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 you are watched on

What you are watched on

The same short list a coach ticks, in the same words. Nothing is hidden from you.

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 · Safety and altitudes

Safety and altitudes

Everything here is a recommendation with a reason behind it. The drop zone you are jumping at, and your own limits on the day, decide what happens.

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.

The altitudes here are the guides this site recommends, with the reasons on the full course page. Where the drop zone briefs something different, fly what the drop zone briefs.

Screen 4 · After the jump

After the jump

From the course's closing section, 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.

One fault, one correction

Before the video, and before anyone else speaks, name the one fault from the jump and the one thing you will change on the next jump. Keep it to one of each, so you have one clear thing to fly.

Write them into your notes at the bottom of this card, and they will be here next time you open it.

Record this jump

You can record the jump yourself, because your own read of your flying is worth keeping. A record counts as verified once a coach signs it.
