NINTH JUMP COMMAND10-41. Once the green light comes on, the PJM issues the ninth jump command, “GO.” Both JMs give the physical and oral command of “GO.” This is executed by bending forward at the waist and giving a sharp tap on the thigh or buttocks of the No. 1 jumper.10-42. The AJM observes the PJM and the No. 1 jumper. When the PJM issues the ninth jump command to their No. 1 jumper and the jumper begins to exit, the AJM immediately turns, acknowledges the green light is on, and then issues the physical and oral command of “GO” to the jumper. This action needs to occur in half a second in order to establish the proper interval between paratroop doors.10-43. Both JMs ensure they are in a position to best control the flow of jumpers without impeding the paratroop door or the safeties controlling USLMs. The safety grasps each USLM with their lead hand, and passes it back to their trail hand, ensuring the USLM is firmly seated against the intermediate anchor line cable support.10-44. The JM team must have situational awareness of their jumpers once the green light comes on. JMs: Control the flow and spacing and intervals between jumpers without impeding the flow of jumpers. Ensure jumpers' static line arms are extended once they begin moving. Remind jumpers to make eye-to-eye contact with the safety. Pause or stop the stick for any unsafe act or condition, fix the issue, and continue to exit jumpers if the green light is on. Monitor the jump caution lights for the red light.10-45. Safeties control the flow of jumpers and USLMs without impeding the flow of jumpers. They also: Ensure that there is a positive transfer of the static line between them self and the jumpers as they exit. Pause or stop the stick for any unsafe act or condition, fix the issue, and continue to exit jumpers. Watch for towed jumpers.CAUTIONBoth the jumpmaster and the safety must be prepared to initiate red light procedures at any time after the green light has been illuminated.
