What is the ending elevation for the transitional surface?

What is the ending elevation for the transitional surface?

• A. 7500 ft from runway centerline
• B. 150 ft above EAE
• C. 500 ft + EAE
• D. 0 ft

Answer: (B)

Transitional surfaces are imaginary planes that rise outward and upward from the runway ends to protect approach and departure paths. The ending elevation of that surface is fixed at 150 feet above the airport’s field elevation (often expressed as 150 ft above EAE). So the correct choice reflects this standard height, not a horizontal distance, not zero height, and not a higher, nonstandard value.
