Analysis of Risk-Based Operational Bird Strike Prevention

Abstract

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.

Pengaruh Motivasi Kerja dan Disiplin Kerja terhadap Kinerja Karyawan Airport Operation Control Center (AOCC) di Bandar Udara Internasional Soekarno - Hatta Cengkareng

“…Jika pimpinan ceroboh, tidak tegas, dan kurang memperhatikan kondisi karyawan, maka dampak kinerja karyawan akan menurun. Hal ini bisa terjadi karena karyawan tersebut merasa kurang dihargai oleh pimpinannya (Evler, 2021b(Evler, , 2021aMetz, 2021;Pilon, 2021;Watkins, 2021).…”

Bird Detection and Overall Bird Situational Awareness at Airports

“…Bird strike prevention at airports is characterized by a comprehensive and specialized approach and is a constant concern (Metz et al, 2021). In the future, airports should e ciently integrate advanced technologies from various elds to carry out accurate bird strike prevention and control based on the reliable bird data obtained.…”

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

“…Por otra parte, algunas de las metodologías formales más relevantes sobre el riesgo por fauna fuera del aeropuerto (Metz et al, 2021a(Metz et al, , 2021bShao et al, 2020aShao et al, , 2020bCoccon et al, 2015;Gerringer et al, 2016) no han definido objetivamente su unidad de estudio como elemento espacial de riesgo en función de las aves, es decir, los hábitats atrayentes de fauna, sino que lo han minimizado a conceptos ecogeográficos ajenos como cuadrículas de referencia, áreas geométricas, usos del suelo, coberturas vegetales o hábitats puntuales. Esto último, sumado a sus matemáticas, tecnologías y logísticas robustas, puede contribuir a que estas propuestas gocen de poca aceptación universal porque les confiere un carácter científico muy duro que hace que el proceso sea inevitablemente complicado y merme su practicidad para la implementación regular en los aeropuertos.…”
