Watched the program.
Their conclusion, frozen or thawed makes no difference to impact.
Strictly a function of mass, velocity, and time of deceleration.


Hmmm, I suspect when dealing with a kg of water it makes a
big difference to the fan blades if that water is frozen
in a single lump.

Maybe in the case of water. But I once talked to an engineer involved
in developing the canopy for the Shorts Tucano and he basically said
the same thing - frozen chicken, thawed chicken, made no difference to
the damage caused.

IIRC he said it was a 4lb chicken that was used as standard.

How often do you strike 4 pounds of bird? Other than ducks and geese, I can't
think of many 4 pound birds you might run a plane into.

Kristan,

Suggest you see:

http://www.birdstrike.org/
http://www.pesthunters.com/BirdStrikeInfo.htm
https://www.avemco.com/briefingroom/birdstrikes.asp
http://www.aphis.usda.gov/ws/nwrc/fi...ky/strike.html

and many other good sources that I found with a Google search (terms: "bird
strikes" +"aviation").

In years past, there were certain seasons when one flew certain military
low-level training routes with extra caution due to bird strike potential.
Low-level hops in areas where 20 lb.-plus carrion birds are common
(Southeastern US, for instance) can be particularly hazardous.

BTW, low frequency is irrelevant if it happens to YOU.

Herring Gulls reach 1.5 kg

Cormorants have been known to be as heavy as 3 kg

Gannets are in the 2-3 kg range

Swans of various types can reach 10 kg

Um, there's lots... I've dodged plenty of hawks and buzzards- big ones over
5 foot wingspan too. It depends what area you fly in I guess.

Buzzards aren't God's smartest creatures either, they don't seem to yield to
anything no matter how big it is. (Even seagulls will give you right of way
if they see you in time.)

They may have the same logic of superior deterrent that seems inherent
to the limited brain of even a tame skunk.

You have to plan for the worst... Delhi is swarming with huge vultures.
Trust me, when one such is lurking on the branch of a nearby tree, one never
feels confident of completing tea on the terrace without incident. Not a 4 lb
bird.....

Birds and Lieutenants scare me more than anything in the air...

I second Jim's words -- seems the MOAs and Restricted Areas have an
abundance of turkey buzzards and re-tailed hawks -- lethal-sized creatures
when they get in your way at high Q.

I've run into four birds in the course of my career, 3 daytime, 1 at night
(at 1500'AGL). Fortunately, they were the smaller varieties -- 2 starlings,
2 undetermined. One of the starlings punched a neat hole the size of my
fist in the leading edge of the intake, went through a couple vertical frame
members and lodged next to a fuel cell. Never knew anything happened 'til a
PC found it post flight in the fuel pits...Class C damage at the time.

Luckiest bird strike story I've ever heard occurred in the sixties at
the AFB I was living on at the time. Pupil pilot on solo night flight
in MB326 was on the approach, a couple of miles out, when he called
the tower saying he was climbing and abandoning the approach as he
thought he'd suffered a birdstrike. Aircraft
seemed fine so he made a second approach and landed safely without
further ado.

On inspection feathers, blood, damage to the wing leading edge and
sand were found. Sand? Next morning they took a chopper and flew
along this character's
flight path to see if they could find the victim. And indeed, about 4
miles before the runway they found a dead ostrich on a sand dune. The
pupil pilot had been misreading his altimeter by a 1000 feet
(apparently fairly easy to do with those old altimeters) and was
virtually on the deck when he thought he was up in the wild blue (or
black, for pedants) still. When he climbed to gain altitude and
assess the damage it is thought he must have barely scraped past a set
of high-tension electrical cables right in front of the dune. Very
lucky little boy, that!

Yeah. I still recall the flight out of Dallas where we took a bird
strike to one of the engines by a turkey buzzard. Big and not very
smart.
