The increased use of drones for civilian applications has presented many countries with regulatory challenges. Such challenges include the need to ensure that drones are operated safely, without harming public and national security, and in a way that would protect areas of national, historical, or natural importance. A variety of the countries surveyed in this report have also made efforts to address concerns regarding the property and privacy rights of landowners or other persons impacted by the operation of drones. International standards to regulate certain aspects of drone operations are currently being considered by the International Civil Aviation Organization (ICAO). In 2011 the ICAO issued a circular titled Unmanned Aircraft Systems (UAS) (CIR328). Serving as a first look at the subject, the circular calls on states to provide comments, “particularly with respect to its application and usefulness,” in an effort to proceed with the development of “the fundamental international regulatory framework through Standards and Recommended Practices (SARPs), with supporting Procedures for Air Navigation Services (PANS) and guidance material, to underpin routine operation of UAS throughout the world in a safe, harmonized and seamless manner comparable to that of manned operations.
