We still remember that American Airlines Flight 1549 was forced to land on the Hudson River after being hit by a bird strike. The plane that hit the plane was a group of Canadian geese. Because the birds are very different in visual stimuli from humans. It is therefore difficult to prevent them from flying into the route by conventional methods, but now science brings us a solution, that is, LED lights.
Researchers at the US Department of Agriculture, Indiana State University and Purdue University have just published a paper that they are looking for ways to scare off birds that are close to the aircraft.
The research team sent three radio-controlled aircraft, one of which was a normal aircraft model, one disguised as a predator, and the last with flashing alternating pulsed LED lights at 2 Hz.
The results show that when the lights are flashing, the birds will quickly notice the aircraft and avoid it, which is better than pretending to be a predator.
It seems that only a simple thing like LED can reduce the annual loss of billions of dollars in the aviation industry, and maybe the airline will accept it in the future.
