Which set correctly lists three common LZ hazards?

Which set correctly lists three common LZ hazards?

• A. Obstacles along the route, extreme heat, and loud noise
• B. Dry ground, good lighting, and no debris
• C. Uneven ground/obstacles, poor lighting or visibility, and debris from rotor wash
• D. Low winds, clear sky, and steady rotor speed

Answer: (C)

In LZ operations, the focus is on hazards that can prevent a safe touchdown and endanger personnel or aircraft. The three most common hazards are uneven ground or obstacles on the landing area, poor lighting or visibility that makes it hard to see hazards or judge distances, and debris kicked up by rotor wash which can obscure vision and damage equipment or injure people. The option that lists uneven ground/obstacles, poor lighting or visibility, and debris from rotor wash matches these real-world hazards, so it’s the best choice. The other sets describe favorable conditions or hazards that aren’t typically part of the standard LZ hazard trio, like good lighting, dry ground, or steady rotor speed, which are not hazards.
