But privacy is not the only trouble with drones, they can be a very serious hazard for aircraft pilots. Small drones are generally not visible to the eye of the pilot and they are not detected by onboard surveillance equipment or ATC facilities. Drones can get sucked into an engine or collide with an aircraft which eventually can cause serious damage or even fatalities.
With all these unidentified vehicles in the air, the risk of a mid-air collision increases considerably. To make sure no collisions or problems occur while flying, it is important that all aircrafts are aware of the location, speed and altitude of other aircrafts nearby. With Air Navigation for UAVs, drones are no longer hidden objects in the air and they will be visible to airplane pilots. Drones will be able to transmit their location and be aware of nearby airspaces and waypoints.
