Dynamic · Relative · The brief

Dynamic 201

Fly a near-vertical back angle

Holding a back slot as the line steepens toward vertical and shallows back out.

What the course is about

You'll learn to hold a back slot as the group dives toward vertical and pulls out onto the line it came in on. Angles 203 comes first, because you fly this course in a back-fly slot. Your coach checks your belly and back before you start, because dynamic jumps use both.
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 to watch

What to watch

The same short list the flyer sees on their card, in the same words.

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 your back slot on level with continuous sight of the leader as the group steepens toward vertical?

3.3
Hold the back slot through the pull-out as the group shallows back onto the entry line, matching the leader's pitch and speed changes.

Can you stay in the back slot through the pull-out, matching the leader’s pitch and speed as the group shallows back onto the entry line?

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 and follow from below, never descending to chase if you are level with or above the group?

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.

Safety-critical items 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 and follow from below, never descending to chase if you are level with or above the group?

Everything this course 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.

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 10,000 ft or higher (recommended), with a real group of 2–3 plus the coach-leader.
Video of every assessment jump, with the flyer identifiable: leader-flown, outside or helmet-mounted. An assessment without video is not valid.
Equipment: a visual altimeter, a working audible, an AAD (recommended), and freefly-suitable gear.
Conditions within the flyer's cleared limits. Calm to mild upper winds are recommended for assessment jumps.
The assessor is a freefly coach current in both angle and vertical coaching and approved to lead movement jumps at the host drop zone, working from this checklist.
Each criterion is marked Satisfactory or Not Yet Satisfactory, and the course as Competent or Not Yet Competent.
The result is internal to these courses. It opens Dynamic 202 and jumps of this format within the curriculum, and gives no licence, crest, endorsement or jump permission.
As a guide, it takes at least four coached group jumps, at least two of them with the full dive and pull-out, over at least two days within six months.
One skill-building jump can be tunnel time on back carving and back-fly fall rate.
If you already fly steep back angles, your coach can assess you on one near-vertical back angle behind a coach-leader, with your logbook, tunnel records and video. Finishing gives you no licence, crest or jump permission.

Performance evidence

After each jump, debrief the video with your coach, find where you slipped out of slot or off level, and log one correction. You've finished Dynamic 201 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.
The entry standards are course safety standards for taking part in dynamic jumps. Say so in every briefing: they are not jump permissions, licences or crests. A drop zone may adopt them as local policy.
Evaluate each flyer on belly and back, and put the development work into the weaker side, usually belly. The same evaluation sets which side the flyer starts on for the first pass-through at Dynamic 303.
Have the entry-standard conversation openly, before the flyer spends money. For a flyer below the standard, offer the belly and back angle courses as the path in.
Explain the tier's design up front as a safety decision: pulling out the way you came in lets the flyer meet near-vertical speed and pitch before any jump passes through vertical.
End each debrief on something that went well, with one thing to improve, and present the dive and pull-out as the way into dynamic flying.

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.
