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 you are watched on

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

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 · 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 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.

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, marking formation faults (round and accordion) and line faults (slot and level misses) separately.
5.2
Identify one vertical-formation fault and one line fault, with a correction for the next jump.
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.

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.
