  5. JM/DZBRIEFING • In order for a stack to be effective, pre-jump planning must occur. • All information from aircraft exit to landing will be briefed, important points such as, detailed map recce of the DZ, wind speed and direction at working altitudes, check points under canopy will all be briefed/rehearsed. • Comprehension of winds aloft data and actual wind readings on the ground will assist in the effectiveness of the stack.

  6. STACK ORDER • Various factors will determine stack order. Due to the • effect of weight and gravity on canopy flight, typically the heaviest jumper will be selected as stack leader. • However, the most experienced jumper of the team may also be designated as the stack leader. • The remainder of the stack will be placed in order from heaviest to lightest. • All jumpers within the stack must remain flexible, factors such as slow openings or low speed malfunctions, may alter the pre-determined stack order. • The low jumper will always assume the role of stack leader; therefore it is imperative each jumper understands all details for the canopy stage. • Jumpers must always be prepared to change stack positions during descent.

  7. DIRT DIVE • A dirt dive is a systematic, physical and mental method of • organizing and rehearsing the jump sequence. • The dirt dive will be a walk through/talk through of the entire • descent from aircraft exit to landing. • Information from the JM/DZ brief such as pick up drills, holding area, check points, set up pattern and landings will be covered by the stack leader. • In addition, all contingency plans will be briefed in detail, • such as alternate DZ’s.

  9. PICK-UP/FOLLOW THE LEADER 140 METERS Jumpers will exit the aircraft at approximately 130 knots (240 KMH) with a 2 second delay between exits. Each second will represent approximately 70 meters separation between jumpers.

  10. PICK UP/FOLLOW THE LEADER DRILLS • Pick up drill will be utilized to close up the distance. As previously stated, the ideal separation between jumpers is 50’x 50’, horizontal and vertical. • Various factors such as tactics, wind data and aircraft approach on jump run will determine; • Cross Line Approach - 90° pick up drill • - 90° or 180° follow the leader drill.

  11. 90° PICK UP DRILL • On exit from the aircraft, each jumper will perform the 1st, 2nd and 3rd points of flight procedure while moving to their respective echelon position. • Once the jumper is near the echelon formation they will turn into the wind on aircraft heading and remain at 50% brakes. • When the stack leader has visual confirmation the remainder of stack is in position, pick up drills will be initiated. • The stack leader will turn 90° in the same direction as the echelon. Once the stack leader has passed by a jumper in echelon formation, they too will conduct a 90° turn into stack position. • When the stack has formed a single file, the stack leader will fly the appropriate pattern for the given wind conditions to the designated target area.

  13. 90° FOLLOW THE LEADER DRILL • On exit from the aircraft, each jumper will perform the 1st, 2nd and 3rd points of flight procedure while moving to their respective echelon position. • Once the jumper is near the echelon formation they will turn into the wind on aircraft heading and remain at 50% brakes. • When the stack leader has visual confirmation the remainder of the stack is in position, follow the leader drills will be initiated. • The stack leader will turn 90° away from the echelon, once this occurs all jumpers will peel off accordingly. • The stack leader will fly the appropriate pattern for the given wind conditions to the designated target area.

  15. 180° FOLLOW THE LEADER DRILL • On exit from the aircraft, each jumper will perform the 1st, 2nd • and 3rd points of flight procedure while moving to their • respective echelon position. Once the jumper is near the • echelon formation they will turn into the wind on aircraft • heading land remain at 50% brakes. • When the stack leader has visual confirmation the remainder of • the stack is in position, follow the leader drills will be initiated. • The stack leader will turn 180° into the echelon direction, once • this occurs all jumpers will peel off toward the stack leader. • The stack leader will fly the appropriate pattern for the given • wind conditions to the designated target area.

  17. QUESTIONS?

  18. DUTIES IN THE STACK • Stack Leader Duties • The low jumper will become the stack leader regardless of previous • planning and initiate pick up/follow the leader drills. • Additionally, the stack leader will assess drift en route and adjust the • pattern based on winds and jumper location. • Heading changes or turns must be predictable for stack to follow or • communicated via comms. • The stick leader consistently observes proximity of stack and flies • accordingly. • Depending on proximity, the stick leader should provide opportunities • for other jumpers to tighten up the stack by utilizing 45° or 90° turns.

  19. DUTIES IN THE STACK Stack Jumper Duties • Maintain air awareness; ensure your head is on a swivel observing other jumpers at all time. • All jumpers will fly in some type of brakes; this will ensure you have range to increase/decrease speed/altitude within the stack. • Jumpers will converge and position themselves as per brief, echelon left or right. • Each jumper should take a logical position in single file based on their relative altitude to other canopies, not exit order. • Jumpers will hold to allow other jumpers to pass if necessary. Be predictable and communicate. • Passes are best accomplished when the stack leader turns or if a jumper turns 45° off line of flight. • Anticipate turns in order to maintain proximity.

  20. HOLDING AREA • The holding area is an area upwind of the target and within the wind cone. • It is based on the winds at canopy altitude and not ground winds. • It may shift at different altitudes based on prevailing winds. • It also may be adjusted as necessary to keep the group in position to make the target and to enter the landing pattern. • The holding area is basically ground upwind where the stack will fly a carousel too burn altitude in a predictable pattern if necessary.

  22. LANDING THE STACK • All Jumpers must ensure trim tabs are released and all toggles are in hands prior to entering the landing pattern. • Prior to 1500’AGL the stick leader will fly to the left or right of the wind line in preparation for a penetration check. • The remainder of the stick may have to hold on brakes to maintain separation until the stack leader completes the penetration check and continues on with the landing pattern. • Jumpers may enter the pattern at any leg if altitude and position dictate. • All jumpers will maintain straight lanes on final. • Jumpers will turn onto base leg and final based on their relative position with the jumper directly in front of them. • If a jumper is at the same level or lower than the jumper in front of them, they will turn inside with a short base leg and remain on the inside of the other jumper. • If a jumper is higher than the jumper in front of them, they will turn outside with a longer base and remain outside. • Never fly directly behind another jumper. • KEEP YOUR HEAD ON A SWIVEL!

  23. Using the clock ray method, the stack leader will land at the 12 o’clock position of the “T”. The remainder of the stack will land as detailed. If the stack fails to hit the intended target area, ALL jumpers will remain with the stack leader and land as per. Wind Jumper #2 Stack Leader Jumper #3 Jumper #4

  25. SUMMARY • UNDERSTAND THE BRIEF AND DIRT DIVE • KNOW YOUR ROLE WITHIN THE STACK • FLY YOUR CANOPY! • KEEP YOUR HEAD ON A SWIVEL AT ALL TIMES • ABOVE ALL – LAND TOGETHER
