Unmanned aircraft, or drones, are a rapidly emerging sector of the aviation industry. There has been limited substantive research, however, into the public perception and acceptance of drones. This paper presents the results from two surveys of the Australian public designed to investigate (a) whether the public perceive drones to be riskier than existing manned aviation, (b) whether the terminology used to describe the technology influences public perception, and (c) what the broader concerns are that may influence public acceptance of the technology. We find that the Australian public currently hold a relatively neutral attitude towards drones. Respondents did not consider the technology to be overly unsafe, risky, beneficial, or threatening. Drones are largely viewed as being of comparable risk to that of existing manned aviation. Further, terminology had a minimal effect on the perception of the risks or acceptability of the technology. The neutral response is likely due to a lack of knowledge about the technology, which was also identified as the most prevalent public concern as opposed to the risks associated with its use. Privacy, military use and misuse (e.g., terrorism) were also significant public concerns. The results suggest that society is yet to form an opinion of drones. As public knowledge increases, the current position is likely to change. Industry communication and media coverage will likely influence the ultimate position adopted by the public, which can be difficult to change once established.

Suppose a homeowner habitually enjoys sunbathing in his or her backyard, protected by a high fence from prying eyes, including those of an adolescent neighbour. In times past such homeowners could be assured that they might go about their activities without a threat to their privacy. However, recent years have seen technological advances in the development of unmanned aerial vehicles (‘UAVs’), also known colloquially as drones, that have allowed them to become more reduced in size, complexity and price. UAVs today include models retailing to the public for less than $350 and with an ease of operation that enables them to serve as mobile platforms for miniature cameras. These machines now mean that for individuals like the posited homeowner’s adolescent neighbour, barriers such as high fences no longer constitute insuperable obstacles to their voyeuristic endeavours. Moreover, ease of access to the internet and video sharing websites provides a ready means of sharing any recordings made with such cameras with a wide audience. Persons in the homeowner’s position might understandably seek some form of redress for such egregious invasions of their privacy. Other than some kind of self-help, what alternative measures may be available?

Este es un estudio sobre la estrategia de guerra estadounidense en Medio Oriente basada en el uso sistemático de drones durante el periodo comprendido entre 2009 y 2013. Se busca explicar de qué manera puede considerarse el uso de este tipo de armamento como una práctica basada en la proyección de poder sin mayor vulnerabilidad. Los casos de Pakistán y Yemen son abordados, ya que evidencian las características de las operaciones selectivas por las que ha abogado el Presidente Obama. El estudio se inscribe dentro del realismo ofensivo, haciendo también referencia a sus limitaciones explicativas. Empero, se afirma que las dinámicas y consecuencias de la utilización de drones son intrínsecas a la necesidad estadounidense de combatir actores no estatales mediante prácticas que garanticen su seguridad y pretensiones hegemónicas a pesar de las implicaciones políticas , legales y sociales en las que puede incurrir.

Los drones sobrevuelan la parcela (previa fijación de sus límites con las coordenadas GPS) y toman fotografías de alta resolución que envían al ordenador central, donde se analizan para localizar malas hierbas y enviar a los tractores robotizados a realizar tratamientos donde haya infestación. A la espera de una legislación europea, el Gobierno Español ha aprobado unas normas provisiona-les que permiten utilizar drones para la realización de trabajos aéreos como son actividades de investigación y desarrollo de tratamientos aéreos, fitosanitarios u otros que supongan esparcir sustancias en el suelo o la atmósfera

El presente trabajo estudia la utilización de drones telecomandados de uso comercial (RPAS) para producir material audiovisual específico de diversas asignaturas de las titulaciones de Ingeniería Civil. Se trata de un equipamiento de alta tecnología y coste relativamente asequible, en torno a 1.300 euros, para producir material audiovisual que hasta ahora únicamente podría ser obtenido empleando medios mucho más limitados (fotografías aéreas y de satélite) o mucho más costosos, tales como vuelos fotográficos específicos. De este modo, se valorará la viabilidad de introducción de una nueva herramienta tecnológica de innovación educativa hasta ahora no empleada en la elaboración de material docente, analizando sus principales ventajas y limitaciones.
