Where I am, in my city, surrounded by heliports and 2 airports. The graph is from the DroneBuddy app. With the NEO and not exceeding 60 m in height and not invading any red area (FRZ) I am not worried, but with another drone I have (AIR 2S) I already have to ask for authorization from the competent agency that controls our airspace (ANAC/DECEA)
