What is a crucial safety consideration when approaching or leaving a helicopter with the engine running?

When approaching or leaving a helicopter with the engine running, one of the most critical safety considerations is ensuring that the pilot can see you. This is essential because helicopters have large blind spots, particularly around the rear and sides. If the pilot is unaware of your presence, you could be in a position where you may inadvertently be struck by the rotor blades or the helicopter itself.

By ensuring that the pilot can see you, you establish better communication and create a safer environment. The pilot’s ability to maintain visual contact means they can monitor your movements and be more aware of your position as you approach or depart. This practice significantly reduces the risk of accidents and enhances overall safety when operating around a helicopter.

While the other options suggest various methods of approach, they do not prioritize the safety aspect of maintaining visibility with the pilot, which is paramount in preventing accidents when dealing with aircraft operations.
