Dynamic 301

Fly vertical into movement

Building a vertical formation, then leaving it on a line.

What the course is about

You'll learn to start a jump as a vertical formation and finish it on a line behind a belly leader. Dynamic 202 comes first, because its belly-to-back transition is how you find the group if you lose the leader.
So does Head-Up 301 or Head-Down 301 in the orientation you'll fly, because the jump starts with docks in a vertical formation. In Australia, this jump comes under the freefly and 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.

3.2
Build the accordion on the briefed key, taking the briefed grips and holding level through the build.

Can you build the accordion on the leader’s key, taking your briefed grips and holding level through the build?

3.4
Break grips on the leader's key, coming out in the assigned orientation, belly beside the leader, back on the other line, establishing the slot as the leader sets the angle.

Can you break grips on the leader’s key and come out in your assigned orientation as the leader sets the angle?

3.5 Safety critical
Execute the off-key rule after missing the grip-release key: hold orientation, let the group depart, and follow the group's line from below, transitioning only in clear air, never late into the departing group.

If you miss the grip-release key, do you hold your orientation, let the group go and follow their line from below, transitioning only in clear air?

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.

Everything this course says about breakoff and deployment

1.6
State the breakoff and deployment altitudes (guides: 5,000 ft up to a 4-way, 5,500 ft for five or more; where the vertical segment is flown head-up the floor rises, head-up groups 5,500 ft minimum; breakoff at least 1,000 ft above the highest planned deployment), the fan-out plan, and the lost-leader protocol.
4.1
Initiate breakoff at the briefed altitude (within −0/+300 ft).
4.4
Deploy at the planned altitude after clearing airspace.
5.3
Log the jump with criteria results and a reflection naming the unit and skills assessed (e.g. "FFP-DY301 vertical into movement, head-up round, back-line departure, held slot to breakoff"), entries like this make the logbook a meaningful training record.

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), since the build and the moving part both need working time.
Assessment jumps are flown as a real group within the 2–4-way guide: a qualified leader and at least one other flyer, completing the full sequence from round to angle.
Video of every assessment jump is required, outside camera or leader-flown, with the flyer identifiable.
Equipment: a visual altimeter, a working audible (a second recommended), an AAD (recommended) and freefly-suitable gear.
The group declares the flight path to the load and manifest. Conditions stay within every participant's cleared limits.
The assessor is a freefly coach current in dynamic or movement coaching, using this checklist.
Each criterion is marked Satisfactory or Not Yet Satisfactory.
As a guide, it takes about 8 coached jumps, at least 4 through the full sequence in both departure slots, over at least two days or conditions within six months.
Tunnel time builds vertical formation work and belly-to-back transitions. Exits, navigation and breakoff are learned in the sky.
If you already fly this jump, your coach can assess you on two jumps, or from your logbook, video and tunnel records backed by sky jumps.

Performance evidence

After each jump, debrief the video with your coach and log one formation fault and one line fault, each with a fix. You've finished Dynamic 301 when you fly two jumps 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. Plan the session to be enjoyable, with one objective per jump and a tempo that suits the group. The coach leads, and the flyer flies each departure slot in turn. End each debrief on something that went well, with one thing to improve.

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.
