When approaching a helicopter, what should you avoid doing because it is not visible to the pilot?

Avoiding ducking under the body or tail boom of a helicopter is crucial because this area is not visible to the pilot. Helicopters have significant blind spots, especially near the tail and under the body, making it impossible for the operator to see someone in those positions. This can lead to severe accidents, as the pilot may not be aware of your presence when the helicopter is in motion.

It's essential to maintain safe distances when approaching a helicopter and to approach from designated safe zones, typically front and side areas where the pilot can see you. Maintaining visibility is crucial for ensuring safety around rotating blades and other moving parts. This approach minimizes the risk of accidents, as pilots rely on visual acuity to ensure a safe operation.
