What should a pilot do if they are cleared to hold south on the 180 radial with an ATC clearance?

In this scenario, entering a hold using a teardrop entry is the appropriate action for a pilot who has been cleared to hold south on the 180-degree radial. When a pilot receives such an ATC clearance, they must first determine the radial associated with the holding pattern and their current position in relation to it. A teardrop entry allows the pilot to proceed towards the holding fix, making the correct adjustments based on the established radial.

The teardrop entry is particularly useful because it provides a way for the pilot to join and maintain the desired holding pattern while accounting for both the inbound and outbound legs of the hold. It involves a maneuver that requires a turn away from the holding course, allowing the pilot to orient themselves for the approach to the holding fix, before making a subsequent entry back into the pattern.

In this case, since the holding pattern is oriented to the south along the 180 radial, executing a teardrop entry is a strategic approach to ensure proper alignment and compliance with the clearance received from ATC.
