What is the starting elevation above EAE for the conical surface?

• A. 150 ft
• B. 100 ft
• C. 200 ft
• D. 250 ft

Answer: (A)

The conical surface is one of the obstacle clearance surfaces around an airport, and it begins at a fixed height above the airport’s elevation. Specifically, the starting elevation above EAE is 150 feet, at the end of the primary surface, after which the surface rises outward with a 20:1 slope. This standard height establishes a uniform vertical buffer right at the runway end before the surface starts to slope upward with distance. The other values don’t match the defined starting height for this surface, which is 150 feet.
