Foreign Object Debris in Aviation: Risks, Current Mitigation Strategies, and Technological Innovations

Foreign Object Debris (FOD) presents a significant threat to aviation safety, impacting both civilian and military air operations worldwide. FOD refers to any object, whether natural or man-made, that poses a risk of damage to aircraft through ingestion, collision, or interference during ground operations or flight. This paper examines the critical impact of FOD on aircraft performance, operational costs, and passenger safety, highlighting notable incidents where FOD was a contributing factor to accidents and maintenance challenges. This study highlights the current, well-established preventive measures such as regular runway inspections, advanced FOD detection systems, strict personnel protocols, and improved material management practices. Key strategies for mitigation are discussed, which emphasize the need for novel approaches and improvements through emerging technologies to contribute to the evolving landscape of aviation safety. Furthermore, the importance of encouraging a strong safety culture among airport authorities, ground crews, and airline operators is reinforced as a critical element in minimizing FOD-related risks. One of the key contributions of this study is its exploration of identifying latent FOD hazards through cutting-edge technological innovations. For example, paved airfield surfaces dislodging and being ingested into engines and propellers are common risks. Additionally, bird repellents have not been effective in removing bird nests inside hangars, posing a persistent hazard. Has there been an effective method yet to prevent bird strikes, particularly during landing and takeoff? Adopting advanced technologies can significantly enhance the aviation industry’s ability to prevent FOD events, ensuring safer skies and more efficient airport operations.
