Bird strikes cost airlines worldwide more than $1 billion annually. Although most of them are reported to be harmless, we cannot rule out the danger they pose to aircraft.

The ability to take to the skies must still be considered man's greatest achievement. But who would have thought that our winged companions would be the biggest danger in flight, giving rise to the idea of ​​amazing engineering. Bird strikes are by far the most potent threat to aviation worldwide. Witness the infamous engine failure of a US Airways flight that had to land on the Hudson River after 2 geese managed to destroy two of its engines.

A survey conducted by ICAO using data from 91 countries found that airlines encounter an average of 34 birds a day. The loss, if monetized, is more than $1 billion annually. A comforting fact, however, is that almost 92 percent of airstrikes occur without causing any damage.

Most modern engines should be able to feed a bird weighing about 1.8 kg at full power. They must do so at initial climb speed without starting a fire or making it impossible to shut down the engine. In addition to this, at least 50 percent of the electricity must go on for 14 minutes after the strike. This means that even if both engines are hit by large pieces, it can provide a combined thrust on at least one engine that is enough to return to the airport.

Now there are some solutions that may seem obvious. Netting, for example, is the cheapest solution to the bird strike problem. However, a net at the inlet end also poses a major risk. At higher speeds, a 1.8 kg bird strikes with a force of 3,50,000N which damages the net and carries a high risk of entering the engine.

Among the solutions that work to the bird strike problem, a Purdue University study found that darkly painted airplanes attract more birds and thus increase the likelihood of bird strikes. The contrasting light shade blends into the sky and helps the birds fly away from the aircraft.

Also added to the list of solutions is a study done by the Japanese airline ANA which found that aircraft with their eyes drawn to the jet engine's spinner can be an effective way to scare away birds. To this end, 26 Boeing aircraft from the airline's fleet placed samples on the engines. Surprisingly, the method works. The patterned aircraft had only one bird strike compared to 9 for the conventional aircraft during the same period.

The location of the airport also plays a large role in the number of birds that pose a threat to the runways. For example, we can note that the number of bird strikes at Munich Airport is much greater than the number of incidents at London Airport. The main driver that separates the two is location. Munich Airport, which has a fairly large land area, attracts more birds. Meanwhile, London's airport, surrounded by skyscrapers, poses a bit of a problem in this regard.

Speaking of location, food sources near airports can also be a major contributing factor to the number of bird strikes. The crash landing of a Ural Airlines Airbus flight in a cornfield in Moscow was caused by a bird strike. But the blame was soon placed on the illegal dumping of garbage on the outskirts of the airport which attracted more birds. Therefore, any method that discourages nesting and feeding conditions for birds will be an effective way to reduce the number of bird strikes. For example, the grass in and around the airport cannot be very short which will attract more birds. However, the grass should not be too long as it can attract insects which attract small birds.

Another attractive factor for birds is the airport reservoir. It can be covered with netting to keep birds away. Apart from this, there are two ways to keep birds away. Many airports use methods such as decoy drones that look like or imitate predators. Other methods also include pointing lasers and firing flares to keep birds out.

A bird strike—sometimes called a bird strike, bird strike (for Gin), bird hit, or risk of bird strike (bash)—is a collision between an airborne animal (usually a bird or a bat).

And a moving vehicle, usually an aircraft. Power lines, towers and wind turbines (see Bird-skyscraper collision and towerkill).

However, the number of major accidents involving civil aircraft is very low and it is estimated that about 1 accident in a billion (10) causes human death.

The Canada goose ranks as the third most endangered species for aircraft (behind deer and vultures).

About 240 swan-plane collisions occur in the United States each year. 80% of all bird seizures go unreported.

Most accidents occur when a bird (or birds) collides with a windshield or enters the stairwell of a jet plane. That equates to an annual loss of $400 million

In addition to property damage, human-made structures and traffic-bird collisions are contributing factors to the global decline of many bird species.

The International Civil Aviation Organization (ICAO) received 65,139 bird strike reports for 2011–14, and the Federal Aviation Administration counted 177,269 wild strike reports on civil aircraft between 1990 and 2015, a 520% ​​increase from 38,201. The percentage was birds 97%.

However, bird strikes have also been reported at higher altitudes, some at 6,000 to 9,000 meters (20,000 to 30,000 ft) above the ground. Bar-headed geese fly as high as 10,175 meters (33,383 ft) above sea level. An aircraft crashed in Rappel's Vulture at an altitude of 11,300 m (37,100 ft) in Côte d'Ivoire, the shortest bird altitude.

Most bird strikes occur near or at airports (90%, according to ICAO) during take-off, landing and related phases. According to the 2005 FAA Wildlife Hazard Management Manual, less than 8% of strikes occur above 900 m (3,000 ft) and 61% are below 30 m (98 ft).

The point of impact is usually any forward part of the vehicle, such as the leading edge of the wing, nose cone, jet cowling, or nose.

Jet gen insertion is critical due to the gen fan rotation speed and gen design. When a bird hits a fan blade, that blade can be displaced into another blade, causing a cascading failure. Jet gins are particularly vulnerable during the take-off phase when the gin is moving very fast and the aircraft is at low altitude where birds are more common.

The force of the impact on the plane depends on the weight of the animal and the difference in speed and direction at the point of impact. The impact energy increases with the square of the speed difference. Similar to jet aircraft, high-speed collisions can cause extensive vehicle damage and catastrophic failure. A 5 kg (11 lb) bird moving at a relative speed of 275 km/h (171 mph) has about the same energy as a 100 kg (220 lb) bird falling from a height of 15 meters (49 ft) .

However, according to the FAA, only 15% of strikes (ICAO 11%) damage the aircraft.

Explained What Are Bird Strikes And How Dangerous Are They

Bird strikes can damage vehicle components or injure passengers. Flocks of birds are particularly dangerous and can cause multiple blows with associated injuries. Depending on the damage, the aircraft may not recover in time at low altitude or between takeoff and landing.

US Airways Flight 1549 is a classic example of this. The jeans on the Airbus A320 used during that flight were torn by several low-altitude bird strikes. The airport was unable to make a safe landing, forcing a water landing in the Hudson River.

There are identification sites where forensic techniques can be used to identify the species involved. These samples should be taken carefully by trained personnel
