WILDLIFE STRIKE Birds and animals are a serious hazard to aviation. A bird, flock of birds and animals that suddenly rises from a runway or surrounding area may collide with incoming or departingaircraft and cause the aircraft to crash, possibly resulting in the loss of human life. Bird collision with aircraft is commonly known as "bird strike." Damage caused to aircraft usually results from collision of one or more birds with the engines and/or fuselage. Although most bird strikes do not result in crashes, they do involve expensive structural and mechanical damage to aircraft. Most accidents occur when the bird hits the windscreen or is ingested into the engines. The majority of bird collisions occur near or on airports during take-off, landing and associated phases. The point of impact is usually any forward-facing edge of the aircraft such as a wing leading edge, nosecone, jet engine cowling or engine inlet. Engine ingestion is extremely serious due to the rotation speed of the engine fan and engine design. Jet engines are particularly vulnerable during the take-off phase when the engine is turning at a very high speed and the plane is at low altitude where birds are more commonly found. At high altitudes bird strike can cause decompression and injuries among the crew. Birds Affected These include sparrow, blackbird, pigeon, gull, pigeon, goose (geese), kite, pelican, dove, crow, bats, starling and other birds. Animals Affected These include cats, dogs, squirrels, rabbits, rodents, goats, foxes, baboons, hyenas, wild animals.   · What does the term “bird strike” mean? · What is more dangerous: one bird or a flock of birds? · Why is jet engine ingestion dangerous for safety of flight? · What can bird strike cause at high altitudes? What other damage can bird strike cause to an aircraft? · What is done at airports to reduce the wildlife strikes?

Why Aviation Bird-Animal Chaser?

Many types of bird controls have been developed for dealing with bird problems. There are special services that scare birds in the vicinity of aerodromes to reduce the risk of bird strikes. There are security workers and cameras

to check the aerodrome area. It’s important to cut the grass margins and remove trees and rubbish in the vicinity of the aerodrome. Perimeter fence is also a good way to keep the animals away. Some, such as shooting, poisons and fire bombs involve lethal control; however, most people favour methods that exclude or discourage pest birds over killing them. That is why Airport Bird-Animal Chaser is the best electronic airport birds and wildlife chaser worldwide.

The Airport Bird-Animal Chaser is an airport bird and animal control device that causes problem birds and animals to move away from airport and heliport runways using electronic sounds, distress alarm calls, predator attack cries, ultrasonic sound waves, sonic sound waves and PIR Passive infrared detection system.

This type of bird control system has been installed in a number of major airport and heliport runways including USA - San Fransisco; Russia - St. Petersburg; Canada- Vancouver, Calgary; Iceland – Reykjavik; Bulgaria - Sofia Airport; Australia; North Africa; Azerbaijan - Baku Airport; Taiwan; Singapore - Changi Airport; Caribbean; Oman, Dubai; Middle East, etc.

This combined system has a competitive advantage over other airport bird control devices simply because it creates an uncomfortable and disagreeable environment for most bird species and airport wildlife unlike other devices that only tackles bird strikes.

Airport Bird-Animal Chaser not only controls aviation birds but also deters animals in the surrounding areas of the airport. This control measure ensures safe landing of aircraft.

Electronic and natural sounds are emitted at irregular intervals for variable lengths of time, preventing problem birds and animals from growing accustomed to these sounds.

Audio bird deterrent methods use predator cry and distress calls of certain bird species. Whereas, most of the distress calls only work for certain bird species, predator cry sounds usually work with most birds.

This airport bird and animal control product keeps problem birds and animals away from runways and other open airport areas without interfering with radio traffic. This technical airport bird-animal control product ends bird strikes and protects other airport property like signs and lights from bird and animal damage.
