Which term describes a substance, debris, or article alien to a vehicle or system that could cause damage?

• A. Foreign Object Debris
• B. Foreign Object Damage
• C. Foreign Objekt Debris
• D. Foreign Object Elimination

Answer: (A)

The main idea here is the term used for anything that doesn’t belong on or in an aircraft or system but could cause harm. Foreign Object Debris is the exact label for that offending item—whether it's a small screw, a rock on the runway, a tool left in a compartment, or ice, anything alien to the aircraft that could lead to damage if it enters engines, ducts, or sensitive mechanisms. Choosing this term is best because it names the object itself and its potential to cause damage, rather than describing the harm that might result. The other options either refer to the damage that could occur, are misspelled, or aren’t standard terminology for this concept.
