FOD stands for which of the following?

• A. Foreign Object Damage
• B. Foreign Object Debris
• C. Fuel Onboard Damage
• D. Flight Operations Data

Answer: (A)

Foreign Object Debris is the standard meaning of FOD in airport operations. It refers to any loose object or debris that shouldn't be in areas where aircraft operate. These objects can be on runways, taxiways, gates, or maintenance areas, and they pose a hazard because an engine could ingest them or they could strike tires, blades, or structural components. The key point is that the danger comes from the object itself, not the damage it might cause, which is why Debris is used in the term. Saying Foreign Object Damage would focus on the consequence rather than the object, and the other options don’t fit the acronym used in aviation safety.
