Dynamic 404

Combine following, mirroring and eagles

Following, mirroring and eagles combined into one jump.

What the course is about

You'll learn to fly following, mirroring and an eagle in one small-group jump, and to work towards the challenge jump that chains every discipline in the catalog. Dynamic 401, 402 and 403 come first, because each trains one of the three pieces on its own.
In Australia, tracking and angle jumps need a Certificate C, and larger groups need the matching Freefly Crest and the drop zone safety officer's written endorsement.

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
Fly the head-up component in role, the leader initiating head-up movement on belly, the followers holding the back slots, with the group in its angle/accordion arrangement, close and on level.

Can you fly the head-up component in your role, holding a back slot in the angle and accordion arrangement, close and on level?

3.4
Fly the offset eagle in role, the leader initiating the front layout back into an angle laterally offset from the outbound lane and heading back the way the group came, each follower going from the head-up back angle through a layout into a back angle on their pre-assigned side and chasing the leader back along the previous direction.

Can you fly the offset eagle in role, laying out back into an angle offset from the outbound lane and chasing the leader back the way you came?

3.5 Safety critical
Fly the offset-eagle lane discipline: each follower holds the outbound lane until their own layout key, reverses onto their pre-assigned offset side, and never crosses the leader's reciprocal lane.

Do you hold the outbound lane until your own key, reverse onto your assigned offset side, and never cross the leader’s lane?

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

1.5
State the breakoff plan, breakoff altitude, the head-up rotate-head-first rule, the back-flyer roll rule and deployment altitudes, with separation complete at least 1,000 ft above the planned deployment height (guides: 5,000 ft for freefly groups up to 4-way, noting most modern jumpers use 5,500 ft for any freefly group and will generally not accept 4,500 ft; the head-up-movement component raises the floor to 6,000 ft minimum, 6,500 ft for larger groups).
3.10
Once the group has reversed, never rejoin across the reciprocal: a dropped flyer holds an offset line, follows from below on the new direction only once the group is re-acquired, and otherwise separates and deploys higher after checking airspace.
4.1
Initiate breakoff at the briefed altitude (within −0/+300 ft), rotating from head-up to a head-first orientation first if breaking from a head-up segment, then turning onto a clear radial while flattening pitch to a track; never back-track away while still head-up.
4.2
If on the back at breakoff, roll to belly only once on a clear trajectory with no one above.
4.3
Deploy at the planned altitude, inside the group's planned opening airspace, after checking own 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 the line component-by-component against the plan on video, in the shared vocabulary.
5.2
Analyse own execution against competition-derived quality criteria: closeness of passes, synchronisation, uniformity of body position, no loss of balance.
5.3
Evaluate the flown difficulty against the briefed grade, setting the next jump's components and transition count accordingly.
5.4
Log the jump in the logbook naming the unit and components flown (e.g. "DY404, mixed snake, head-up component, offset eagle"), with criteria results and a short reflection, the curriculum is what makes the log entry meaningful.

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.
