This year, There have been many domestic airports have occurred several unmanned aerial vehicles and other flying objects to invade the airport clearance area, hinder the flight operation of the incident, UAV "black fly" problem intensified.
Unmanned aerial vehicles(UAVs) disorderly easily interfere with the normal operation of military and civilian aircraft, and may even lead to flight accidents, resulting in losses to the state and people's lives and property.
According to the experiment, a weight of 1. 8 kilograms of birds collided with a high-speed flight, the impact is greater than the shells. The general consumption of unmanned aerial vehicles(UAVs) weighs 1.5 kilograms to 150 kilograms, usually made of hard material, if unmanned aerial vehicles (UAVs) collide with high-speed flight aircraft, which may cause serious tragedy of the crash,In addition, it may endanger the safety of personal property on the ground.
Unmanned aerial vehicles (UAVs) rely on wireless signals for data transmission, civil aircraft in flight, control systems, automatic navigation systems, automatic drive systems, landing gear, communications equipment, etc. are susceptible to interference by wireless signals. Aircraft take-off and landing stage is the most vulnerable and threatened, this time if the airport no-fly zone "black fly" UAV, regardless of the occurrence of signal interference or collision events, will cause the aircraft system failure or even out of control, a catastrophic accident, the consequences could be disastrous.
