airspace. From assessing initial safety cases through to auditing sophisticated operations on site, you will be a key element in delivering the highest quality of safety-focused regulation to the industry.
Drones, UAVs, UAS, and RPAS; What Are They and Their Differences?
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 rpa accounting use cases guidelines and sticking to applicable laws.
