A Chinese software developer has created software that stops hijacked planes from crashing into building. If a plane is hijacked by terrost like on 9/11 this system would take over the control of the plane, with a radar to prevent to plane from crashing into a building.
According to the devlopers this is a safe, effective and low-cost system which can prevent planes from crashing into low altitude constructions or other plane crashes.
This sytem is based on a computer program whose key part is precise map data including the geographical coordinates of skyscrapers, mountains and other potential obstruction on Earth.
Its timely early-warning number can reach 128. According to the developer the system can prevent planes from entering no-fly zone and other restricted spaces.
The system can keep monitoring the position of a plane according to its actual map, indicating the dynamic information of various radar targets. If there is a possible crash object nearby, once the red light is on the equipment can give out sound and light warning to the pilot through radar within two seconds of the plane entering the space. If the pilot fails to receive the instruction radar will automatically intervene and take over the control of the plane.
