Thousands of airplane bird strikes occur each year, but airports have many safety and conservation measures in place to minimize these potentially damaging and dangerous situations. The majority of bird strikes do not result in substantial damage to the aircraft or danger to the passengers, but conscientious airport officials continually monitor nearby wildlife in order to avoid any potential problems.
Large flocks of birds are hazardous to aircraft, and unfortunately birds enjoy the habitat around many busy airports. Because airports are placed on the fringe of large urban centers, they frequently have large tracts of unused, undeveloped land surrounding them as noise and safety buffers. It is that undeveloped land that is attractive to birds, particularly as suitable habitat shrinks due to urban expansion. Many airports are also near substantial wetlands or drainage ponds – water is a superb noise dampener – which is attractive to migratory waterfowl, gulls and other large birds that can present the most dangerous threats to aircraft.
Both large birds and flocks of smaller birds can be dangerous to aircraft, either by impacting the windscreen or being ingested into the engines. This not only causes significant damage to the plane but can also create hazardous and unsafe flying conditions if critical damage occurs. Because of this, many airports have wildlife control initiatives in place to minimize any interaction between birds and aircraft.
There are three general ways to minimize airplane bird strikes: modifying the birds’ habitat, controlling the birds’ behavior and modifying the aircrafts’ behavior. Airports that have had the most success with minimizing bird strikes have employed all three methods through various techniques.
Modifying the habitat surrounding an airport so it will not appeal to birds is an easy way to encourage wild birds to seek alternative roosting and feeding grounds. Effective measures include:
Several methods can be used to effectively modify birds’ behavior so they will not stay near an airport. These techniques do not harm the birds but encourage them to avoid the airport.
As a last resort, birds may be captured and relocated if they cannot be encouraged to leave the area naturally.
Learning to work with the birds by modifying flight paths and schedules can help minimize bird strikes. While these methods may not be feasible at all airports, they can be used to help the airport work in harmony with the wildlife surrounding it.
Despite the best use of multiple deterrent methods and wildlife management, airplane bird strikes still happen. As airports become busier and schedule flights with greater frequency and alternative habitats continue to shrink, more and more birds will seek refuge near airports, causing potentially dangerous situations. Airports must constantly be on the alert for other fliers in the skies, and as new control and deterrent techniques are developed, it is hoped that bird strikes can continue to be minimized.
