Where will marshal control clear transient helicopters during Case III operations?

During Case III operations, which typically involve reduced visibility conditions, transient helicopters are cleared to specific holding patterns to ensure safe and efficient operations. The correct choice indicates that transient helicopters are directed to the CV-3 holding area or the Starboard Delta. This area is designated for managing the flow of transient helicopters effectively, allowing them to maintain safe separation from other air traffic while preparing for either recovery or further instruction.

The choice of CV-3 holding or Starboard Delta specifically serves to optimize traffic management during complex operations, as it provides a strategic position relative to the carrier's launch and recovery operations.

In the context of the other options, they refer to different holding areas that are either not designated for common transient helicopter operations or are aligned with different types of operations or flight patterns that do not specifically pertain to transient helicopters during Case III. This differentiation is critical for maintaining operational efficiencies and safety in the constrained environment characteristic of Case III conditions.
