In the interest of promoting UAV safety and the legal and responsible flying of unmanned multirotor aircraft the CAA have issued CAP (Civil Aviation Publication) 1202 – “You Have Control”. If you’re new to the world of quadcopters, hexacopters, octocopters, helicopters, and fixed wing unmanned aerial vehicles then this guide should serve as a useful reminder of the very basics in terms of operational limits.
You can download a copy direct from the CAA’s website here.
For a more thorough understanding of the CAA rules and regulations regarding the operation of unmanned aircraft in the UK’s airspace you will also need to study sections 166 and 167 of CAP 393 (Air Navigation: The Order and the Regulations), and CAP 722, both of which can be retrieved from the CAA’s website. It’s recommended that you check the site for the latest copy on a frequent basis and register for the free subscription service which will inform you of any changes to the regulations for unmanned aviation, UAS, and drones generally.
