Figure 10
The figure illustrates the different ranges of drone flight operations, categorized as “V L O S flights”, “E V L O S flights”, and “B V L O S flights”. The figure consists of three horizontally aligned zones that represent the varying distances of remote-controlled drone operation based on visual range. Along the bottom of the figure, a labeled horizontal arrow runs from left to right and reads “Range of remote control”, extending across all three flight zones. On the left side of the figure, the first and largest cylindrical area is shown and labeled “V L O S flights”. Within this zone, a human figure labeled “Drone pilot” stands at the center. Adjacent to this section, toward the right, a smaller cylindrical shape labeled “E V L O S flights” is shown. Inside this zone, another human figure is shown and labeled “Additional observer”. A double-headed arrow runs across the bottom between the two cylinders, below the “Drone pilot” and “Additional observer”, and is labeled “Visual range”. This “Additional observer” stands further along the horizontal range axis, between the two cylindrical shapes, representing an observer who extends the pilot’s visual coverage. To the far right, beyond both cylindrical zones, an extended open area labeled “B V L O S flights” is shown, continuing further rightward. A note below the figure reads: “Source(s): Re-illustrated from Stöcker et al. (2017)”.Drone flight ranges
