Which member of the ground crew is not needed when using the cargo hook reach pendant (CHRP)?

The role of the Static Wand is primarily focused on providing visual and auditory signals to the helicopter pilot concerning the load being transported, especially during the load's approach and departure from the aircraft. This signal ensures safety by helping to prevent incidents during lift-off and landing phases. When using the Cargo Hook Reach Pendant (CHRP), which allows for a more efficient and safer method of hooking and unhooking loads from a distance, the function that the Static Wand plays is rendered unnecessary, as the system itself is designed to enhance the distance between the load and the helicopter.

In contrast, the Signal Person, Hook Up Person, and Load Coordinator all play crucial roles in ensuring that the loading operation is executed safely and efficiently. The Signal Person communicates with the pilot, the Hook Up Person physically attaches the load using the CHRP, and the Load Coordinator oversees the entire operation to ensure adherence to safety protocols and that all roles are performed effectively. Thus, the absence of the Static Wand in this particular scenario makes it the correct choice for the question asked.
