Birds versus airplanes
![Page 6: AFM NURUL ALAM GENERAL MANAGER BFCC](https://reader030.vdocuments.mx/reader030/viewer/2022032708/56812bcb550346895d90232c/html5/thumbnails/6.jpg)
Birds Soared the air before Airplanes
The birds may say they have rights of the airspace over planes
![Page 7: AFM NURUL ALAM GENERAL MANAGER BFCC](https://reader030.vdocuments.mx/reader030/viewer/2022032708/56812bcb550346895d90232c/html5/thumbnails/7.jpg)
So, who has the right to airspace? Probably it is the right of the birds to say that airplanes
are a hazard to their life
Many of us have seen the Alfred Hitchcock Movie ‘Birds’. Just imagine………………
We cannot help take action about birds that poise a high risk to aircraft
It is now believed that the total number of fatal bird strike accidents is 54, killing 276 people and destroying 108 aircraft
![Page 8: AFM NURUL ALAM GENERAL MANAGER BFCC](https://reader030.vdocuments.mx/reader030/viewer/2022032708/56812bcb550346895d90232c/html5/thumbnails/8.jpg)
This is what a bird can do to a general aviation aircraft…..
The small, light General Aviation aircraft are very vulnerable to bird hit. Piston engine propeller aircraft can hardly withstand a bird hit in the critical areas
Helicopters are also very vulnerable
![Page 9: AFM NURUL ALAM GENERAL MANAGER BFCC](https://reader030.vdocuments.mx/reader030/viewer/2022032708/56812bcb550346895d90232c/html5/thumbnails/9.jpg)
Birds in Bangladesh Bangladesh is very fertile and fruits and seeds are
found in abundance. The trees provide fruits and perching branches. This support many perching native birds.
Rivers and fresh water lakes provide food for water fouls and fishing birds
Temperate winter attracts migratory birds from the cold north
Sea birds are found in the coastal areas Birds of prey and scavenger birds are also plenty

Point of bird strike on an aircraft
The picture is showing relative percentage of bird strike occurrences on an aircraft

Most vulnerable parts of an aircraft
The engines, the windshield, the wings and the nose areas receive most of the strike
The engines are the most vulnerable For the props and helicopters, propellers and rotors
are the most vulnerable The bird strike may cause fatal accidents due to loss
of power or controllability

When Bird Strike is Likely 85% of bird strikes have occurred below 200 ft
flight altitude Most bird strikes occur in the airport control zone Day time has ten times more probability of bird
strike then night time In Bangladesh winter season bird strikes are more
common than summer

Bird strike is directly related to bird density
Birds in flocks make multiple hits and make avoidance maneuver impossible
High density of birds in or near aerodromes occur when there is attraction for the birds
Birds may be attracted by insects exposed by trimming the meadows, tilling the land, presence of water bodies or availability of food by way of littering

Bird Risk EvaluationHOW? Evaluate aircraft risks Determine bird hazards Categorize relative risk to aircraft types Determine high-risk bird species Plot bird hazard zones around the airfield

Risk Mitigation Relocate most hazardous species by making
the habitat near the airfield un attractive and making another habitat more attractive
Use deterrent to scare other species Keep in mind wildlife conservation and
prevention of cruelty Make the departure and arrival path in such
a way that the

Who will do it In Bangladesh the CAAB performs the bird hazard
mitigation in all airfields. But the number of bird strikes are on the rise
Commercial aircraft operators, the general aviation operators and the military aircraft agencies are suffering from bird hit
CAAB loses nothing, the operators bear the losses from the bird strike. This is a conflict of interest
![Page 18: AFM NURUL ALAM GENERAL MANAGER BFCC](https://reader030.vdocuments.mx/reader030/viewer/2022032708/56812bcb550346895d90232c/html5/thumbnails/18.jpg)
Solution A national forum to discuss bird strike occurrence
should be developed where the acceptable level of risk will be determined and CAAB will be asked to take adequate measures to keep risk below that
The forum must include operators, insurers, the public representatives, the environmentalist and the academicians
