When separating SVFR helicopters from IFR helicopters, what separation methods are applicable?

The correct choice is based on the understanding of how SVFR (Special Visual Flight Rules) helicopters can be effectively separated from IFR (Instrument Flight Rules) helicopters. The integration of various separation methods helps maintain safety and efficiency in airspace management.

Utilizing non-radar separation is crucial in areas where radar coverage may not be available or while relying on the visual observations of pilots and controllers. This method can include using visual cues and distance estimates to ensure aircraft maintain safe separation. Visual separation allows a controller to ensure that aircraft can visually see and avoid each other, as long as they have adequate visibility conditions.

Additionally, employing IFR radar separation provides a robust means of maintaining separation under instrument conditions, ensuring that IFR helicopters can be monitored via radar with specific separation standards, even when other methods may not be applicable.

The combination of these separation methods—non-radar, visual, and IFR radar—ensures a comprehensive approach to managing the different operational requirements and characteristics of SVFR and IFR operations, facilitating both types of aircraft to operate safely in shared airspace.
