Use of drones, or RPAS (Remotely piloted aircraft system) is regulated by its own regulation, known as Regulation for Civilian aircraft A 7-1, regulation for unmanned aircrafts, etc.
There are three operator categories, based on weight and flight. These are described as RO1, RO2, and RO3. We differentiate between drones that are operated in visual line of sight (Visual Line of Sight – VLOS), and beyond line of sight (Beyond Line of Sight – BLOS).
If the flight’s purpose is exclusively for recreation, sport or competition, it is considered as flying model airplanes.
RO stands for Remotely piloted aircraft system organisation.
