Which term describes debris that could pose a risk on runways and taxiways?

The term that describes debris posing a risk on runways and taxiways is Foreign Object Debris, commonly referred to as FOD. FOD encompasses all types of objects found on airport surfaces that can interfere with aircraft operations, including items like loose stones, equipment parts, or any materials that could potentially be strike hazards during takeoff, landing, or taxiing.

Understanding the significance of FOD is critical for airport safety management. It highlights the need for regular inspections and clean-up procedures to keep airfield surfaces clear, thus preventing potential aircraft damage, accidents, or disruptions in operations. The identification and removal of such debris is an essential aspect of ensuring safe and efficient aircraft movements.

The other terms listed relate to different aspects of airport operations: Towbarless Tow Vehicle pertains to a type of ground vehicle used for towing aircraft, Security Identification Display Area refers to zones within the airport where access is controlled for security purposes, and Notice to Airmen involves communications about essential information for flight operations, but they do not specifically address the issue of debris on runways and taxiways.
