Dynamic 303

Fly a pass-through

The pass-through: the group comes through vertical and heads back the other way.

What the course is about

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.

What comes before it

Screen 2 · What to watch

What to watch

The same short list the flyer sees on their card, in the same words.

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.

Can you switch orientation over your body on the leader’s pitch-over and re-establish slot and level on the return line?

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.

If you are briefed as the receiving leader, can you take the belly lead as the group comes through and pull it onto a return line within 45 degrees of the reciprocal?

3.11 Safety critical
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.

If you lose the group across the pass, do you hold an offset line and follow from below, never rejoining across the reciprocal?

Screen 3 · What blocks a sign-off

What blocks a sign-off

A safety-critical item marked not yet stops the sign-off, however good the rest of the flying was. The rest of the jump cannot make up for it.

Safety-critical items on the short list

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.

If you lose the group across the pass, do you hold an offset line and follow from below, never rejoining across the reciprocal?

Everything this course says about breakoff and deployment

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).
2.2
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).
4.1
Initiate breakoff at the briefed altitude (within −0/+300 ft).
4.4
Deploy at the planned altitude after clearing airspace.

Recording a sign-off says what you saw on one jump. Permission to jump, and anything the drop zone requires, stay with the drop zone.

Screen 4 · Conditions

Conditions

Where the evidence is allowed to come from, and how much of it there needs to be.

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.

Performance evidence

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.

Screen 5 · Debrief

Debrief

Safety first, then fun, then learning. In that order, every time.

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.

One fault, one correction

Ask for their read before you give yours. Then leave them with one fault and one correction, in their words if you can get them. One of each is easier to carry onto the next load than six points.

A jump marked not yet is a jump to fly again. Tell them that as part of the debrief.
