Which scenario defines a Vehicle/Pedestrian Deviation (VPD)?

• A. A pilot deviating from regulations.
• B. Pedestrians or vehicles entering any portion of the airport movement areas without authorization from ATC.
• C. An ATC action causing less than minimum separation.
• D. An incident with ample time to avoid collision.

Answer: (B)

Vehicle/Pedestrian Deviation occurs when a person or a vehicle enters any part of the airport movement areas without authorization from ATC. This definition directly matches the scenario described, where pedestrians or vehicles move into movement areas without clearance, creating a potential safety risk for aircraft operations. The other situations involve different issues: a pilot deviation relates to aircraft procedures or regulations, an ATC action causing less than minimum separation is an air traffic control separation issue, and a near-miss with ample time to avoid collision does not specify unauthorized entry into movement areas.
