Foreign Object Debris refers to any object found on airport movement areas - runways, taxiways, ramps, and aprons - that does not belong there and poses a hazard to aircraft operations. FOD includes a wide variety of items: loose hardware such as nuts, bolts, and washers; tools left behind by maintenance crews; catering equipment; wildlife; ice and snow fragments; chunks of pavement; luggage components; and virtually any other object that could be ingested by a jet engine, puncture a tire, or cause structural damage. The term is sometimes also used to refer to the hazard itself (Foreign Object Damage) - the actual harm caused to aircraft by such debris. FOD management is a critical safety responsibility at every airport. Airlines, ground handling companies, and airport operators conduct regular FOD walks - physical inspections of ramp and runway areas by personnel on foot or in vehicles - to identify and remove debris before it causes harm. Many airports also use automated FOD detection systems incorporating radar and cameras to continuously scan runway surfaces. Engine ingestion of FOD is one of the most dangerous outcomes, potentially causing compressor blade damage, surges, or fire. Ground crews are trained to account for all tools and equipment before and after any work near aircraft.

In Virtual Airline Operations

FOD is not directly simulated in most flight simulators, but awareness of FOD procedures reflects professional ground operations culture. Virtual pilots performing walkaround checks as part of their preflight routines are replicating the kind of ramp awareness that real-world crews use to spot potential FOD hazards. Some advanced simulator scenarios and airline training programs include FOD awareness as part of ground operations familiarization.
