What are the authorized code letters for a circular or random approach drop zone?

The authorized code letters for a circular or random approach drop zone are represented by "HO." This designation is specifically used to indicate a drop zone that requires or is suited for a circular or random approach pattern, thereby allowing aircraft to enter and exit the drop zone without a fixed approach direction.

Using the "HO" code helps ensure that all personnel involved in the operation understand the parameters and any special considerations associated with these types of drop zones. It promotes safety and efficiency during the drop process by clearly communicating the intended approach method to pilots and jumpers alike. Understanding these code letters is critical for effective coordination and execution of jump operations, especially when dealing with potentially variable conditions in the air.
