... 147 People Have Died in
U.S. Since 1990.

Stephen Becker couldn't have picked a better morning to fly than April 22.
Clear, a gentle wind, temperature in the mid-70s.
Becker, an economic consultant who flies a single-engine Cirrus SR22, took
off from Austin-Bergstrom International Airport's east runway. Less than a
minute later, flying about 1,100 feet over one of the two landfills south
of the airport, Becker saw the two turkey vultures whoosh right to left
just in front of the propeller on his airplane's nose. His immediate
reaction was relief at the near miss.
Stephen Becker thought his Cirrus SR22 was safe after two vultures whipped
across his path in April, but one crashed into the left wing.
Then one of the birds smashed into the end of the left wing. Though a
turkey vulture weighs at most 5 pounds, the impact shivered the plane and
twisted it to the left. After a quick obscenity, Becker regained control
and reported that the plane was in distress.
Given carte blanche to land on any runway, Becker and his wife, Emilie,
pulled to a stop on the west runway minutes later. The outward 2 feet of
the left wing were a crumpled mess.
"It was all smashed, with pieces of it flapping up and down," Becker said a
couple of weeks after the incident. The plane is still grounded awaiting
repair. "My experience is there is general bird activity around Austin. I
have seen birds and had to dodge birds all around this airport, both north
and south."
Reports of collisions between airplanes and birds, both locally and
nationwide, have been increasing in recent years. Pilots of civilian
aircraft reported 57,702 such collisions in the United States between 1990
and 2004, an average of about 3,850 a year. In 2004, there were 6,360
reported bird strikes, according to Federal Aviation Administration
statistics.
Austin-Bergstrom, meanwhile, has gone from 14 reported bird strikes in
2000, its first full year of operation, to 46 in 2005. The airport has
about 80,000 takeoffs and landings in a year.
Just seven of the strikes since May 1999 have been with what are classified
as large birds, such as the luckless vulture that crossed paths with
Becker. At least 70 percent of the 202 collisions since the airport's
opening involved airliners or large cargo planes. None of the strikes have
caused crashes or injuries.
But birds can and do bring down planes, occasionally even large ones.
According to a recent report from the FAA, since 1990 there have been more
than 120 aircraft taken down in the United States by bird strikes, killing
at least 147 people. In 1995, for example, a U.S. Air Force E-3 AWACS plane
taking off from Elmendorf Air Force Base in Anchorage hit about three dozen
geese and crashed, killing all 24 on board.
Experts point to several possible causes for the rise in bird strikes: more
planes in the sky, increasing bird populations because of greater
protections for migratory species, and a greater percentage of pilots
reporting minor incidents with little damage (to the plane, at least).
Concern has increased to the point that the FAA, its Canadian counterpart
Transport Canada, and the U.S. Air Force last year released a plan to
develop a North American Bird Strike Advisory System to better warn pilots
about the presence or likelihood of birds near airports. And in Central
Texas, general aviation pilots in particular have been pushing for measures
to limit their chances of hitting birds. About 10 pilots showed up this
week at a meeting of the Airport Advisory Commission to ask for help with
the problem.
"We want the landfills closed," said Jay Carpenter, president of the Texas
Aviation Association, which is made up of private plane owners. Carpenter
has video from four weekends in October 2004 showing up to 10 turkey
vultures hanging out at Travis County Landfill about a mile south of the
airport's west runway. "Getting rid of those landfills may not eliminate
the bird strikes in the area. I doubt it will. But it would substantially
reduce the risk."
No, it wouldn't, said Fletcher Kelly, a consulting engineer for IESI, owner
of that landfill. That landfill opened in 2000, after Austin-Bergstrom
opened, and has never accepted household garbage with the sort of organic,
rotting goodies that would attract turkey vultures, Kelly said. Instead,
the landfill takes in only construction and demolition debris. The City of
Austin landfill just east of the IESI facility, which opened in the 1950s
and for decades accepted organic waste, no longer does.
Yes, the IESI landfill has some birds, including vultures, that show up to
"loaf," Kelly said, waiting for the next bit of carrion to turn up within
nose-shot. The water and woods of Onion Creek lie just north of the
landfill, Kelly pointed out, and Burleson Road, which runs between the
creek and the airport, is a steady source of roadkill.
On two visits to the landfill over the past couple of weeks, the Statesman
observed just two turkey vultures at the landfills. But both days were hot
and still, conditions that Cliff Shackleford, an ornithologist with the
Texas Parks and Wildlife Department, said renders vultures and other birds
inactive. And by early May, most of the vultures that migrate from northern
states to Mexico have already moved through Austin, leaving us with only
our full-time resident vultures.
"Every day can be different," Shackleford said. He did say, however, that
turkey vultures have a powerful sense of smell. Even one discarded
sandwich, given time to rot, can attract them, he said.
But Austin-Bergstrom's statistics support the idea that birds are the
problem, not the landfills. Of the 202 strikes reported since 1999, 22 were
south of the east runway (where Becker took off) and 34 were south of the
west runway (where he and the vulture hit). That means 72 percent of the
strikes occurred north of the airport (miles from the landfills), where
there are homes, businesses and, not coincidentally, the Colorado River.
Bodies of water, of course, attract birds, something that Austin-Bergstrom
officials work to prevent on the 4,400-acre airport property. The airport
has taken a number of measures to ward off birds and other wildlife,
festooning roosting spots with plastic obstacles and wire netting, putting
miniature speakers at various spots that play recordings of birds in
distress and predator calls, and shooting propane cannons to scare birds
away.
Becker, for his part, is sufficiently spooked by his encounter with the
vulture that if he has to head west on a future trip, he'll ask the tower
if he can make a loop to the east and north and then back to the west to
avoid flying over the landfills.
"It's not something I want to do again," Becker said.
On the other hand, Becker notes that a friend of his who has a private jet
had to dodge a whole flock of turkey vultures about a week after his
collision. He was flying at 2,500 feet more than four miles north of the
airport.

AIRMEN ENSURE B-52s, KC-135s AVOID BIRD STRIKES
Defend America 4/27/06 Deployed
airmen monitor the threat to aircraft from bird strikes, the B-52s and KC-135s can complete their missions. By U.S.
Air
Force Master Sgt. Scott King 40th Air Expeditionary Group OPERATION ENDURING FREEDOM, April 27, 2006 - The team
of four
airmen works to save lives, aircraft and money; they usually work behind the scenes, often unnoticed, until something goes wrong. They
are vital to the mission of this forward operating location serving Operation Enduring Freedom, and are responsible for the Bird
Aircraft Strike Hazard, or BASH, program. "With minimal resources available, especially at a deployed location, we
cannot afford to lose one aircraft to a bird strike." U.S. Air Force Tech. Sgt. Roy Ollie. The 40th Air Expeditionary
Group safety office executes the BASH program 24/7 monitoring, evaluating, and where needed, eliminating the threat so that the B-52s
and KC-135s based here can complete their combat missions. The primary threats to bombers and refuelers launched and
recovered from here are wimbrels, mynahs and egrets. "For an effective BASH program we need to ensure aircraft are safe to takeoff and
land without the threat of a bird strike," said U.S. Air Force Tech. Sgt. Roy Ollie, flight safety noncommissioned officer. "With
minimal resources available, especially at a deployed location, we cannot afford to lose one aircraft to a bird strike." The B-52s launched from here provide close air support for U.S. and coalition forces on the ground in Afghanistan. The
KC-135s launched here provide the airborne refueling capability to ensure the B-52s can complete their combat missions. The safety office uses a four-pronged approach to decrease the threat of further aircraft/bird strikes. There are six
cannons on the airfield. The control tower or the safety office sets them off when needed to scare the birds out of the area. The safety
office also uses pyrotechnic guns to scare birds away. Another approach is "pushing" or "directing" birds out of the area with the
safety vehicle by approaching them and slamming doors, honking horns etc. The last approach is depredation or eliminating the birds with
a shotgun. The cost of a bird strike here can be deadly or, at a minimum, can create mission no-go. "Depending on where
the strike occurs, it could cause an engine failure that leads to a loss of thrust during takeoff where the crew and aircraft would be
lost," Ollie said. "Another possibility is losing vital instruments or flight control systems because an engine driven
generator or hydraulic pump isn't functioning also resulting in a catastrophic mishap." Another factor to consider if a
bird struck a plane is the non-mission capable status while engines are being replaced. Both the B-52 and KC-135 could be down for 24
hours or more, thus hampering our mission here of taking the aerial fight to the terrorists in Afghanistan and helping the people of
that country." B-52 pilots here know how important this often unseen program is to their mission. "As a
commander of a combat squadron, a solid BASH program offers my organizations two important benefits," said U.S. Air Force Lt. Col. Mark
Maryak, 20th Expeditionary Bomb Squadron commander. "First, avoiding bird strikes offers immediate benefits for the crews returning from
extremely long duration sorties. If they were to encounter a bird strike while approaching the field, they would have to hold and
accomplish a, time consuming, controllability check. Secondly, avoiding bird strikes keeps our B-52 fleet healthy. Because the
maintainers do not have to spend time inspecting and fixing bird strike-related problems, they can prepare the our bombers for their
next 'in country' sortie in minimum time - taking the fight to the enemy."

GREEN LASER BEAMS COULD BEAT DEADLY BIRD THREAT AT AIRPORTS Search ASIA Travel Tips .com, 23 March 2006
Laser beams sweeping airport runways to scare away birds could help civil aviation authorities beat a big threat to aircraft safety at take off and landing.
Around 50,000 bird strikes on civil aviation aircraft are recorded worldwide every year, with 11% affecting the flight and some of the incidents leading to fatal crashes.
The threat is greatest when birds crash into windscreens or are sucked into jet engines, but a French idea to be unveiled in the Middle East later this year could help solve the problem.
Lord Ingénierie has developed an automatic laser system to tackle the threat posed by birds to aircraft, and the TOM500 will be introduced at the Airport Build & Supply Exhibition in Dubai June.
The system uses a green laser beam, as research by ornithologists from the French civil aviation authority (DGAC) found that birds’ eyes are more sensitive to green light, and is so far-reaching that a single unit can cover a runway up to two kilometres long.
Birds flying near runways and interfering with aeroplanes’ take-off and landing are a potentially deadly problem for airports. According to figures released by the International Civil Aviation Organisation (ICAO) in 2003, air accidents caused by bird strikes had up until then resulted in the loss of 400 lives and the destruction of 420 aircraft. Ninety per cent of all birdstrikes happen at or around airports.
Civil aviation officials and other visitors to the Airport Build & Supply Exhibition, will be able to see the laser in action as technicians from Lord Ingénierie will give demonstrations using a smaller hand-held version.
Project manager Alain Danielou believes the Middle East will become an important market for the new TOM500 system and says the exhibition is vital for securing business in the region, “This is brand new technology and totally different to traditional methods of dealing with birds at airports such as acoustic and pyrotechnic systems. The Dubai exhibition is a great opportunity to convince visitors of the TOM500’s benefits and make contact with potential customers. Many major airports in the Middle East are near the coast and airports close to the sea tend to have particular problems with birds.”
Lord Ingénierie took around one-and-a-half years to develop the TOM500 system after being awarded the contract by DGAC. The system has been on test for more than a year at Montpellier Airport in France. During this time there have been no collisions with birds or any sign that birds are becoming accustomed to the laser. The product went on the market in 2005 and the company received their first order in January this year to install it at another French airport.
The TOM500 laser automatically begins scanning runways at regular intervals on pre-programmed paths once light levels go below a certain point. Birds are frightened away by the stick-like effect of the laser. The beam is close to the ground, causes no visual problems for pilots and is harmless to eyes and skin.
Danielou said, “The problem that birds pose to aircraft at night has until recently been underestimated because of the assumption that birds are roosting. However birds are easily disturbed and according to the ICAO forty per cent of bird collisions happen at night. The TOM500 is particularly useful in the Middle East as, for much of the year, the light fades at around 6pm and there are 12 hours of darkness. We hope to find a regional distributor for the product at the Airport Build & Supply Exhibition.”
Taking place from June 5 – 7, 2006 at Airport Expo Dubai, the Airport Build & Supply Exhibition is expected to attract more than 400 of the world’s leading airport and aviation suppliers, who are aiming to capitalise on more than US$ 40 billion worth of airport developments currently taking place across the Middle East. |
