Drone regulations are becoming more complex, and there is no easy way for a drone operator to know what is allowed and what is not. There are tens of thousands of rules that apply to drone flying in the United States and even more regulations in Australia. The difficulty is that these rules are all different, and it can be very confusing. It is very helpful to have a way to quickly and easily check the rules and regulations for your specific operation. OpenSky is the easiest way to do this, and it is the best way to fly your drone.

OpenSky is a free app that is available for Android. The app will guide you through the steps to get a certificate of compliance from the FAA or CASA. This will help you to fly your drone in the safest and most legal manner. OpenSky will also notify you about any changes to the planned flight. You can fly safely and legally in controlled airspace, including the busy airspace near major cities.
