1. COSTS OF WILDLIFE-DAMAGE TO AIRCRAFT
Size and weight of the bird
Aircraft speed
Engine type
Diameter of inlet
Power setting of the engine
Exact location of the strike on the aircraft

2. Three-quarters of bird strikes involve the wing or engines, but they can damage nearly any part of an airplane.

3. COST OF AIRCRAFT BY STRIKING BIRDS
Direct costs
The direct costs refer to those incurred within the repair or replacement of broken parts, and include the actual price of the parts, labor and the overhead cost related with the labor.
Indirect costs
Indirect costs are impacted by the extent of damage to the aircraft, distance from the operator’s closest repair base, size of the airline fleet and the operator’s type of business.
Transporting replacement components and mechanics to the site
Replacement aircraft
Missed connections and re-booking passengers on alternate flights
Accommodation and meal costs for repair crews

4. COST OF AIRCRAFT BY STRIKING BIRDS
Ancillary costs
Ancillary costs square measure are incurred by the airport owner or operator, regulatory authorities, other airport users and emergency-response agencies that must deal with the results of bird or mammal strikes.
Airport emergency response
Runway closures
Runway clean-up and repairs
Flight arrival and departure delays
Administration of regulatory agencies involved with bird and wildlife hazards
Additional fuel used by aircraft during delays
Airport wildlife-management programs

5. WILDLIFE-STRIKE PREVENTION
Airports around the world are using many different bird strike prevention methods. Prevention methods vary widely because no two airports are the same. There are some common method for wildlife-strike. Shooting Birds Shooting not only directly reduces the number of birds on airport properties by killing them, but also scares other birds away with noise and the sight of dying birds. Egg Oiling This method commonly used for Canadian geese, Because Canadian Geese pose such a threat to airplanes. They oiled geese eggs with vegetable oil to prevent hatching. Overhead Netting and Grid Line A promising technology for airports near wetlands is the use of overhead grid line systems. These grids of wires, suspended at least 1.5 meters above the ground, can cover lengths up to 675 meters Avian Radar Avian radar specifically tracks the movements of birds and give information data.

6. WILDLIFE-STRIKE PREVENTION
Predators:
In the past, airports have tried introducing natural predators to scare off flocks of smaller birds. . Trained raptors, such as gyrfalcons, eagles, and peregrine falcons are released by falconers to scare away resident birds.
Drones:
Some airports have experimented with remote controlled planes or drones. Drones act like other predatory birds to scare birds away. It also used by pyrotechnics or noise making devices to scare birds away.
Landscape Management :
Managing the landscape surrounding the airport limits or removes the attractiveness of the airport to birds.
Lights on aircrafts:
The lighting fixtures could offer an in advance warning so the birds can discover and avoid the aircraft.
