Obstacle limitation surfaces are intended to ensure which outcome?

• A. They establish obstacle clearance boundaries
• B. They designate taxiway signage height
• C. They guide noise abatement
• D. They govern runway length

Answer: (A)

Obstacle limitation surfaces are designed to protect aircraft during critical phases of flight by defining safe boundaries around the runway and instrument approach paths. They set how tall obstacles can be and where they can be located so that there is sufficient vertical and horizontal clearance for takeoff, climb, and landing, reducing the risk of interference with the flight path. This is why the primary outcome is establishing obstacle clearance boundaries. These surfaces are not about taxiway signage height, noise abatement, or runway length, which relate to different airport design considerations.
