During what phase is it important for a JM to conduct proper coordination?

The pre-jump phase is crucial for successful coordination as it involves all the necessary planning and communication that set the stage for the parachute jump. During this phase, the Jumpmaster (JM) must ensure that all personnel are properly briefed about the jump parameters, aircraft procedures, and emergency protocols. It is essential that the JM coordinates with the jumpers to clarify roles, expectations, and the timing of the jump.

Additionally, proper coordination during this phase helps to mitigate risks and ensures that all team members are on the same page. It includes pre-jump checks to confirm that equipment is functional and that jumpers are in the proper mindset. By establishing clear communication and understanding among all participants before entering the aircraft, the JM lays the foundation for a safe and efficient jump. This focus on coordination in the pre-jump phase is a critical component of the overall safety and success of the parachuting operation.
