The airport fence is also called an airport security fence or airport perimeter fence. It is a kind of physical barrier that deters and delays any unauthorized access from humans or strikes from wildlife animals.

Many people think the airport fence is just an ordinary fence used to mark the airport&#;s boundary. While actually, the existence of airport fences is critical.
Although we are living in a modernized society full of high-level technique powers, threats of terrorism, attacks on fuel sources, and potential hijacks are still in the way of secure, orderly-run airports all over the world.
Besides, any intrusion of wildlife animals into the airport may result in human injuries and aircraft damage. Just imagine how frightening and dangerous it will be for a pilot flying a multi-million dollar airplane to encounter a deer or coyote suddenly on the runway before take-off.
No matter it&#;s for human sabotage or animal strikes, any breach of an airport perimeter will lead to a severe economic loss and possible damage to the airport&#;s reputation.
As the pandemic turns to an optimistic point, public confidence in flying is increasing steadily. Many people desire to discover new places, experience different cultures and visit friends or relatives that haven&#;t seen for months because of the epidemic.
Under this circumstance, the importance of airport security fences seems to be back to the busy days when there is no pandemic and the flying business is still prosperous.
There are many benefits to using airport security fencing. You may see the main reasons below.
Airport fences are installed around the boundary of airports, outlining airports&#; range clearly, like a notification board indicating this is the place where unauthorized personnel is not permitted to enter.
With airport security technology improved, airport fence systems are not limited to fencing anymore. Cameras, patrols, associated operation systems as well as other advanced technical devices come out to match with the airport fence in succession.
Airports are extremely secure areas. Everyone knows the normal procedures that passengers should follow while entering the airports, never mind the airfield itself. But when security is breached, this will inevitably lead to questions about the intrusions.
A strong and qualified airport fence can deterrent and prevent any intruders successfully. Compared to normal perimeter fences, the airport fence is much higher because of the Y posts, which increases the difficulty of traversing for any intruders.
If you pursue a higher level of security and choose a high-security fence (also known as 358 fences) as the fence panel, it will make any climbing or cutting even harder because of its small mesh openings formed by high density wires.
Many airports have barbed wire fences as standard protection against animals and human intruders coming over the fence. This makes the airport fence strongly fortified.
Airport fences are usually produced from high carbon steel wire with a welding strength greater than 50%. For some curvy wire airport fences, v-bending treatment is applied to the fence panels which largely increases the fences&#; transverse strength. With the combination of factors, airport fences can be used for a long time.
Apart from that, the fence surface is normally pre hot dipped galvanized and then polyester powder coated to make the airport fence resistant to rust and corrosion. That means you don&#;t have to do lots of maintenance in the future.
Airport fences are transparent. Visibility remains one of its greatest benefits, as you can see life scenes of people walking through the airport, and planes taking off and landing, as compared to traditional fencing.
The curvy welded fence is always connected to Y shape posts, with barbed wires and razor wires combined at the fence top to prevent any intruders crossing over.

Just as the name indicates, high security fence is regarded as the highest grade of a security fence for airports.
It is characterized by extra thick wires and small mesh opening which is 3&#; x 0.5&#; in general. The exclusive feature enables high security fences anti-climb and anti-cut. Though it may be more expensive than other airport fencing, the highest security grade really deserve the price.
Barbed wires, razor wires, and other security wires alike are available to be attached to the fence top to increase intrusion difficulty.

If you have ever had a close encounter with wildlife while driving your car &#; glimpsed a deer, coyote or even a large turkey or raccoon at the side of the road &#; or worse, been involved in an accident caused by hitting wildlife &#; then you can understand how frightening and dangerous these situations are for a pilot flying a multi-million dollar airplane. Seeing a deer or coyote on the runway before take-off could cause a string of heart palpitations and sweaty palms!
Interactions between wildlife and aircraft can result in human injuries, even fatalities, along with injuries and fatalities to the animal, and costly repairs to damaged aircraft. The Federal Aviation Administration (FAA) &#; the federal transportation agency with the authority to regulate all aspects of civil aviation, including safety &#; has deemed prevention of wildlife from accessing airports as one of their primary safety concerns.
The first step to resolving any issue is identifying the extent of the problem: how many and what types of wildlife have access to the airport, where they come from, what attracts them to the airport, and how many interactions have occurred at the airport between wildlife and aircraft.
FAA keeps a National Wildlife Strike Database that is available to the public and provides accounting at each airport in the US of the wildlife strikes &#; or moments where a wildlife physically interacted with an aircraft. These strikes are reported annually and include data such as what type of animal, what type of aircraft, time of day, and height of the aircraft at the strike. Airport operations staff keep track of wildlife strikes and provide the data to FAA so that this database can be available for review. It is one important tool to assessing the extent to which wildlife interactions are an issue at an airport.
According to the National Wildlife Strike Database, deer and coyote are the most frequently struck terrestrial mammals. Deer are responsible for a large majority of the mammal strikes that resulted in damage. From to , approximately 291,600 wildlife strikes were reported with civil aircraft in the US.
Airports are also encouraged (or, if the airport is large enough, required), to complete a review of the airport for potential wildlife use and develop a plan for prevention of strikes per the FAA Advisory Circular 150/ - 38&#;Protocol for the Conduct and Review of Wildlife Hazard Site Visits, Wildlife Hazard Assessments and Wildlife Hazard Management Plans. An airport is also required to complete these steps if there has been multiple wildlife strikes over a certain time-period, or there is a single strike that either affects an engine or results in substantial damage that would result in major repair or replacement of the aircraft.
These site reviews, performed by professionals trained in providing this type of review, coupled with the strike data over time, offer a good view of the potential risk at each airport for wildlife strikes.
The next step for an airport is to develop a Wildlife Hazard Management Plan, which identifies the specific actions the airport will take to mitigate the risk of wildlife strikes on or near the airport. Possible steps include:
Airports have a list of wildlife &#;harassment&#; techniques to scare wildlife away from the airport to prevent strikes that includes, some of which are similar to those you may use in your backyard garden &#; shiny or flashy pinwheels or reflective tape, or &#;googly-eyed&#; owl or hawk statues to scare away smaller birds. Loud noises, flares or even air cannons can be shot from a gun or cannon to scare wildlife and birds from the area.
As identified by FAA in (FAA CertAlert No. 16-03, 8/3/) proper fencing is the best way to prevent deer and coyotes from entering aircraft movement areas. This fence, sometimes referred to as a wildlife deterrent fence or wildlife exclusion fence, can be of varying heights and materials, but the FAA recommended design is an 8-foot chain link fence with three strands of barbed wire running along the top positioned so that the barbed wire sections are angled away from the fence to deter animals from climbing over the top. Often, the fence will have a horizontal bottom section called a &#;wildlife skirt&#; that is anchors the bottom edge of the chain-link fabric to the ground and is buried several feet deep to prevent animals from digging under the fence.
More recent FAA guidance was issued in (AC 150/-33C &#; Hazardous Wildlife Attractants on or near Airports https://www.faa.gov/documentLibrary/media/Advisory_Circular/150--33C.pdf) that provides guidance on reducing the attraction of hazardous wildlife both on or near public-use airports. It identifies potential hazardous wildlife attractants, such as stormwater ponds, and agricultural uses like crop fields, so that these can be avoided where possible to further improve safety.
Hoyle Tanner has assisted several of our aviation clients with installing, repair, and maintaining wildlife fences and reducing wildlife attraction.
We assisted the Groton-New London Airport (GON) in Groton, Connecticut with the installation of wildlife fencing along several airport sections. However, because the southern side of the airport faces Long Island Sound, fencing could not be installed around all areas; fences must be offset from runways and taxiways by set distances so that they do not become hazards to aircraft as they take-off and land. In essence, the FAA design criteria for fencing ensures no trade-off between one problem (wildlife) to another (fences becoming hazards). The required offsets at this airport would have placed the fence into deep water within the tidal channel on the southern side, not a permittable action. As a compromise, we worked with airport staff, wildlife biologists, and state and federal permitting agencies to determine the best fencing locations to reduce the spots where wildlife could access the airport to the greatest extent feasible. This solution allowed airport staff to focus observation and deterrence measures in the unfenced areas, which resulted in better vigilance. This airport also installed a varying mesh fence, instead of a chain link, in areas that faced a public park so that the visual impact of the fence would be reduced while still providing an effective deterrent.
We also modified the fence to include a 6&#; opening in the fence bottom at set intervals to allow for the state-listed species of special concern northern diamondback terrapin to enter and exit fenced areas so that their nesting and feeding would not be interrupted.
Fence projects can have different resource challenges in addition to wildlife and wetlands. We assisted the Rhode Island Airport Corporation (RIAC) with design, permitting and construction of a new wildlife fence as well as replacement and repairs to the existing fence at North Central Airport (SFZ) in Smithfield, RI. The project installed approximately 10,000&#; of new perimeter fence with a wildlife skirt to fully enclose the airport and prevent wildlife incursions onto the airport. For this project, due to the location, archaeology was a potential concern that needed to be addressed for permitting. Our team members Public Archaeology Laboratory (PAL) performed a Phase I Archaeological Survey of the proposed fence locations. No cultural materials were found and it was determined that no significant archaeological resources would be affected by the project.
Hoyle Tanner has successfully worked with airport owners to assess wildlife hazards and install deterrent fences across New England in collaboration with FAA and state permitting agencies. Achieving the balance of avoiding or minimizing natural resource impacts while meeting the goals of improving safety for the public, pilots and staff who utilize these airports is an important part of what we can do for clients.
