A New Turf
Artificially turning away wildlife
By Par Carr, President, Airport Surface Technologies
October 2001
While standing in the grassy areas beyond
the runway, I was inspired to consider a synthetic turf as a solution
for replacing grass, a food source for wildlife. Flush with this notion,
I explored the idea with colleagues, and it quickly became clear that
with the right application and underpinnings, an artificial turf could
also be weaved to drain. Using contacts in the artificial turf industry,
where most of the applications are for sports-playing surfaces, I floated
the idea.
In addition to cutting down on bird strikes,
the right weave of fabric could be made to drain immediately; provide
a more stable base for planes during incursions; be designed to create
greater visual clues for pilots; and, cut down on delays in which mud
build-up disables runways and overburdens other runways.
We developed a product called AvTurf. Following
our first-ever installation in Chicago six months ago, AvTurf successfully
passed several tests at Midway Airport, including exposure to jet blast,
the weight of a Boeing 757 airliner, and fire testing. Additionally, emergency
and service vehicles totaling 80,000 pounds traversed on the turf without
any damage. USDA Wildlife Biologist observations show that birds failed
to congregate on the surface as they are accustomed to doing on natural
turf.
Today, we face the challenge of presenting
a simple idea to industry experts expecting something more complex in
nature. We have gone through two years of certification inspections, disaster
drills, accident investigations, and maintenance and safety programs.
Working with professionals in synthetic fiber composition, manufacturing,
and installation, we continue to pool our ideas and experiences to design
and implement what will be the first-ever artificial turf for airports.
Ultimately, the aviation industry can anticipate site-specific decreases
in runway delays due to incursions, bird strikes, and maintenance.
In May, FAA reported that it found AvTurf
acceptable to install in the runway safety areas per 14 CFR Part 139 and
applicable advisory circulars.
