Which sign marks the exit boundary of the Runway Safety Area/Obstacle-Free Zone?

• A. ILS Critical Area Boundary
• B. Runway Safety Area/Obstacle-Free Zone Boundary
• C. Taxiway Location
• D. Runway Location

Answer: (B)

Identifying boundary signs for protected runway areas is the key idea. The sign that marks the exit boundary of the Runway Safety Area/Obstacle-Free Zone is the Runway Safety Area/OFZ Boundary sign. It’s placed where you leave the protected RSA/OFZ so pilots know they’re entering the non-protected movement area. The sign is designed to be easily read from the taxiway side and typically features a yellow background with black lettering that reads the boundary name. This distinguishes it from the ILS Critical Area Boundary sign (which marks the ILS critical area boundary), the Taxiway Location sign (which shows your current taxiway), and the Runway Location sign (which indicates the active runway).
