The Federal Aviation
Administration estimates the bird strike problem costs US aviation
400 million dollars
annually and has resulted in over 219 worldwide deaths since 1988. In the United Kingdom, the
Central Science Laboratory estimates that, worldwide, the cost of birdstrikes to airlines is around
US$1.2 billion annually. This cost includes direct repair cost and lost revenue
opportunities while the damaged aircraft is out of service.(Wikipedia)
Biggest challenge to the
flight crew in encountering the bird strikes id the decision making in terms of
continuing the takeoff/approach or abandoning it. A detailed article guiding
flight crew is provided by SKYBRARY on the subject.
There are instances wherein flight crew on takeoff roll
decide to rotate early to avoid the birds and end up in tailstrike due to early
rotation. Similar instances abound on the final approach, crew carrying out
evasive maneuver and ending up unstabilised on approach, carrying out a
go-around and end up in bird strike at a higher engine RPM and more damage
being entailed to aircraft. For instance, crew decision making has resulted in
tailstrike on landing when hovering between avoidance vis-à-vis landing the
aircraft.
It would appear that it would be prudent at times to
maintain the planned flight path and be decisive rather than a last minute
evasive action during the critical phases of the flight. Briefing before the
takeoff roll and before commencing the approach at airports prone to bird
strikes will help the crew in being better prepared.
Nice post and great awareness. Check out the photos of a 747-400 after landing in Bird strike territory. Actually this airport is closed to aircraft during certain hours because of this threat.

Thanks for your comment and the link to your post earlier on. Great picture the first one, tempting to shoot an approach to Atoll airport!!!!!
