  • a sonic net excludes birds from an Airfield implications for reducing bird strike and crop losses
    Ecological Applications, 2016
    Co-Authors: John P Swaddle, Dana L Moseley, Mark K Hinders, Elizabeth P Smith

    Abstract:

    Collisions between birds and aircraft cause billions of dollars of damages annually to civil, commercial, and military aviation. Yet technology to reduce bird strike is not generally effective, especially over longer time periods. Previous information from our lab indicated that filling an area with acoustic noise, which masks important communication channels for birds, can displace European Starlings (Sturnus vulgaris) from food sources. Here we deployed a spatially controlled noise (termed a “sonic net”), designed to overlap with the frequency range of bird vocalizations, at an Airfield. By conducting point counts, we monitored the presence of birds for four weeks before deployment of our sonic net, and for four weeks during deployment. We found an 82% reduction in bird presence in the sonic net area compared with change in the reference areas. This effect was as strong in the fourth week of exposure as in the first week. We also calculated the potential costs avoided resulting from this exclusion. We propose that spatially controlled acoustic manipulations that mask auditory communication for birds may be an effective long term and fairly benign way of excluding problem birds from areas of socioeconomic importance, such as Airfields, agricultural sites, and commercial properties.

  • Role and function of natural Airfield pavements in the system ensuring air operation safety
    Transportation Overview – Przeglad Komunikacyjny, 2018
    Co-Authors: Mariusz Wesołowski, Krzysztof Blacha, Paweł Iwanowski, Paweł Pietruszewski

    Abstract:

    An important factor impacting the safety of conducted air operations is the appropriate load-bearing condition of natural Airfield pavements. The article contains information on the role and functions to be fulfilled by natural Airfield pavements in various facilities designed for air operations, as well as within individual Airfield functional elements. It touches upon the common issue of insufficient load-bearing capacity of natural pavements, which directly impacts the safety and effectiveness of air operations conducted by military and civilian aircraft. The approach of the authors towards assessing natural Airfield pavements was presented, along with a sample analysis of obtained field test results, as well as the manner of their presentation. Moreover, sample technologies of strengthening in the case of insufficient load-bearing capacity of natural pavements and seasonal agrotechnical and biological treatments necessary to maintain an appropriate load-bearing capacity of natural Airfield pavements, thus, maintaining their continuous operating readiness were presented.

  • The evaluation of Airfield pavements in light of applicable normative documents
    Transportation Overview – Przeglad Komunikacyjny, 2018
    Co-Authors: Mariusz Wesołowski, Paweł Pietruszewski, Adam Poświata, Danuta Kowalewska

    Abstract:

    Airfield pavement evenness is, according to applicable normative documents, one of the basic operating parameters, which characterize each Airfield functional element. Evenness, in fact the lack of it, determines not only comfort of aircraft movement along an Airfield pavement, but also influences the magnitude of the dynamic impacts on the pavement, hence, the safety of air operations. In addition, evenness condition changing as a result of aircraft operation, adverse weather conditions or inappropriate Airfield pavement construction technology leads to deviations from the desired condition in the form of longitudinal and transverse unevenness. Pursuant to the applicable normative requirements, measurements on Airfield facilities can be executed using a planograph or a staff and a wedge. The used measuring devices differ from each other in terms of dimensions and permissible single unevenness. Regular and correct execution of tests is a very important factor improving air operation safety, but also enabling the designation of zones (areas) with quicker pavement degradation. If the obtained measurement data is not sufficiently reliable, they may consequently lead to making incorrect decisions, which can ultimately impact the safety of air operations.

  • Evaluation of the Load-Bearing Capacity of Natural Airfield Pavements by Military Standard No-17-A503:2017
    Research Works of Air Force Institute of Technology, 2018
    Co-Authors: Mariusz Wesołowski, Paweł Pietruszewski, Krzysztof Blacha, Paweł Iwanowski

    Abstract:

    Abstract
    The article presents the evaluation methodology of the load-bearing capacity of natural Airfield pavements in compliance with the Military Standard NO-17-A503:2017. There was addressed the problem frequently occurring on Airfields regarding the insufficient load-bearing capacity of natural pavements, which has a direct impact on the safety of air operations by the military and civil aircraft. The approach of the authors of the standard to the complex evaluation of the load-bearing capacity of natural Airfield pavements on individual Airfield functional elements was described. Moreover, minimum requirements were provided that must be fulfilled to ensure the safety of air operations on natural Airfield pavements.
