What is bird strike??

A collision between an aerial animal and a man-made
vehicle such as aircraft or spacecraft is known as Bird
Strike.
Some facts about the bird strikes

Bird strikes are a CAP safety mishap.

More than 89000 bird strike reported from 1990-2007 which
is just 20% of actual strikes occurred.

2 pound seagull striking an aircraft with the speed of
140mph exerts a force of 4800lbs on aircraft.

Annual damage of $650 million had been done to just
American civil and fighter crafts and $1.3 billion worldwide.

Over 288 deaths occurred from1988 till date so far.
Important factors need to study
accidents

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
Important factors need to study
accidents

Birds Classification or Taxonomy: Science of the classification of living
organisms. The birds migrate from one place to another, so the
geographic area inhabited by a bird species is called its breeding
range.

Effect of bird weights and density on strikes: Important factors that
decides the damage to be occurred. More damage about to occur in
case of collision with a bird with high density.

Bird behaviour and flying altitude: The bird-flight altitudes vary from 30 to
300 feet above ground level (AGL). 80 percent of bird strikes occur
when aircrafts are below1,000 ft. AGL.

Soaring and Gliding: Soaring and Gliding flight are energy-efficient
behaviours of larger bird species. As a result, soaring birds covers
greater airspace around airports vertically and horizontally giving rise to
more hazards to the aircrafts.
Bird strike accident 26 February,1973

On this date an Learjet 24aircraft departed from Atlanta
(Peach tree DeKalb airport ) strike with brown headed cow
birds which were attracted to nearby trash transfer station .

Intense bird strike caused engine failure eventually leading to
crashing of aircraft on a rooftop of a building.

Accident killed 8 people including 5 passengers , 2 crew
members and 1 person at roof top of the building.

In the response to this accident FAA took serious measures to
clean up the areas around the air strips to avoid attraction for
birds.
Civil aviation and aircraft industry
Industry Growth
 The average growth rate for next 20 years will be 5 %.
 By 2018 world airline fleet is expected to almost
double to over 28,000 aircraft.
Industry Growth
 Canada's airplane business contributed more than $28B to
Gross domestic product and 211,000 occupations to the
Canadian economy in 2015
Industry Growth
 Aviation producing represented near 30% of
aggregate producing part R&D investment's
 More than 20% of aviation assembling movement
(GDP) was committed to R&D, speaking to $1.9B
in 2015
The Canadian aerospace industry
 The lion's share of aviation assembling action
was found in Central Canada.
 The major share of aviation assembling action
was found in Central Canada.
 Western and Atlantic Canada had 60% of
aerospace MRO exercises.
Key findings

Canada's avionic business contributed more than $28B to
GDP and 211,000 occupations to the Canadian economy in
2015

Close to 55% of aviation fares were production network
related, and these developed by half somewhere around
2010 and 2015


Percentage of bird strike on aircraft
 Three-quarters of bird strikes involve the wing or
engines, but they can damage nearly any part of
an airplane.
Cost of aircraft by bird striking

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.
o
Transporting replacement components and mechanics to the site
o
Replacement aircraft
o
Missed connections and re-booking passengers on alternate flights
o
Accommodation and meal costs for repair crews
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.
o Airport emergency response
o Runway closures
o Runway clean-up and repairs
o Flight arrival and departure delays
o Administration of regulatory agencies involved with bird and
wildlife hazards
o Additional fuel used by aircraft during delays
o Airport wildlife-management programs
Wildlife-strike prevention

o
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 wildlifestrike.
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.
o
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.
Wildlife-strike prevention
o
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
o
Avian Radar
Avian radar specifically tracks the movements of birds and give
information data.
o
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.
Wildlife-strike prevention
o
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.
o
Landscape Management
Managing the landscape surrounding the airport limits or removes the
attractiveness of the airport to birds.
o
Lights on aircrafts
The lighting fixtures could offer an in advance warning so the birds can
discover and avoid the aircraft.
