Night time ground slope is?

Night time ground slope is?

• A. 2°
• B. 3°
• C. 7°
• D. 4°

Answer: (B)

Night operations require a stricter ground slope limit because reduced visibility makes terrain judgment and control of the load more difficult. The accepted maximum night-time ground slope is three degrees. This limit provides a safer margin for touchdown, pickup, and load handling under limited visibility and helps prevent tipping or sliding as the helicopter sets down or picks up the load. A smaller value, like two degrees, is more conservative than the standard night limit, while larger values such as four degrees or seven degrees exceed what is considered safe at night and increase the risk of mishaps.
