DRONE ENABLE, ICAO's Fourth Unmanned Aircraft Systems Industry Symposium (DRONE ENABLE/4) Date: 13 - 15 April 2021 Location: Rio De Janeiro, Brazil Venue: Windsor Barra Hotel Registration: Update 29 May 2020 Due to the ongoing impacts of travel restrictions, public health concerns of large gatherings and uncertainty in the short to medium term caused by COVID-19, ICAO has made the difficult decision to postpone the Fourth DRONE ENABLE Symposium, which was originally scheduled for 9 to 11 September 2020 in Rio de Janeiro, Brazil. The symposium, renamed DRONE ENABLE 2021, will now be held from 13 to 15 April 2021, with the location remaining Rio de Janeiro. As it is understood that the current COVID-19 situation may have negatively impacted the ability of States, organizations and individuals to respond to this year's RFI, ICAO has extended the submission deadline to 25 September 2020. Those that have already submitted responses are welcome to update their original submission and those that were unable to meet the original timeline are invited to provide a submission by the revised deadline. Please feel free to contact ICAO at DRONEENABLE@icao.int should you have any questions. The International Civil Aviation Organization (ICAO) Fourth DRONE ENABLE Symposium will be convened from 13 to 15 April 2021 in Rio de Janeiro, Brazil. The theme of the symposium is "Addressing Tomorrow's Challenges Today". The symposium will bring together key stakeholders from industry, academia, government and international organizations in the unmanned aviation sector to exchange best practices, lessons learned, research material and challenges related to the introduction of unmanned aircraft systems (UAS) and UAS traffic management (UTM). On the second day of the symposium, panel speakers will be featured from those who comprehensively responded to the problem statement in our revised Request For Information (RFI) regarding the advancement of the ICAO UTM framework. The symposium will showcase the breadth of existing technologies, ongoing research and development, as well as describe commercial and non-commercial activities in this rapidly evolving sector of the aviation industry. The symposium will provide participants with valuable networking opportunities. We encourage you to take advantage of the wide range of sponsorship and exhibition opportunities available to showcase your State, organization, or company. Please note that the symposium will be held in English. For further information please contact RPASEvents@icao.int.
