Name three critical factors to evaluate when selecting an LZ.

• A. Time, Color of terrain, Proximity to water
• B. Clear approaches/departures with wind; Size/shape; Ground slope/obstructions
• C. Size/shape, ground slope/obstructions, and clear approaches/departures with wind
• D. Distance to enemy positions, Noise restrictions, and Lighting conditions

Answer: (C)

Safe rotor-wing landings rely on three essential considerations: clear approaches and departures with wind, the size and shape of the landing area, and the ground slope with obstructions. Clear approaches and departures with the wind ensure you have a predictable, controllable path for landing and lifting off, reducing drift and the chance of hitting obstacles while the rotor wash is active. The wind direction and speed dictate which corridor of the LZ can be used safely and how you align the aircraft during approach and exit.

The size and shape matter because the aircraft must have enough footprint to land, settle, and stop without encroaching on edges or nearby hazards. A properly sized, well-shaped area allows for stable touchdown, safe rotor clearance, and adequate room for maneuvering, especially when multiple aircraft are involved or when you need to account for surge and hover.

Ground slope and obstructions are critical because sloped terrain can affect stability and control, and obstructions—trees, rocks, power lines, vehicles, or buildings—pose collision risks during approach, landing, or departure. Evaluating these factors together helps ensure a safe, controllable LZ where pilots can operate within margin and minimize the chance of rotor, tail rotor, or fuselage strikes.

Other options may touch on factors like camouflage, timing, or security, but they do not directly determine the safety and feasibility of landing and lifting off in a given zone.
