Dynamic 201

Fly a near-vertical back angle

Holding a back slot as the line steepens toward vertical.

What this unit covers

This is the Dynamic track's entry unit, and it opens a 200 tier whose purpose is to build toward transitions through vertical, the pass-through and the flock and roll, by stress-testing each flyer at near-vertical speed and pitch while pulling out the way you came in, which minimises risk.
The tier's shared jump format: the group steepens toward vertical and shallows back onto the same line, never passing through vertical, so each flyer meets the speed and pitch a real pass will demand while the highest-risk element, the pass itself, stays out of the jump until FFP-DY303.
The rest of it
This unit covers the back side of the tier standard: holding the back slot on a very steep, near-vertical angle through the dive and the pull-out, relative to a coach-leader and a small group.
FFP-DY202 covers the belly side and the bail-out standard (the belly→back transition check); completing both completes the tier (the project's coaching doctrine, 2026-08-05 dynamic track redesign).
Leadership doctrine for through-vertical jumps lives in FFP-DY303 and FFP-DY304. How dynamic relates to vertical and movement. Dynamic blurs the line between vertical and movement flying, the more advanced the jump, the closer it sits to pure vertical.
A basic pass-through (the group dives through vertical and returns the way it came) covers less than half the horizontal distance of a straight angle, because part of the jump is spent purely vertical. A double pass-through covers less than a third.
By four or five pass-throughs the jump approaches a purely vertical column of air, eagle and layout territory.
The key skills for basic dynamic jumps are therefore HD-crest-level vertical flying and belly and back angles, with advanced belly angles at high speed the most important, because that is the classic cork point on a pass-through: flyers start on their back where they are comfortable, transition to belly at speed, and cork (the project's coaching doctrine, The Freefly Project 2026-07-27).
This unit's format takes the straight angle to the near-vertical end of that spectrum: the dive approaches purely vertical flight and the pull-out returns along the entry line, building the speed-and-pitch tolerance the pass-through will demand. Mastery track, no sign-off. Completion of this unit is a milestone, not a permission: it admits the flyer to FFP-DY202 and to jumps of this format within this curriculum, and nothing more.
The unit's entry standards are course-internal safety standards, prerequisites to participate in these jumps, not jump permissions, licences, crests or endorsements of any kind. Any drop zone may adopt them as local policy; this curriculum only recommends them.
Applies to flyers competent in an angle slot on both belly and back (FFP-AN201).
No jump in this unit passes through vertical, so the track's through-vertical standard, head-down competence at crest standard for every participant, because everyone on a through-vertical jump is momentarily flying head-down, applies from FFP-DY303 onward, where it is verified (the project's coaching doctrine, standard scope clarified by The Freefly Project 2026-07-26). Environment: sky, with tunnel drills (back carving, back-fly fall-rate range) as preparation. Supervision: the coach leads a 2–3-way from the belly, dynamic jumps are led on belly, and the belly leader holds full ground visual while the group flies the back slots.
Group size guide: 2–3 plus the coach-leader, growing up the dynamic group-size ladder, 2-way, then 3-way, then 4-way; over 6 is dedicated-team territory, and the coach designs every jump around the least experienced flyer (USPA SIM 5-10.E; Spaceland movement policy).

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.

3.2
Hold the back slot with continuous visual on the leader as the group steepens toward vertical, staying on level and in slot through the dive. The coach judges slot competence as a whole, approaching from within your quadrant and holding position, rather than against a measured distance.

Can you hold a back slot with continuous sight of the leader as the group steepens toward vertical, staying on level?

3.4
Regulate closing speed on every approach so as never to pass the leader; if overtaking, slow and hold position.

Do you regulate your closing speed so you never pass the leader, slowing and holding position if you start to overtake?

3.6 Safety critical
Execute the lost-leader protocol immediately on losing visual contact, already below the group: stay on back, shallow onto a following back angle, and follow the group from below; level with or above the group: hold the shallow back angle, never descend to chase, and deploy higher after checking above.

If you lose sight of the leader, do you stay on your back, shallow onto a following angle and follow the group from below?

Screen 3 · Safety and altitudes

Safety and altitudes

Everything here is a recommendation with a reason behind it, not a rule. The drop zone you are jumping at, and your own limits on the day, decide what actually happens.

Safety-critical criteria on the short list

3.6
Execute the lost-leader protocol immediately on losing visual contact, already below the group: stay on back, shallow onto a following back angle, and follow the group from below; level with or above the group: hold the shallow back angle, never descend to chase, and deploy higher after checking above.

If you lose sight of the leader, do you stay on your back, shallow onto a following angle and follow the group from below?

Everything this unit says about breakoff and deployment

1.4
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 for a back flyer, split by position, already below the group: stay on back, shallow onto a following back angle, and follow the group from below; level with or above the group: hold the shallow back angle, never descend to chase, and deploy higher after checking above.
4.1
Initiate breakoff at the briefed altitude (within −0/+300 ft).
4.4
Deploy at the planned altitude after clearing airspace.

Altitudes here are the guides this curriculum recommends and argues for. Where the drop zone briefs something different, the drop zone is what you fly.

Screen 4 · After the jump

After the jump

From this unit's own closing element, review.

5.1
Debrief against the declared objective using video.
5.2
Analyse own dive and pull-out on video for slot displacement and level error through the pitch changes, 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. "DY201 near-vertical back angle"), criteria results and current standing against the entry standards, the curriculum gives log entries meaning.

One fault, one correction

Before the video, before anyone else speaks: name the single thing that went wrong, and the single thing you will do differently next jump. One of each. A list of six is a list you will not 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

Most records are the flyer's own, and that is the point: your own read of your own flying is worth keeping. A record only counts as verified once a coach signs it.
