What is the maximum slope landing nose-up angle?

• A. 10 degrees
• B. 15 degrees
• C. 20 degrees
• D. 25 degrees

Answer: (B)

The key idea is that there’s a limit to how steep a nose-up attitude you can safely hold when landing on a slope. For a UH-60, 15 degrees is the maximum recommended nose-up slope landing angle. This limit helps ensure you maintain adequate rotor clearance from the slope and keep the helicopter’s center of gravity and control authority within safe bounds. If you try to land with a steeper nose-up angle, the risk of ground contact with the rotor system or tail-assembly increases, stability becomes harder to manage, and the chance you can’t control the descent or stop the drift rises. So, while smaller nose-up angles (like 10 degrees) are still safe, and you wouldn’t exceed this limit in practice, angles at 20 or 25 degrees go beyond what the aircraft is designed to handle on a slope, making such landings unsafe.
