What you’re learning

You’ll learn to fly a pass-through: the group dives through vertical and comes back the way it came, everyone switching orientation at the pass. Dynamic 301 and Dynamic 302 come first, because they are its two halves. Everyone is head-down for a moment in the pass, so head-down to crest standard (Head-Down 202 or your country’s equivalent) is the guide for everyone.

In Australia, these jumps come under the tracking and angle rules, which need at least a Certificate C and an approved leader.

The jump

  1. Get into your slot and starting orientation as the leader turns off jump run, without passing the leader.
  2. Fly the outbound line, in a direction the group can safely come back along.
  3. Hold slot and level as the leader steepens toward the pitch-over.
  4. On the pitch-over, go through vertical with the group and switch orientation over your body.
  5. Get back into slot and on level on the return line straight away.

Your coach sizes the group, 2-way to 4-way, for the least experienced flyer (small groups).

Start on your weaker side, usually belly, so you come out of vertical onto your stronger side for the fastest part. Starting on back invites a cork on the high-speed switch to belly.

Breakoff:

  • With others: break off as in Dynamic 201, rolling from back to belly only on a clear line with no one above you. Flatten to a track on the briefed arc: turning in place puts you across the paths of everyone tracking away.

Who leads

The lead stays on belly for navigation. The leader briefs one of two ways to keep it there:

  • The handover, recommended outside training. The flyer coming out of the pass on belly takes the lead from Leader 1 and pulls the group onto the return line. Back flyers have plenty of power to come up and a belly flyer at that speed is twitchy, so pulling from the front keeps the group tight.
  • The re-transition, for example on a coached jump. The leader switches back to belly and keeps the lead and the abort call throughout.

Nobody is on belly for the 2–3 seconds of the vertical part, so under the handover the receiving leader owns navigation and the abort call from the start of it. As receiving leader, pull the group onto the return line on heading for the reciprocal.

Your coach is Leader 1 and flies the handover only once they judge you ready. Jumps outside training carry two approved leaders.

The return line crosses ground already covered, so the leader plans the opening point and keeps the reciprocal clear of jump run and other groups (What a movement-jump leader owns).

Useful drills

  • Tunnel: carving, belly-to-back flips and layouts at speed

Common mistakes

What happensUsual causesCheck
Belly flyers aren’t in slot on the angleThe dive is steeper than they can hold yetThe pass is off. The jump stays a straight angle
The group scattersSeveral flyers out of slot at onceThe leader steepens, then pulls out onto a straight angle
The receiving leader is lost before the handoverCorking or going lowLeader 1 steepens and pulls the group out. Nobody leads from their back
No belly lead within the briefed 2–3 secondsThe receiving leader is lost mid-passFinish your own switch, hold the reciprocal line and break off to plan
You’re low on belly, or lose sight of the leaderLow, or behind the lineTransition to back, because on belly you can float up blind through the diving group. Find the group and follow from below

When unstable, recover in your slot, in the recovery position through the vertical, because tracking away crosses other flyers’ paths.

If you lose the group across the pass, it comes back on the reciprocal of your line, below where it flew outbound, and you, still descending on that line, can meet it head-on. Hold an offset line and follow from below only once you can see the group. Otherwise separate, check the air and deploy higher.

Staying safe

Before the jump:

  • Gear check and audibles are in Freefly 100, and movement-jump planning, cloud and the two-group limit in Angles 101. Gear check the whole group. A second audible and an AAD are recommended.
  • In Australia, a group larger than a 3-way needs the drop zone safety officer’s written endorsement.
  • Dirt-dive the whole flow with slots and the transition key, and brief the abort calls, who leads through the vertical and the lost-leader plan.
  • As a guide, breakoff altitude up to a 4-way is usually 5,000 ft, and 5,500 ft for five or more.

In the air:

  • Clear the air before you switch. A transition flown blind is the classic collision set-up.

When you’ve got it

After each jump, debrief the video with your coach and log one correction.

You’ve finished Dynamic 303 when you fly two pass-throughs in a row that meet everything on the coach’s checklist below.

For coaches: the checklist, assessment conditions and coaching priorities

The checklist

1. Plan the jump

1.1
State the jump's single declared objective and success criteria.
1.2
Verify every participant's standard status against the track's course-internal safety standards: head-down competence at crest standard for all participants, both orientations, and the bail-out standard (the FFP-DY202 transition check).
1.3
Plan the line off jump run in a direction where it is safe to return back the same way, the leader picks the line so the reciprocal is clear of jump run, other groups' planned airspace and the opening points, and presents the flight path to the load.
1.4
Assign starting orientations weakest-orientation-first: each flyer starts on their weaker side, usually belly, so a student's first pass-through almost always starts on belly.
1.5
Name the leadership mechanism for the jump, the two-leader belly-led handover (recommended for non-training jumps) or the leader re-transitioning to belly across the pass (the alternative, e.g. on coached jumps, under which the leader retains lead and abort ownership throughout the pass), with the lead on belly at all times.
1.6
State breakoff (guide: 5,000 ft for groups up to a 4-way, 5,500 ft for a 5-way or larger; set at least 1,000 ft above the highest planned deployment) and deployment altitudes, and the lost-leader protocol (transition to back, turn onto a back angle, follow the group from below).

2. Prepare

2.1
Complete a freefly-specific gear check on self and group (handles, BOC, riser covers, closing loop, helmet, audible set and functioning; a second audible recommended).
2.2
Dirt-dive the full flow, exit, gather, the outbound line, the pitch-over point, the orientation switch, the return line and breakoff, with slot allocations and the transition key.
2.3
Brief the abort criteria and the leadership edge cases: belly flyers not in slot on the angle = pass aborted; a scattered group = the leader steepens, then pulls back out; who owns navigation and abort through the vertical segment (under the handover, the receiving leader from the start of the segment; under the re-transition mechanism, the leader throughout); the leader-loss protocol in both windows (before the pass: pass aborted, Leader 1 steepens and pulls out, no back-flying substitute; mid-pass: no belly lead within the briefed ~2–3 s = each flyer completes their own transition over the body, holds the reciprocal line, and the jump is over); the dropped-flyer rule for the reversing geometry (once the group has passed through, no rejoining across the reciprocal, hold an offset line, follow from below on the new direction only with the group re-acquired, otherwise separate and deploy higher after checking airspace); on a coached jump, the coach as Leader 1 flying the handover only when the coach judges the student ready to receive the belly lead; and arc ownership across the handover wherever a turn is planned (FFP-DY304).
2.4
Confirm exit order and separation with the load and any other movement groups (guide: two movement groups per load).

3. Perform, the pass-through

3.1
Gather into the assigned slot and starting orientation on exit, holding position while the leader turns the group off jump run and sets the line, without passing the leader.
3.2
Hold slot and level on the outbound line as the leader steepens toward the pitch-over, matching the leader's speed and pitch changes.
3.3
Transition through vertical on the leader's pitch-over, switching orientation over the body as the group comes through and re-establishing slot and level on the return line promptly.
3.4
Clear own airspace visually before the orientation switch, no blind transitions.
3.5
When briefed as receiving leader, take the belly lead through the pass, owning navigation and abort from the start of the vertical segment, acquiring the new sight picture as the group comes through, and pulling the group onto the return line within ±45° of the reciprocal heading.
3.6
Regulate closing speed on every approach so as never to pass the leader; if overtaking, slow and hold position.
3.7
Abort the pass when belly flyers are not in slot on the angle; on a scattered group the leader steepens, then pulls back out to a straight angle that breaks off normally.
3.8
Recover in slot from any instability, never track away from the group.
3.9
Execute the lost-leader protocol immediately on losing visual contact: transition to back, turn onto a back angle, and follow the group from below.
3.10
Transition to back immediately when low on belly without visual on the group, the FFP-DY202-trained recovery, regaining visual and following from below.
3.11
Apply the dropped-flyer rule after losing the group across the pass: do not rejoin across the reciprocal, hold an offset line, follow from below on the new direction only once the group is re-acquired visually, and otherwise separate and deploy higher after checking airspace.

4. Complete

4.1
Initiate breakoff at the briefed altitude (within −0/+300 ft).
4.2
Roll from back to belly only when on a clear trajectory with no one above.
4.3
Fan out on the briefed peel-off arc, flattening pitch to a track while checking airspace, never turning in place.
4.4
Deploy at the planned altitude after clearing airspace.
4.5
Fly the briefed canopy plan, holding off the jump-run line until the airspace is confirmed clear.

5. Review

5.1
Debrief against the declared objective using video.
5.2
Analyse own pass on video, slot and level through the pitch-over, the orientation-switch path, closing speed on the return line, identifying one correction for the next jump.
5.3
Write the jump up in the logbook with reflections naming the unit and skills assessed (e.g. "DY303 pass-through, received the belly lead through the vertical"), criteria results and current standing against the track's safety standards, the curriculum gives log entries meaning.

Criteria in bold are safety-critical: they protect the flyer and everyone else in the group. A coach should not sign off the course while a bold criterion is Not Yet Satisfactory, however good the rest of the flying. Outside a course they are strongly recommended practice. Regulation stays with your federation and your drop zone.

Assessment conditions

  • Sky jumps from 12,000 ft or higher (recommended), because through-vertical work needs the working time.
  • Each assessment jump is flown as a real 2–4-way.
  • A jump outside training carries two approved leaders for the belly-led handover. A coached assessment jump uses the coach as Leader 1: the handover is flown only when the coach judges the flyer ready to receive the belly lead, and other passes fly under the coach’s re-transition, with the coach keeping the lead and the abort call throughout.
  • Video of every assessment jump is required for a valid assessment: leader-flown, outside or helmet-mounted, with the flyer identifiable.
  • Equipment: a visual altimeter, a working audible (a second recommended), an AAD (recommended) and freefly-suitable gear.
  • Conditions within every participant’s cleared limits.
  • The assessor is a freefly coach current in dynamic or movement coaching and approved to lead movement jumps at the host drop zone, using this checklist.
  • Each criterion is marked Satisfactory or Not Yet Satisfactory. The result is internal to this course: it opens the track’s through-vertical jumps in this curriculum and gives no licence, crest, endorsement or jump permission.
  • The flyer always shows the Dynamic 202 belly-to-back transition live to the coach. Prior evidence alone never covers it.
  • As a guide, it takes about 8 coached jumps, at least 4 with a full pass-through and one as receiving leader, over at least two days or conditions within six months.
  • Tunnel carving and belly-to-back flips and layouts at speed can replace up to two jumps. Navigation, the handover and assessment jumps are sky only.
  • If you already fly pass-throughs, your coach can assess your record and one full pass-through with a coach leading, and you always show the Dynamic 202 belly-to-back transition live.

Coaching priorities

Safety first, then fun, then learning. Hold the bold criteria to the standard above, and have the standards conversation openly before the flyer spends money on jumps.

Explain weakest-orientation-first at the start as a safety decision. Judge honestly whether the flyer is ready to receive the belly lead. If not, fly the pass under your re-transition or keep the jump a straight angle, and present either as progress toward taking the lead.

End each debrief on something that went well, with one thing to improve. The first completed pass-through is the start of through-vertical flying.

Where this comes from
  • APF Freefly and Angles Guide (APF006): recovering in slot without tracking away (§4.3), the peel-off breakoff without turning in place, transitions over the body and fly zones on the angle (§5.10–5.13).
  • APF Operational Regulations: separation, the freefly rules and the tracking-and-angles rules (OR 9.1.4, 9.2, 9.9).
  • USPA Skydiver’s Information Manual 5-10: the movement-jump grading by transitions, groups per load, matching the jump to its least experienced flyer, and rolling from back to belly at breakoff only when clear.
  • Newcastle Sport Parachute Club, Hunter Valley angle and movement jump guidelines: movement groups per load, cloud, the leader’s approval and the navigation brief with the load master.
  • Community coaching on movement-jump leadership and safety: Christy West and Skydive Spaceland on leader duties and designing for the least experienced flyer, Skydive Arizona on back-fly, and Mason Corby on transitions in angle jumps and at breakoff.
  • The Freefly Project’s coaching guides: the pass-through flow, weakest-orientation-first, the belly-led handover and re-transition, the leadership edge cases, the footprint and cork-point reasoning, the abort criteria and lost-leader protocol, the mid-pass leader-loss and dropped-flyer lines, and the freefly breakoff guides.
Regulations where you jump

Regulations change, so each rule is given as context for where you jump. No national body defines prerequisites or safety standards for sky dynamic.

  • Australia (APF). These descents sit under OR 9.9 (tracking and angles): a Certificate Class C, the DZSO’s written endorsement for groups larger than a 3-way, and an approved leader (OR 9.9.3). An APF Freefly Coach can lead under OR 9.9.3 with DZSO approval.
  • A functioning audible altimeter is mandatory on every freefly descent (OR 9.2.3). All groups separate at least 1,000 ft above planned deployment (OR 9.1.4).
  • Mixed-orientation through-vertical jumps fall between the OR 9.2 crest requirements and the OR 9.9 endorsements, which leaves them to DZSO discretion. This course’s through-vertical standard is set stricter than that floor.
  • Hunter Valley (Newcastle Sport Parachute Club) sets no more than two movement groups per load without DZSO approval, no movement jumps in or near cloud, and a DZSO-approved belly leader for every movement group.
  • USA. USPA SIM 5-10 grades movement jumps by transition count (0, 1–3, 4+). A single pass, one transition per flyer, sits in the middle band. The difficulty is in the steepness and the transition hazard that SIM 5-10.E warns about, the same section that asks for an expert leader.
  • UK. British Skydiving FF2 is an example of a national head-down equivalent.
  • Elsewhere, check your national body and drop zone for the equivalent. Any drop zone may adopt this course’s standards as local policy.

The coaching priority order

Safety → Fun → Learning

Every course, briefing card and debrief on this site is built in this order. When two of them pull against each other on the day, keep safety ahead of fun, and fun ahead of getting through the course.

  1. 01 Safety

    Safety comes first on every jump. Nothing further down this list is worth a safety risk.

  2. 02 Fun

    Skydiving costs a lot. A jump you enjoy brings you back for the next coached one, and coached jumps are where the safety habits are practised.

  3. 03 Learning

    The skills each course teaches. They stick best after a jump that was safe and fun, because you keep practising what you enjoy.
