What does FOD stand for in the context of airport operations?

In the context of airport operations, FOD stands for "Foreign Object Debris." Understanding this term is crucial because it refers to any object on the runway or taxiway that can pose a hazard to aircraft during takeoff, landing, or taxiing. Airports place a strong emphasis on FOD management to maintain safety and operational efficiency. Proper identification and removal of foreign object debris are vital practices, as failure to do so can result in damage to aircraft, safety incidents, and operational disruptions.

The other terms presented may resemble FOD but do not align with standard industry terminology. For example, "Foreign Object Detection" is a process rather than a term specifically denoting debris. "Fixed Object Debris" is not widely recognized in aviation jargon, and "Flight Operation Directive" does not relate to the concept of physical debris on airport movement areas. Hence, "Foreign Object Debris" is the accurate term corresponding to safety protocols and airport maintenance practices.
