What are the two pre-jump formations?

The two pre-jump formations commonly recognized in parachuting are the extended rectangular formation and the horseshoe formation.

The extended rectangular formation is typically used when conducting jumps that require a large separation between individual jumpers to maintain safety and a clear airspace. This formation allows for optimal spacing and facilitates the safe deployment of parachutes without the risk of entanglement.

On the other hand, the horseshoe formation is utilized when a more compact arrangement is needed, often allowing jumpers to maintain visual contact with one another while still adhering to safety protocol. This formation is effective in certain operational scenarios where quick maneuverability and communication among jumpers are essential.

Choosing these two formations highlights their strategic importance in jump planning and execution, emphasizing safety and efficiency in parachute operations. Other options, while representing various arrangements, do not encompass the two primary formations utilized universally in pre-jump protocols.
