Angles 402 — Fly mixed-orientation angles

Application

The flying half of the Angles 400 mastery tier: tight, fast angle jumps flown across mixed orientations, slight belly, back, head-up and head-down, with transitions from back to belly and belly to back, never through vertical. The through-vertical case is Dynamic doctrine (FFP-DY201 onward), not angles: staying off vertical is the boundary that keeps the jump an angle (the project’s coaching doctrine round-4 doctrine).

The organiser’s half of the tier, multi-group movement days and big-way angles, is FFP-AN401. One course, one job: this card is the mixed-orientation slot and the transitions that hold it.

Every jump in this unit is a led group: the active leader flies belly-to-earth, always, and flyers join only with a trained or approved leader (APF006 §5.12; the project’s coaching doctrine belly-led doctrine). Groups stay small, sized to the least experienced flyer, and smaller than an equivalent single-orientation angle group, because every orientation change is a fall-rate change waiting to happen.

Head-up angle content runs at 4 or fewer with more experienced participants (the project’s coaching doctrine round-4 doctrine).

Environment: sky for the movement content; the tunnel evidences orientation control and transition mechanics only, navigation, breakoff and group flow are sky-only.

Mastery tier: there is no sign-off. Completion is a milestone recognising mixed-orientation angle capability, not a permission to lead, organise or approve any jump.

Pre-requisite units

FFP-AN202 (endorsement-standard angle flying, both orientations), with head-up and head-down control at the FFP-HU102 / FFP-HD102 standard for the orientations the jump passes through. Leading a mixed-orientation angle group additionally requires FFP-AN302 (lead an angle jump), and for head-up content the head-up-movement capability there. RPL route: see the RPL evidence set below.

The orientation problem

What makes a mixed-orientation angle harder than a single-orientation one: each orientation on the line, slight belly, back, head-up, head-down, has its own natural speed range, so every transition is both a position change and a potential fall-rate change.

The skill that holds the group together is speed range: a wide, controlled band of speeds on both belly and back, so a change of orientation never becomes a change of fall rate that scatters the group (the project’s coaching doctrine round-4 doctrine). The discipline that keeps it an angle is the vertical boundary: transitions run back-to-belly and belly-to-back around the line of flight, never through vertical.

Elements and performance criteria

1. Plan the jump

1.1

State the line, the orientations in play, each transition point and who keys it, and own slot through each phase.

1.2

Plan every transition back↔belly, never through vertical. A jump that passes through vertical is planned under Dynamic doctrine (FFP-DY201 onward) with its gates, not as an angle jump (the project's coaching doctrine round-4 doctrine).

1.3

Compose the group around its least experienced flyer, smaller than an equivalent single-orientation angle group; head-up angle content runs at 4 or fewer with more experienced participants (the project's coaching doctrine round-4 doctrine).

1.4

Set the breakoff to the angle standards, guides 5,000 ft up to a 4-way, 5,500 ft for five or more, and raise the floor for head-up content: minimum 6,000 ft, 6,500 ft for a larger group, with the head-first transition initiated by ~6,500–7,000 ft (Carlton). Keep at least 1,000 ft between breakoff and planned deployment (mandatory in Australia, the APF Operational Regulations) (the project's coaching doctrine breakoff standards; FFP-AN301 knowledge evidence).

1.5

Declare the jump and its lane to the load per the FFP-AN301 planning standard, a mixed-orientation angle is a movement group like any other and owns a lane, a distance and an opening area.

2. Prepare

2.1

Brief each transition with a positive key that reads from every orientation on the line, a back-flyer and a belly-flyer see different pictures, so the key must work for both.

2.2

Screen every participant by demonstration, not self-report: orientation control on both belly and back, fall-rate range, and footage, an unproven flyer is treated as lower-skilled until seen (the project's coaching doctrine screening doctrine).

2.3

Complete a freefly-standard gear check for every flyer, the jump carries freefly speeds in the head-up and head-down phases (the APF Operational Regulations audible in Australia; APF006 §3.1).

2.4

Brief the what-ifs: the left-behind protocol, the high-and-behind case, and the abort to a briefed straight-down plan B (FFP-AN301 standard).

3. Perform

3.1

Hold slot through orientation changes: change orientation without changing level or closing speed, bridging the fall-rate difference with speed range on belly and back rather than letting the transition scatter the group (the project's coaching doctrine round-4 doctrine, the participant speed-range skill).

3.2

Fly each transition on the leader's key, staying on the line of flight, for head-up-to-head-first conversions use a team layout around a centre point, never the in-place layout Carlton names as the worst option (Carlton; the project's coaching doctrine round-4 doctrine).

3.3

Never transition through vertical. If a transition goes long or unstable, recover to the nearest stable orientation on the line and rebuild the slot, never over-rotate through vertical to save it (the project's coaching doctrine round-4 doctrine).

3.4

Hold the briefed heading discipline (within about ±45° of the planned leg) and the lane, to the same navigation standard as any other movement group (FFP-AN302).

3.5

Stay predictable when someone struggles, and never chase a flyer who leaves the plan, in-slot recovery, never track away from an angle group (APF006 §4.3).

4. Complete — breakoff to landing

4.1

Where head-up content is flown, be head-first by the briefed window (~6,500–7,000 ft) so the track has spent its acceleration lag before the breakoff floor arrives (Carlton, the 1,500–2,000 ft lag; the project's coaching doctrine round-4 doctrine).

4.2

Initiate breakoff at the briefed altitude in the briefed fan, each flyer tracking in a head-first orientation, peeling no more than ~90°, never turning back toward jump run (APF006 §5.10; the project's coaching doctrine breakoff standards).

4.3

Deploy at the planned altitude after visually clearing the airspace in all directions, always assuming somebody is there (APF006 §3.3).

4.4

Fly the briefed canopy plan, and confirm the whole group is down before standing down.

5. Review

5.1

Debrief against video to the protocol: participants first, the whole video once through, safety points first, end on a win.

5.2

Locate every fall-rate excursion at a transition and attribute it, key timing, speed range, or orientation mechanics, and name one correction to train next.

5.3

Log the jump naming the unit, the orientations and transitions flown, and the next focus.

Bold criteria are safety-critical: non-compensable (any Not Yet Satisfactory on a bold criterion = unit Not Yet Competent).

Foundation skills

• Orientation-agnostic fall-rate control, a wide speed band held on belly and on back.
• Reading a transition key from any orientation.
• Slot flying at freefly speeds.
• Honest self-assessment across four orientations, not just the strongest one.

Performance evidence (suggested sufficiency — a guide to how long it might take; adjust locally)

Ability evidenced across a suggested 10 mixed-orientation angle jumps in led groups:

• Transitions in both directions (back-to-belly and belly-to-back) held in slot.
• At least 2 jumps including head-up content at the raised breakoff floor.
• Consecutive jumps flown and broken off to plan.
• Across at least two different days and wind pictures.
• Within a recommended 12-month currency window. Tunnel time evidences orientation control and transition mechanics only.

Knowledge evidence

• The orientation boundary. Explain why mixed-orientation angles never transition through vertical: the through-vertical case is Dynamic doctrine with its own gates (everyone on a through-vertical jump is momentarily head-down), and staying off vertical is what keeps the jump an angle rather than a dynamic jump (the project’s coaching doctrine round-4 doctrine; FFP-DY201).
• Speed range as the load-bearing skill. Explain why every transition is a potential fall-rate change, and how a wide speed band on both belly and back lets a flyer change orientation without changing level or closing speed, and why the group is capped smaller than a single-orientation angle group of the same experience (the project’s coaching doctrine round-4 doctrine).
• The head-up angle numbers. State the raised floors (minimum 6,000 ft, 6,500 ft for a larger group) and the transition-initiation rule (head-first by ~6,500–7,000 ft), and the Carlton evidence behind them: no glide-ratio gain moving into a head-up breakoff, a measured 1,500–2,000 ft lag before horizontal speed builds after converting.
• Modelled 6-way separations of 268 ft (≈1.4 s) slow and 392 ft (≈2.7 s) fast head-up versus 690–1,165 ft head-first, six-plus “unacceptable”, five “pushing it”, which is why head-up content runs at 4 or fewer (Carlton).
• Transition technique. Describe the team layout (converting to head-first around a centre point while staying on the line of flight) and why the in-place layout is the named anti-pattern (it loses the line and the acceleration lag bites hardest) (Carlton; the project’s coaching doctrine round-4 doctrine).
• Why the leader stays on belly. Explain why even a mixed-orientation angle group is led from the belly only, and how any design that seems to need a back-flying leader is solved with a belly-to-belly leadership handover instead (APF006 §5.12; the project’s coaching doctrine; FFP-DY201 doctrine).
• The screening doctrine. Explain why self-reported answers cannot vet mixed-orientation skill, and the demonstration screens that can, orientation control both sides, fall-rate range, proximity footage.

Assessment conditions

Sky, in led groups, with the assessing coach on the jump. Sky jumps from a recommended 12,000 ft minimum, mixed-orientation transitions need working time. Video is the primary debrief and evidence tool; footage from within the group or from the leader’s slot, paired with the candidate’s talk-through. Required equipment: visual altimeter, functioning audible set to the briefed profile, AAD recommended, freefly-suitable gear.

Conditions within every participant’s cleared limits. Assessor: a freefly coach current in movement jumps and mixed-orientation flying, using the published FFP-AN402 checklist (Satisfactory / Not Yet Satisfactory per criterion; unit result Competent / Not Yet Competent, recorded as a Mastery milestone).

Coaching priorities

Deliver in the project’s priority order: Safety → Fun → Learning (curriculum Part A0). Mixed-orientation angles are among the most fun jumps in the sport, that is exactly why the boundary and the breakoff floors are non-compensable: the flyers this unit serves will fly these jumps anyway, and the card exists so they fly them inside a plan, with a leader, at floors that buy the separation back.

Debriefs end on a win with one focus for the next jump.

RPL evidence set

For experienced mixed-orientation angle flyers the flying is the evidence. Logbook and video of mixed-orientation angle jumps showing held slots through transitions in both directions, head-up content at the raised floors, and orientation-aware breakoffs; a word from a recognised coach or leader; plus one challenge jump against this checklist with a qualifying assessor.
