What are the CRFFAA dimensions?

• A. 500 ft from runway centerline and 1,650 ft from each runway end.
• B. 500 ft from runway centerline and 3,300 ft from each runway end.
• C. 600 ft from runway centerline and 2,800 ft from each runway end.
• D. 400 ft from runway centerline and 2,000 ft from each runway end.

Answer: (B)

CRFFAA dimensions define the designated safety and access zone around a runway for crash-fire-rescue operations. The lateral distance of 500 ft from the runway centerline creates a wide, unobstructed corridor on both sides so ARFF apparatus can position, connect hose lines, and operate without crowding the centerline area. The longitudinal distance of 3,300 ft from each runway end provides enough space beyond the threshold for staging, maneuvering, and deploying equipment while keeping operations clear of aircraft on the runway. This combination ensures rapid, safe access to the incident scene and protects both responders and ongoing airport operations. Other distances reduce either the side clearance or the end buffer, which would limit vehicle maneuverability or safety margins for emergency response. Therefore, the standard CRFFAA dimensions are 500 ft from the runway centerline and 3,300 ft from each runway end.
