The International Civil Aviation Organisation (ICAO) RPAS team has issued Unmanned Aviation Bulletin (2018/3). This document reports on unmanned aviation operational and regulatory developments. The Bulletin clarifies Key Terms applying to Remotely Piloted Aircraft Systems (RPAS), Unmanned Aircraft Systems (UAS) and related activities.

It would be appreciated if this material could be disseminated widely by readers.

International Civil Aviation Day was established in 1994 as part of ICAO’s 50th anniversary activities. In 1996, pursuant to an ICAO initiative and with the assistance of the Canadian Government, the United Nations General Assembly officially recognized 7 December as International Civil Aviation Day in the UN system.
