Non-precision slopes include which ratio?

• A. 60:1
• B. 50:1
• C. 70:1
• D. 30:1

Answer: (B)

Non-precision slopes use a fixed, gentle descent path described by a horizontal-to-vertical ratio. The standard for these approaches is 50 units of horizontal distance for every 1 unit of vertical drop, i.e., a 50:1 ratio (about a 2% grade). This keeps the descent gradual while relying on lateral guidance alone, ensuring obstacle clearance without vertical guidance. The other ratios would imply steeper or shallower gradients than what non-precision procedures typically use, so 50:1 is the best representation of non-precision slopes.
