PRIMARY INSTRUCTOR: SFC Tolman REFERENCES:
ASSISTANT INSTRUCTOR: SSG Roderick TC (pg 16-1) USASOC Reg (pg 199)

2. JUMP COMMANDS MOTIVATOR
As a JM, you will give a sequence of nine jump commands to ensure positive control of parachutists in the aircraft and immediately before exiting
Each command requires specific actions by each parachutist and when executed properly, ensure a safe exit from the aircraft
These commands are given verbally but, as a backup, hand and arm signals are also used with each command due to engine noise. The signals must be smooth, coordinated, and PRECISELY executed

JUMP COMMANDS
Seventh Jump Command
“SOUND OFF FOR EQUIPMENT CHECK”
The JM cups his hands and places the thumbs behind the ears
He gives the verbal command “SOUND OFF FOR EQUIPMENT CHECK”

35. JUMP COMMANDS
After the JM receives "All okay, JM”, the JM regains control of their static line from the safety, turns towards the skin of the aircraft, takes the number one parachutist position, and waits for slow-down procedures to conduct the door safety checks

36. JUMP COMMANDS
Once the aircrew has completed their slow-down checklist (slow to drop speed, open jump doors, deploy air deflectors, and position jump platforms), the loadmaster relinquishes control of the jump door to the JM by giving the JM a VISUAL AND/OR VERBAL SIGNAL, “ARMY YOUR DOOR” The JM then moves to the jump door area. Safety personnel then position themselves near the trail edge of the jump door to prepare to control the JMs static line for door procedures

37. JUMP COMMANDS DOOR SAFETY CHECK
The JM is now ready to perform the door safety check, He grasps the lead edge of the door with the lead hand and transfers control of his static line back to the safety telling them “SAFETY CONTROL MY STATIC LINE” and ensure the safety has positive control. Safety will respond “I HAVE CONTROL” before the JM turns to face the door.
NOTE: There are four parts to a complete door safety check

38. JUMP COMMANDS
The JM then grasps the trail edge of the door with the trail hand. Using only the lead hand, he ensures the pip pin is in place, securing the jump door in the open position.

40. JUMP COMMANDS
1. JM checks the jump platform:
Tapping the lead down lock with the lead foot and then the trail down lock with the trail foot and visually checking to ensure they are engaged
Placing the trail foot in the center of the jump platform and shifting his/her weight to the platform, ensuring the platform can support his/her body weight. This foot remains in place.
(During the USASOC JM course if a student moves their foot while in the paratroop door, that student must re-inspect the platform and continue with sequence or will be a NO GO for the PWAC Examination)

44. JUMP COMMANDS
2. Trail Edge of Door: With the trail hand, the JM starts at the top of the trail edge of the door, tracing all the way down to the trail down lock, then back to the top to ensure no sharp or protruding edges exist (Hand must remain in contact with the trail edge during the entire inspection)
3. Air Deflector: The JM then leans towards the trail edge and looks at the air deflector ensuring it is fully deployed and nods head twice acknowledging the air deflector is deployed.

46. JUMP COMMANDS
4. The JM must make Outside Air Safety Checks to ensure there are no unsafe conditions outside the aircraft (aircraft in the formation to the rear that are below drop altitude or other low-flying aircraft). From the rest position, the JM leans far enough outside the aircraft to make a proper air safety check, and visually checks outside the aircraft. The trail foot will be flat on the jump platform, while the lead foot will be placed flat on the floor of the aircraft.

47. JUMP COMMANDS Direction of flight Overhead Rear Straight down
The JM makes his checks in the following sequence:
Direction of flight
Overhead
Rear
Straight down
Straight to the front

48. JUMP COMMANDS
When the JM leans back inside the aircraft to assume the rest position, he WILL NOT collapse the trail elbow with the lead arm locked. This could cause accidental Reserve activation resulting in JM extraction from the aircraft prior to his planned exit. This could result in serious injury or death and will result in an automatic drop from the course
NOTE: The JM may lock his elbows, if necessary, to properly conduct Outside Air Safety Checks, or when checking for towed jumpers. However, the JM is not required to lock the elbows when performing these duties

49. JUMP COMMANDS
While the JM is in the rest position, he must also check the jumpers and then the safety to ensure no unsafe conditions have arisen inside the AC. This is conducted after both the initial outside air safety check and after the one minute time warning

50. JUMP COMMANDS
The JM continues observing outside the aircraft spotting for checkpoints en route to the DZ. In the absence of checkpoints, the Jumpmaster uses time advisories from the air crew, which must be identified during the JM / Pilot briefing
The Loadmaster should relay these time warnings to the JM or Safety by using pre-coordinated hand signals

51. TIME WARNINGS
Third Time Warning
“ONE MINUTE”

52. TIME WARNINGS
Approximately one minute from the green light, the safety passes along loadmaster time warning if the JM fails to hear it or to see his 1 minute checkpoint
The JM relays the 1 minute warning to the jumpers by leaning back, keeping his foot centered on the platform, facing the jumpers, and extending the index finger of his lead hand. He announces “ONE MINUTE” and continues to observe outside the aircraft for his 30 second checkpoint

53. TIME WARNINGS “THIRTY SECONDS” Thirty Second Time ADVISORY
JM announces, “THIRTY SECONDS.” The jumpers relay the announcement to the rear (verbal only)
After the JM has relayed the 30 second time advisory, he performs his final Outside Air Safety Check

54. TIME WARNINGS “THIRTY SECONDS” Thirty Second Time ADVISORY
The JM relays the 30 second advisory to the jumpers by leaning back, keeping his foot centered on the platform, facing the jumpers, and extending his lead hand to the jumpers with the index finger and thumb held close together. He announces “THIRTY SECONDS” The jumpers relay the announcement to the rear (verbal only) and then conducts his final outside air safety check and observes for his reference point or USAF advisory, determines the aircraft is about 10 seconds out (20 seconds for bundle drops)

55. TIME WARNINGS Once again, he leans out and visually checks
Direction of flight
Overhead
Rear
Straight down
Straight to the front

56. TIME WARNINGS
The JM completes the final Outside Air Safety Check and positively identifies Drop Zone Markings. Determines when the aircraft is about 10 seconds (20 seconds for bundle drops) from the release point
Unsafe Condition Outside Aircraft: If the JM observes any unsafe conditions outside the aircraft, JM notifies the Loadmaster by a preplanned arm-and-hand signal (for example, a cutting motion across the throat) that a no-drop situation exists for this pass

57. TIME WARNINGS
The JM maintains a firm grasp on the trail edge of the door with the trail hand and turns toward the cargo area. The PJM and AJM make eye-to-eye contact and give each other the thumbs-up signal, (given to the instructor for the course) indicating that there are no unsafe conditions outside the aircraft and that they are ready to exit personnel. This procedure is followed when exiting personnel from one or both doors, as long as both doors are open (active)

58. JUMP COMMANDS “STAND BY” Eighth Jump Command
This command is given about 10 seconds before the aircraft reaches the release point and only after the aircraft has cleared all obstacles near the DZ

59. JUMP COMMANDS “STAND BY” Eighth Jump Command
Starting at the shoulders, the JM extends and joins his index and middle fingers, curling the remaining fingers and thumb of each hand toward the palm
He extends his arm down to the sides at a 45 degree angle by locking the elbows, and points to the jump door

60. JUMP COMMANDS “STAND BY” Eighth Jump Command
After issuing the eighth jump command, the JM receives the first parachutist's static line with the lead hand and passes it to the trail hand to control it until the parachutist exits. The JM will continue to spot over the first parachutist’s left/right shoulder and when the panels line up with the trail edge of the door the JM will check for the green light and issue the 9th Jump Command

61. “GO” JUMP COMMANDS Ninth Jump Command
The green light is the final time warning on USAF aircraft. It tells the JM that as far as the aircrew is concerned, conditions are safe and it is time to issue the ninth jump command

62. JUMP COMMANDS Ninth Jump Command
Once the aircraft is over the drop zone and the jump caution light is green the JM gives the verbal command “GREEN LIGHT GO” and taps the first parachutist on the thigh. Once all jumpers have exited the JM rechecks the jump caution lights, RECEIVES CONFIRMATION FROM INSTRUCTOR, and exits the aircraft. The Safety will then check to the rear of the aircraft to ensure that all jumpers have cleared the aircraft.
