When it comes to autonomous 'driving', the sky is even more suitable than the road. In the air, there are far fewer complicated situations that require software to 'learn' new details – for example, children playing alongside the road, country-specific traffic regulations, one-way streets, or blind intersections.
The cameras and sensor systems used in today's autonomous cars provide a much clearer overview in the sky, where there are no hedges or parked cars to restrict the field of view. And there are no construction zones or tunnels. But the ability to recognize and avoid other flying objects or high buildings must work perfectly. Unlike a car, a drone can evade an obstacle in three dimensions. The autopilot function in commercial airliners proves that air travel is safe without human control. This is guaranteed by comprehensive flight safety systems. If two aircraft are approaching at close range, the Traffic Alert and Collision Avoidance System (TCAS) automatically warns pilots of an impending collision. High-end camera drones can autonomously evade trees, lanterns, and other drones. Multiple sensors provide a 360° view by scanning the immediate environment for possible obstacles and changing direction in case of danger.
