If an obstacle cannot be removed, what must be done to indicate the hazard?

• A. Mark it
• B. Ignore it
• C. Paint it red
• D. Move the helicopter through

Answer: (A)

When an obstacle can’t be removed, the way to keep people safe is to clearly mark its location and boundary so everyone knows there’s a hazard. Marking provides a visible, standardized cue that communicates the presence of the obstacle to pilots, ground crew, and other operators, helping them judge safe distances and plan routes accordingly. The marking can include bright markers, flags, cones, signs, or warning lights, designed in a way that’s recognizable from different directions and in various lighting conditions. This approach keeps the hazard visible even if you can’t physically remove it, reducing the chance of a collision. Ignoring the obstacle isn’t safe because the danger remains unacknowledged. Painting it red offers visibility but may not establish a clear boundary or work consistently in all environments and lighting. Moving the helicopter through the obstacle is unsafe and contrary to safe operating practices.
