What is the primary reason TOFA is more stringent than ROFA?

• A. Aircraft wings often extend beyond the paved surface.
• B. TOFA is used only for large airports.
• C. TOFA has stricter lighting requirements.
• D. TOFA applies to ground vehicles only.

Answer: (A)

During takeoff and landing, an aircraft’s wings and other surfaces swing into positions that can extend beyond the paved runway footprint. This means anything near and beyond the runway edges can pose a collision risk when the airplane rotates and climbs or descends. Because TOFA must account for those wing and tail extensions, it requires stricter clearance than ROFA, which focuses more on the immediate runway obstacle-free area rather than the extended wingspan outside the paved surface. The other options don’t capture this core reason: TOFA isn’t defined by airport size, lighting differences aren’t the primary factor, and TOFA isn’t limited to ground vehicles.
