What is the maximum slope landing nose-down angle?

• A. 4 degrees
• B. 6 degrees
• C. 8 degrees
• D. 10 degrees

Answer: (B)

Slope landings have to stay within limits so the helicopter remains clear of terrain and maintains stable control during touchdown. For the UH-60, the nose-down attitude allowed on a slope touchdown is six degrees. This limit is set to keep the forward portion of the fuselage and the landing gear from bottoming out or contacting the ground too early, preserve rotor/ground clearance, and maintain enough pilot visibility and stability as you settle onto the slope. Pushing beyond six degrees increases the risk of contact with the terrain, structural stress on the forward end, and loss of controllability during the critical touchdown phase.
