“…To achieve an efficient-and, for further research, real-time capable-implementation of the algorithm, filtering of actually threatening birds for the effective, run-time-intense trajectory comparison is highly relevant. Therefore, a two-step approach, which has been developed in earlier research, was chosen [8]. First, relevant birds are filtered in the socalled broad phase.…”

“…The evaluation of these factors is the scope of this study. It builds on a previous analysis which researched the influence on traffic flows and the hypothetical maximum safety potential of such a system, independent of the effectiveness of any predicting algorithm [8]. For this purpose, perfect predictability of bird movement was assumed.…”

“…In the idealized setting of the study, over 99% of strikes were prevented in the performed Monte Carlo simulations. Runway capacity could be maintained and the delays resulting from the preventive actions lay within reasonable limits for most scenarios [8]. In the current study, the next step is taken by abandoning the assumption of perfect predictability, and replacing it with a prediction logic.…”

Bird strike prevention in civil aviation has traditionally focused on the airport perimeter. Since the risk of especially damaging bird strikes outside the airport boundaries is rising, this paper investigates the safety potential of operational bird strike prevention involving pilots and controllers. In such a concept, controllers would be equipped with a bird strike advisory system, allowing them to delay departures which are most vulnerable to the consequences of bird strikes in case of high bird strike risk. An initial study has shown the strong potential of the concept to prevent bird strikes in case of perfect bird movement prediction. This paper takes the research to the next level by taking into account the limited predictability of bird tracks. As such, the collision avoidance algorithm is extended to a bird strike risk algorithm. The risk of bird strikes is calculated for birds expected to cross the extended runway center line and to cause aircraft damage upon impact. By specifically targeting these birds and excluding birds lingering on the runway which are taken care of by the local wildlife control, capacity reductions should be limited, and the implementation remain feasible. The extrapolation of bird tracks is performed by simple linear regression based on the bird positions known at the intended take-off times. To calculate the probability of collision, uncertainties resulting from variability in bird velocity and track are included. The study demonstrates the necessity to limit alerts to potentially damaging strikes with birds crossing the extended runway center line to keep the imposed delays tolerable for airports operating at their capacity limits. It is shown that predicting bird movements based on simple linear regression without considering individual bird behavior is insufficient to achieve a safety-effect. Hence, in-depth studies of multi-year bird data to develop bird behavior models and reliable predictions are recommended for future research. This is expected to facilitate the implementation of a bird strike advisory system satisfying both safety and capacity aspects.

Statistical data on aircraft collisions with birds of prey (Falconiformes and Accipitriformes) are analyzed. The basis of the analysis was the results of study at the Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences (IPEE RAS). The reasons and factors attracting birds of prey to airfields are considered. In the period from 2005 to 2022, seven species of birds of prey involved in 29 collisions with aircraft were identified. The largest number of birdstrikes occur with the Common Kestrel Falco tinnunculus and the common buzzard Common Buzzard Buteo buteo. Most collisions occur at the airport or in its vicinity; strikes occur 4.3 times more often during take-off than during landing. Primarily the engine or wing structure is damaged by collisions with raptor birds. Recommendations are given to control bird behavior to minimize strikes with birds of prey at the airfield.

Aproximación teórica a la definición del concepto de sitio atractivo de avifauna fuera del aeropuerto

La mayor parte de los impactos entre aeronaves y fauna ocurre dentro de los aeropuertos; sin embargo, casi la mitad de los impactos con daño se presenta fuera de estos. Por ello, los programas de peligro aviario deben considerar seriamente las zonas externas a los aeropuertos para lograr una gestión completa del riesgo de impacto. Pero estos programas presentan varias limitaciones para su implementación en el exterior, entre estas la falta de una definición precisa de la noción de hábitat atrayente de fauna fuera del aeropuerto, lo que reduce el concepto a un nivel intuitivo que obstaculiza la optimización del sistema de análisis del riesgo. Esto último impide identificar claramente las zonas que se han de evaluar y, posteriormente, manejar con la modificación de hábitats. Para abordar este problema, se propone el concepto de sitio atractivo de avifauna (SAA), definido como el lugar en el área de influencia aeroportuaria que presente, confirmada y regularmente, una bandada de al menos cincuenta aves voladoras y riesgosas. Dicha propuesta puede significar un importante adelanto para la seguridad aérea desde una gestión eficiente del riesgo de impacto por fauna fuera del aeropuerto.
