Beware of Birds and Wildlife
During this Fall Migration

We have all seen it in the movies—that grand exit of the
main character of any typical action flick, the glorious take off of the
courageous leading man in a small, but capable, plane. As the plane ascends, it
flies right through a flock of birds and our leading man flies side-by-side with
our winged friends and eventually soars off into the horizon for a perfect
ending. Yes, we have all seen it, but we know life isn’t like the movies. As
much as Hollywood would like you to believe it, aircraft, no matter how big or
small, are not invulnerable to birds. A bird strike can be very dangerous and
damaging to the aircraft—not to mention the bird.
Wildlife or bird strikes aren’t a new phenomenon. They have
occurred since the beginning of flight. The first ever bird strike was recorded
by Orville Wright on September 7, 1905. His plane struck a bird (believed to be
a red-winged blackbird) over a cornfield near Dayton, Ohio. Although bird
strikes are the most common, they are not the only wildlife threat posed to
aircraft. Pilots must always be cautious of ground animals like deer, rabbits,
bears, and even reptiles, such as alligators or turtles. According to the July
2007 U.S. Department of Agriculture/Federal Aviation Administration report,
Wildlife Strike to Civil Aircraft in the United States 1990-2006, the state of
California has the most bird strikes on record with 6,184 reports since 1990.
New York and Texas reported the most mammal strikes on record with 134 and 147
strikes respectively, and Florida reported 46 reptile strikes. Surprisingly, New
York came in second with 21 reptile strikes. Figures from the FAA Mitigation Web
site show that just in the first five months of 2007 there have been more than
2,200 wildlife strikes reported for civil aircraft in the United States.
The majority of wildlife strikes aren’t reported. However,
since 1990, there have been 83,315 reported wildlife strikes. Of those, 75,731
reports involved civil aircraft and 7,584 reports involved military aircraft at
joint use airports. Wildlife strikes cause an estimated $603 million in damages
to U.S. civil aircraft annually.
Bird strikes are most frequent during migration seasons in
the fall. With the fall migration season approaching, FAA Aviation News wants to
remind you to be extra vigilant. As always preparation and strategic action can
help you mitigate wildlife encounters. Here are some tips to help you avoid
run-ins with birds and other wildlife.
For Bird Encounters (no matter what shape, size, or
number):
Keep all external aircraft lights on. Somehow birds are
able to sense airplane lights and try to avoid them.
Unless close to the ground, pull up and gain altitude
whenever possible around birds. Normally, birds tend to dive down to avoid the
aircraft.
Allow more then the minimum recommended altitude over bird
sanctuaries/refuges/national parks. By having more altitude, the aircraft has a
larger buffer zone, which provides more reaction time. The more reaction time
the pilot has the better the chance to mitigate or avoid an unplanned encounter.
You can find this information along with the locations of sanctuaries at the
U.S. Fish and Wildlife Service <http://www.fws.gov>.
Whenever possible, wear protective eyewear. Even a small
piece of debris can cause a major problem to your eyes.
For other wildlife (i.e. deer, elk, moose, fox, coyote,
rabbits, wild dogs, and bear):
At airports that have active control towers, you should
report any animals spotted in the airport environment. Tower personnel should
pass the information to the airport manager’s office, which should send someone
in a vehicle to chase the animal away.
At non-towered airports, if wildlife is spotted inside the
perimeter, you should contact the fixed based operator (FBO). Someone may be
available to chase the animal from airport boundaries. Also, listen to the radio
at least 10 nautical miles out. There may be someone ahead of you who has
already spotted wildlife. This is also good advice for general situational
awareness.
During night operations, the FBO is still your best source
of information. If no one is available, then carefully and safely announce your
intentions.
-
Before takeoff, taxi down the runway to try and scare
any animals around the runway away.
-
When landing, make a low fly-by down the runway. This
will allow the pilot to see what may be on the runway and, hopefully, scare
away any wildlife grazing along side the runway.
Of course, the best advice is to be cautious. During
migration seasons for our feathered friends, it is wise to be extra vigilant and
cautious. The same applies for our four-legged deer friends, especially during
the fall mating season.
For extra help, you can check out the FAA wildlife
mitigation Web site <http://wildlife-mitigation.tc.faa.gov/public_html/index.html>.
This Web site contains data and reports on wildlife strikes that date as far
back as 1990. Another Web site that will be very helpful to you is the Avian
Hazard Advisory System <http://www.usahas.com>.
This Web site is a risk assessment tool that provides the user with a
standardized measure of bird strike risks for low-level routes.
The United States Bird Avoidance Model <http://www.usahas.com/bam>
is the primary assessment tool for the U.S. Air Force. It is an historical
archive for bird strike information.
The Notices to Airmen (NOTAM) is good way to see where bird
strikes have occurred for that particular day as well as any flight
restrictions. These can be found on the FAA Web site <https://pilotweb.nas.faa.gov/distribution/atcscc.html>.
The information is available to help you navigate your way against bird strikes.
Although we can’t always have the heroic Hollywood
take-off, we can ensure a smooth and safe flight by being mindful and careful of
the wildlife that surrounds us.
