Recently, a person playing with a laser pen encountered a problem. At present, laser damage has become a common threat to the safety of international civil aviation and has been highly valued by all parties. The author believes that effective measures to prevent the recurrence of similar events can only be effective under the following circumstances: when the flight from Qingdao to Dalian reaches 3100, a bright green beam shoots at the aircraft from the ground and continues to move on the fuselage. When light passes through the eyes, vision is immediately stimulated and distorted. Blindness lasted about a minute. These scenes are the reporter's last personal experience. According to the survey, the high-power laser pen has become an uncontrolled cab. More and more people use it as a toy to accidentally radiate pedestrians and even fly at high altitude. He is from Missouri and Kansas and is accused of using a Laser pointer to illuminate a helicopter over his home. It's harder than flying, but unfortunately, the helicopter is a police helicopter. His camera recorded the laser and the location of the suspect. 1000 meters is illegal. Only a few seconds after hitting the pilot directly in the eye could he suffer temporary visual damage and cause the plane to crash. Contact with other parts of the aircraft shall not cause injury. The laser pen uses a button. The battery power on the button is too low to be damaged by laser equipment (such as range, viewfinder, communication, night vision, etc.).
In addition to the effect of direct exposure to laser on pilots' vision, laser pens also pose another indirect threat - night or other low visibility conditions. Pilots usually rely on the airport's auxiliary landing lights to land. However, if the airport lighting and other high brightness light sources (such as laser connectors) illuminate the same area, it is easy to confuse and interfere with the pilot's judgment. This will have serious consequences for the landing of the aircraft.
