On which side of a helicopter is refueling typically done?

Refueling a helicopter is typically done on the right side due to operational and safety considerations. The right side allows ground personnel to refuel while maintaining a safe distance from the main rotor which is on the left side, minimizing the risk of injury. Additionally, many helicopter designs incorporate refueling systems that are more conveniently accessible from this side, streamlining the refueling process. This standardization helps ensure that crews can perform refueling efficiently and safely across different aircraft types.
