A. Exit & Freefall
- Initiating track
- First locate a point on the horizon.
- Smoothly extend both legs fully to initiate forward motion.
- Control in the delta and track positions:
- Dip one shoulder slightly in the direction of the turn to make heading corrections (instructor technique may differ).
- Make only small corrections.
- Slowly extend your torso by stretching your shoulders toward your ears and flatten your arch.
- Fully extend your arms to the side 90 degrees to your spine and level with your hips (instructor technique may vary).
- Refining the track
- Once establishing a heading in a positive forward dive, fully extend both legs with your knees locked and toes pointed.
- Stiffen your body slowly into a slight reverse arch, pushing down and forward slightly with your shoulders, while keeping your hands level with your hips.
- Continually adjust your body position to effectively meet the relative wind.
- Tracking practice procedure
- Experienced jumpers often allow only five to ten seconds to obtain adequate separation.
- Practice entering and refining an on-heading track for five seconds, reversing direction, and repeating.
- Tracking jump safety
- Fly exactly perpendicular to the jump run to avoid others up and down the line of flight.
- Always plan tracking dives with other groups in mind.
- Learn to control a track on heading first, then develop techniques for pitch and speed.
- Clear and pull (AFF students only—IAD and static-line students have already met the clear-and-pull requirement in Category C.)
- A clear and pull is used for emergency exits and pre-planned low-altitude jumps.
- Use a familiar, stable exit technique.
- Present your hips to the relative wind and execute normal pull procedures (without wave-off) to deploy within five seconds of exit.
- Expect the parachute to open in relation to the relative wind, not overhead as usual.
- The sequence consists of a clear and pull from two altitudes:
- first from 5,500 feet
- once successful, from 3,500 feet
B. Canopy
- Braked turns:
- Performed correctly, braked turns provide the quickest heading change with the least altitude lost.
- A braked turn may be the best choice when a quick heading change is needed.
- when suddenly encountering another jumper under canopy or someone in the landing area
- recognizing an obstacle
- too low to recover from a full-flight turn
- Practice braked turns.
- From the slowest speed at which the canopy will fly, raise one toggle slightly to initiate a heading change in the opposite direction.
- Try to change heading as quickly as possible without banking or stalling.
- Using brakes to attain the maximum glide and minimum descent:
- On lower-glide designs, the minimum descent may begin nearer the half-braked position.
- On higher-glide designs, the minimum descent may be nearer the three-quarter braked position or just prior to a full stall (reverse flight).
- Some canopies achieve minimum descent using the back risers instead of the toggles.
- Minimum sustainable descent (float):
- allows the jumper to remain above other jumpers on descent
- allows the canopy to cover a greater distance
- Recognizing and adjusting for minimum descent and maximum glide path
- Look ahead to the point on the ground that appears not to rise or sink in your field of vision.
- Everything before that point appears to fall.
- Everything beyond it appears to rise.
- That point is the projected landing point on the canopy’s current glide path.
- Pull the toggles down slightly to see if the stationary point moves farther away.
- If so, the glide path has flattened.
- The canopy will cover more distance.
- Repeat until the point begins to move closer, then return to the maximum glide position that you have just determined.
- When flying downwind in maximum glide:
- As the winds decrease at lower altitudes, your glide path will become steeper.
- The actual landing area will be closer than you initially anticipated.
- Increasing the glide when flying against the wind:
- in lighter winds, may improve distance
- in stronger winds, may slow the canopy too much and reduce its upwind range
- Braked pattern and landing approach
- Fly one entire landing pattern in at least half brakes, to determine the effect on glide path.
- Plan for a change in glide path.
- A lower-glide design may require a smaller pattern when flown in brakes.
- A higher-glide design may require a bigger pattern when flown in brakes; extend the final approach to avoid overshooting the target.
- Fly final approach in quarter to half brakes.
- Flare carefully from the braked position:
- Practice high to avoid a stall.
- To get the best flare may require a shorter, quicker stroke initiated lower to the ground.
- The stall may occur more abruptly.
- Plan for a PLF.
- A smaller canopy may descend too quickly in deep brakes for a safe braked landing.
- Accumulate two unassisted landings within 82 feet of the planned target.
C. Emergency Procedure Review
- Recognizing and avoiding power lines
- Expect power lines along roads, between buildings, in paths in the forest, and in random places.
- Scan every 500 feet of descent into an unfamiliar landing area and continually scan below 500 feet.
- Power-line landing emergency procedures (training harness): Refer to Section 5-1 of this manual.
D. Equipment
- Pack at least one parachute with the assistance of a knowledgeable packer.
- Discuss the most important points of packing:
Note: An FAA rigger is your best resource for this discussion.
- lines straight and in place in the center of the completed pack job
- slider up
- tight line stows to prevent premature line deployment
- Perform a pre-jump equipment check on another jumper who is in full gear.
- “check of threes” in the front
- three-ring assembly (and reserve static line)
- three points of harness attachment for snap assembly and correct routing, adjustment, and no twists
- three operation handles—main activation, cutaway, reserve
- pin check back of system, top to bottom
- reserve pin at least halfway seated (and automatic activation device on)
- main pin fully seated
- ripcord cable movement or correct bridle routing
- if collapsible pilot chute, check the indicator window
- activation handle in place
- check personal equipment (“SHAGG”)
Shoes—tied, no hooks
Helmet—fit and adjustment
Altimeter—set for zero
Goggles—tight and clean
Gloves—lightweight and proper size
E. Rules & Recommendations
- Study USPA BSRs applicable to USPA A-license holders, including Sections 2-1.B; G.2; H.2; I.1.a, 2, and 3; L.5; and M.
- Study USPA recommendations on training following periods of inactivity, SIM 5-2.
F. Spotting & Aircraft
Note: This section should be conducted by a jump pilot or USPA Instructor.
- Acting without a rated USPA instructor during routine jump operations and aircraft emergencies
- The person spotting the load usually serves as the jumpmaster.
- In larger aircraft, the jumpmaster should establish an exclusive chain of communication with the pilot.
- A communication assistant should be able to communicate directly with the pilot and the jumpmaster simultaneously.
- Other jumpers should not get involved in communication among the pilot, communications assistant, and the jumpmaster.
- Review of low-altitude exit procedures
- The jumpmaster must determine if jumpers are over a safe landing area and communicate this information to the pilot.
- Establish firm altitudes at which certain aircraft emergency decisions would be made (DZ policy):
- altitude below which all jumpers will land with the aircraft
- altitude below which all jumpers will jump using their reserves
- altitude below which all jumpers will jump and immediately use their main parachutes
- Jumpers must maintain correct weight distribution in the aircraft, especially during emergency exit procedures.
- The effect of the winds aloft on the exit point
- Subtract the speed of the headwind on jump run (if flown into the wind) from the true airspeed of the aircraft to determine the ground speed.
- Jumpers first get thrown forward on exit (approximately 0.2 miles in calm winds, less with headwind) from residual aircraft speed and then fall straight down or blow toward the target.
- The winds aloft will cause freefalling jumpers to drift according to the wind’s strength and direction.
- Winds generally diminish at lower altitudes.
-
Average the speed and the direction of the winds from exit altitude to 3,000 feet AGL to estimate freefall drift. See the example in Table 4-F.1 for a sea-level drop zone:
- If flying jump run upwind, use the average heading of 270 degrees.
- Aircraft forward throw is approximately 1/8-1/4 mile upwind in the light-to-moderate headwind.
- Jumpers fall for one minute, drifting at 1/4 mile per minute for 1/4 mile of drift downwind.
- Since the forward throw and the freefall drift approximately cancel each other, the ideal exit point is almost straight over the ideal opening point in this example.
- Group separation on jump run (SIM 5-7).
- Perform all duties on jump run with minimum assistance, including—
- operating the door (if the pilot allows)
- monitoring progress during jump run
- directing the pilot to the correct spot
- choosing the correct exit point
