Which is an optional runway spacing configuration of the Type-H?

• A. 100-200 ft
• B. 200-400 ft
• C. 50-150 ft
• D. 150-300 ft

Answer: (D)

This item tests understanding of what spacing is practical for a Type-H runway layout. The distance between runways needs to be enough to allow safe access for maintenance personnel and equipment, while also keeping the overall plant footprint reasonable. The 150-300 ft range provides a balanced compromise: it gives enough clearance for working space, passage of service vehicles, and maneuvering around components, without wasting excessive land area. Smaller ranges would be too tight for safe, efficient maintenance and vehicle access, risking interference with equipment and crews. A larger range would waste space and complicate layout efficiency without delivering proportional safety or operational benefits. So, 150-300 ft is the best choice because it meets practical access needs while maintaining a compact, efficient configuration.
