High altitude, high speed bird strikes

Mon Sep 09, 2019 4:12 pm

Apparently Qantas had one Friday.

https://simpleflying.com/qantas-airbus-a330-vs-eagle/

I remember years ago a KLM M11 taking one even higher.

Storks & eagles are notorious. Up to 20,000 to 30,000 ft :crazy:

They should forbid them hanging around there, a bad attitude.

1) Surely, you mean high altitude? You may want to correct that in the title
2) Is there something in that photo that I am missing? No birds as far as I can see :ugeek:

The article says 4,000 feet. That's not high "altitude".

I think perhaps the birds had both the high speed and the bad attitude?

Clearly the bird should have had his ADS-B on....How else did it expect TCAS to work...

The article is wrong, the aircraft took off runway 6, the eagle (a blue and gold one perhaps) was hit directly after take off, the aircraft levelled off originally at 2750 feet prior to returning to PER and climbed to 4000 feet briefly

Years ago I hit a flock of something around 18000’ going 320 knots. When I did the post-flight walk around, we had hits on both wings, both sides of the horizontal stab and ingestion in both motors.

Oh and that smell after the ingestion...

This comes up here now and again, usually after a notable birdstrike incident ... this is interesting reading: https://www.historynet.com/when-birds-strike.htm

The record for the highest bird strike is 37,000 feet, in an incident on November 29, 1973, during a commercial flight over Abijan, Ivory Coast, in West Africa. Although the airliner lost one engine, it landed safely. The bird was later identified as a Ruppell’s griffon vulture, thought to be the highest-flying bird in the world.

Check the record for the highest birdstrike. You'll be surprised.

Have you seen how Kessje usually has a fly in his diagrams like when he is showing possible NMA designs? I wish I were able to superimpose an image of a fly careening off the wing in his original picture.

I don’t know what a Southwest 737 flying over Las Vegas has to do with a Qantas A330 bird strike in Perth.

Guys, obviously those pylons are red because they're covered in bird blood. ;)

My question is, what the hell is a bird doing at such a high altitude?? :wideeyed:

Any ornithologists here?

not otnitologist, but my suggestion is

- that vultures using chain recon, i.e. some birds can fly higher and look at buddies at low level awaiting they find a food.
- wiki says they using ultraviolet for killing cadaveric bacteria on them, so they may fly high for this reason.

also i think this one just may asleep/pass out by low oxygen and still climbing in upwars flow.

The foto is taking at 20.000ft to give an impression of the attitude. Even eagle eyes can't see much happening on the ground.

Temperatures e.g. 30C at ground level can easily be minus 20C at 30.000ft and oxigen is low. Not a to place be..

The birds have a specialized variant of the hemoglobin alphaD subunit; this protein has a great affinity for oxygen, which allows the species to absorb oxygen efficiently despite the low partial pressure in the upper troposphere


also, i remember Willi Weber (M.Schumacher manager) private jet got bird strike on the half of route over Himalayas. can find link now (10+ y passed) but radome cupola was almost completely dent
