Bird strikes over 50% reduction.
 

From 2012 with 45 aircraft included and data till February 2017 indicated favourably, by an over 50% less bird strikes on modified planes.

Why would you wait till November 2017 when the project ends to make this inexpensive change on all applicable aircraft?


Non changed aircraft 1 bird strike per 1,000 flights


Verses changed aircraft 0.4 bird strike per 1,000 flights.


(If each aircraft did 1 flight a day every day of the year for 5 years that's 82,125 flights or a lot of bird strikes - But I would take 32 over 82 any day)

But I first saw this back around 2000, so I think it is a stolen idea.

Is this what you speak of.

Fugro were using it years ago.

Ah, at last I see what you are talking about. Maybe they should paint windfarm vanes like this too.

Good idea!

This was the other I meant to post of another aircraft.

The number of birdstrikes is reduced because CA$A is administrating the aircraft out of the air. Birds are extremely happy, according to the newspapers. CA$A executives were given a raise for a fabulous safety outcome.

Ascend Charlie, CAsA has reduced the number of birds being killed but not the number per 1,000 flights.


In fact as there are less killed birds, the density of bird numbers has increased. So every flight now hits 272 birds each flight, or roughly 27 birds killed each day over the last 20 years average of permitted flights in Australia!

I hate birds....in fact I hate anything that ****s while flying.

It seems I have been a bit lax in killing them - only 2 in 45 years!

But one of them was a beauty - idling a 222 before engine shutdown, a pigeon flew into the disc and gave a very satisfying POP! as it exploded into 5h1t and feathers.

The other was a Halag (a Galah we caught up to from behind) which was drawn into the rear cabin via the open door. It hit the crewman on the flying boot, and the cockpit filled with what looked like grey ash - just the fine downy feathers. The gud and bluts was smeared all over the crewy's boot and didn't smell very nice.

See the result of a vulture entering a C208 via co-pilot side windscreen and a B200 leading edge.

Been a few others but of only minor damage - resulting in costly inspections or down time.

I took out 5 or 6 homing pigeons on approach to Essendon one time. Does that count?

And before you ask, I know they were homing pigeons because one was hung up in the undercarriage and was banded. We rang the owner to advise that most of his flock wouldn't be coming home that day.

So if you had painted your prop/s, 4 more would had made it home that night!

F@cking pigeons. Rats with wings, complete with the attendant diseases.
