Which term describes safe passage air corridors as a type of volume in airspace management?

• A. Origin volumes (friendly/hostile)
• B. Air corridors (safe passage)
• C. Prohibited volumes
• D. Restricted volumes

Answer: (B)

Safe passage air corridors are designed channels within controlled airspace that provide a predictable, protected route for aircraft to move from one point to another. They define specific lateral and vertical boundaries, and often operate with assigned altitude bands, times, and coordination with air traffic control to maintain separation from other traffic. This makes them a volume purpose-built for allowing safe transit, as opposed to zones that restrict or prohibit operations.

Prohibited volumes are no-entry zones, where flight is not allowed; restricted volumes require special authorization to enter; origin volumes relate to the origin or source of activity rather than a path for transit. The term air corridors precisely captures the idea of a designated route used to ensure safe passage through airspace.
