What term describes the area around a parked aircraft that extends 25 feet beyond wingtips, nose, and tail where vehicle operation is restricted?

• A. Circle of Safety
• B. Jet Blast
• C. Arm/De-Arm Area
• D. Hot Cargo Area

Answer: (A)

Understanding the safety perimeter around a parked aircraft. The area around a parked aircraft that extends about 25 feet beyond the wingtips, nose, and tail is a restricted zone where vehicle operations are not allowed. This Circle of Safety helps prevent collisions with the aircraft and protects people from hazards like jet blast or prop wash if engines are started or tested nearby. It’s a clear, reusable boundary that guides drivers and ground personnel to keep safe distances from aircraft components and moving equipment.

Jet Blast is the dangerous airflow produced by running engines, especially behind the aircraft, but it’s not the defined perimeter used during parking. Arm/De-Arm Area refers to where weapons systems are armed or disarmed and isn’t the general vehicle-restriction zone around a parked aircraft. Hot Cargo Area involves handling dangerous cargo, not the standard safety boundary for parked planes.
